Dry Humor, Wet Biofilm: A DentalBuzz Look at Periodontal Desiccation Therapy

May 7, 2026 By Trish Walraven Leave a Comment

Sci Fi Hygienists destroying a biofilm creature

Every few years, dentistry finds a new way to fight periodontal disease, and every few years the dental community collectively narrow our eyes and says, “Okay, but does it actually work?”

Lately, desiccation therapy products like HybenX or PerioDT have been showing up in more periodontal conversations. Maybe a hygienist in your office came back from a seminar (thank you, Anne Guignon!) ready to dry out every periodontal pocket in sight. If you’re a patient, maybe you’re here because you want to learn more about “that new bacteria treatment thing” you saw online. Honestly, after dealing with enough stubborn 7-millimeter pockets, almost anything that sounds biologically plausible gets people’s attention these days.

Periodontal disease is perpetually frustrating. Deep pockets that can cause teeth to eventually fall out can improve beautifully in one patient and stubbornly linger in the next, despite thorough and frequent deep cleanings (scaling/root planing – SRP), excellent home care, and enough flossing guilt to power a small suburb. Dentistry has spent decades trying to find ways to improve outcomes beyond traditional SRP alone. We have tried local antibiotics, lasers, chlorhexidine chips, peroxide trays, antimicrobial rinses, photodynamic therapy, probiotics, and approximately seven bajillion products containing the words “biofilm disruption”. Now we are drying it out.

At first glance, desiccation therapy sounds slightly dramatic, like something involving tiny industrial fans under the gums, or terror-inducing like a classified bioweapon designed to remove every trace of moisture from human tissue. In reality, products like HybenX and PerioDT are chemical desiccants placed into periodontal pockets before or during SRP. Instead of functioning like antibiotics, they work by dehydrating and disrupting the biofilm matrix itself.

This is interesting, because biofilm is not just bacteria sitting politely on the tooth surface waiting to be removed easily with a daily brushing. It is an organized, sticky protective environment that allows pathogens to thrive while resisting both the body’s immune response and our increasingly creative attempts to evict them.

Desiccation therapy basically attempts to collapse the slime layer so instrumentation can work more effectively afterward. And that is probably why so many hygienists are paying attention. It feels mechanically logical. There’s less of “kill all the bacteria” and more focus on making the neighborhood unlivable.

That also separates it from many of the periodontal adjuncts we have relied on for the last twenty years. Arestin and other localized antibiotics attempt to suppress bacterial growth directly after SRP. Perio Protect approaches the problem from home, asking patients to wear peroxide trays daily over time. Lasers promise bacterial reduction with varying levels of scientific enthusiasm depending on who is presenting the lecture and how expensive the laser was.

Desiccation therapy lands somewhere in the middle. No expensive equipment. No prolonged antibiotic exposure. No hoping patients suddenly develop Olympic-level compliance with home care routines. And that last part matters more than we like to admit.

Perio Protect can work very well for motivated patients, but every hygienist reading this has heard patients swear they’re cleaning their teeth well while staring directly at enough interproximal bleeding to suggest otherwise. Compliance has always been the weak spot in periodontal therapy. The most exquisitely engineered home-care system in the world still depends on a human being deciding to use it consistently after dinner when they are tired and watching Netflix. Desiccation therapy removes that uncertainty. The treatment happens chairside, under clinician control, during the appointment itself.

That does not mean that desiccation therapy is magic.

The research so far is promising, but not definitive. Studies have shown improvements in bleeding reduction and pocket depth when desiccation therapy is used alongside SRP, particularly in deeper or inflamed sites. At the same time, the evidence base is still fairly young. Long-term data is limited, protocols vary, and we are nowhere near the point of calling this standard therapy for every periodontal patient walking through the door. Which is probably exactly where reasonable clinicians should land right now: we should be interested, but not hypnotized.

Desiccant in gingiva

There is also the small matter that these products are not nearly as gentle as some marketing language might imply. The SDS sheets for HybenX and similar products contain repeated warnings about corrosive effects, tissue irritation, and careful handling due to their sulfuric acid and sulfonated phenolic chemistry. This is not simply another tooth gel. Used appropriately, desiccation therapy appears safe and effective as an adjunctive treatment. Used carelessly, it is still a highly acidic chemical agent being placed into inflamed tissue.

That nuance is important because dentistry sometimes struggles to occupy the middle ground between cynicism and infomercial. Every new periodontal adjunct gets treated either like a revolution or a scam, when the reality is usually much less exciting and far more useful.

Most periodontal therapies help a little. Some help certain patients a lot. None exempt us from the fundamentals. Good instrumentation still matters. Maintenance still matters. Smoking, diabetes, xerostomia, stress, medications, and home care still matter. Biofilm remains deeply unimpressed by marketing campaigns and dramatic product names.

Still, desiccation therapy may end up carving out a meaningful place in periodontal care because it approaches the problem differently. Not by adding another antibiotic to the mix, but by disrupting the physical environment that allows pathogenic biofilm to organize itself in the first place.

And honestly, after decades of trying to chemically negotiate with bacteria, there is something deeply satisfying about simply drying out the sleazy slime condo and telling the whole microbial neighborhood to move out.

Congratulations to the bacteria on losing their security deposit.

CareCredit: The Easy Way Billionaire Banks Fill Cavities in Their Profits

October 6, 2025 By DentalBuzz Staff Leave a Comment

Fact check: DentalBuzz first wrote about CareCredit in 2008, our very first year online. At the time, subprime lending was steering the nation into a deep recession. Regulators eventually closed many of those loopholes, but when it comes to medical lending, the risks have only grown worse.


Della thought she was just getting a tooth pulled. She left the office with a numb jaw, a $1,000 charge, and a brand-new CareCredit account she never asked for.

David went in for a cleaning. Weeks later, a Synchrony Bank credit card showed up in his mailbox with $1,000 already billed to it.

Victoria didn’t even get her teeth fixed, but somehow still got sued for thousands when a dentist’s office charged her CareCredit account without her knowing.

These aren’t outliers. They’re the blueprint. And if you’ve ever been in a dental chair with a clipboard on your lap, you know exactly how easy it is to sign away more than enamel.

How the Scam Gets in the Chair

Medical credit cards like CareCredit market themselves as patient-friendly: “No interest! Easy payments!” But behind the bright colors and soft music is a trap.

Here’s the magic trick: deferred interest. You’ll hear “zero interest” if you pay it off in six, twelve, or eighteen months. What you won’t hear is that if you slip up (even by a single penny), the bank retroactively slaps on 25–33% interest on the entire balance from day one.

So your $3,500 implant? Now it’s a $4,000+ landmine. And all you did wrong was believe your dentist’s assistant when she said “stress-free financing.”

Why Dentists Are Playing Banker

Let’s be fair: dentists aren’t rubbing their hands in the back office like cartoon villains. They’re dealing with slow, stingy insurance reimbursements. CareCredit offers them payment in two business days. Compared to weeks of haggling with insurance companies, it’s easy to see why dental teams say yes.

But for patients, this shortcut is a trapdoor. Signing financial contracts while you’re in pain, or even under anesthesia, is not informed consent. It’s duress with a signature line.

What’s Broken Here (Hint: It’s Not Just Teeth)

This problem is a symptom of a bigger disease: the U.S. healthcare system. Because dental insurance these days rarely covers more than $1500 per year per patient, lenders like Synchrony have found a back door into the exam room. Dental staff, who are trained through online modules, not by having finance degrees, are suddenly doubling as loan officers.

And let’s be clear: there should be no door in the dental office that opens to a bank.

For Patients: What you can do

  • Pause before you sign. Tell the staff you’ll take the paperwork home first.
  • Spot the red flags. If you hear “no interest,” immediately ask: Is it deferred interest?
  • Watch your credit. Patients often learn about CareCredit accounts only when the bill (or a lawsuit) arrives.
  • Know your rights. Some states are banning deferred-interest medical credit or requiring patients to fill out their own applications instead of letting staff do it.

For Dental Teams: A Gut Check

Patients come to you because they’re in pain, not because they need a crash course in consumer lending. If you wouldn’t hand an extraction patient a car loan in a vulnerable moment, why hand them a credit card app?

Remember: a patient who feels scammed won’t come back. And they’ll tell their friends, loudly. Synchrony might pay fast, but the long-term price is patient trust.

The Bite at the End

CareCredit works because insurance doesn’t. Dentistry should be a partnership in health, not a transaction in debt, and until the system changes, both patients and providers are caught in the same trap.

Off-Label and Totally Legal: What the FDA Won’t Say About Fluoride Varnish & SDF

May 29, 2025 By Trish Walraven Leave a Comment

Fluoride Varnish and Silver Diamine Fluoride (SDF)

 

 

Let’s play a little game. Imagine your fluoride varnish brush could talk. You pick it up, ready to slather it across the facial and lingual surfaces of your patient’s teeth, and it whispers:

Psst… I’m only here for sensitivity.”

Excuse me? We both know that’s not the real reason you’re using it. You’re using it to prevent cavities. So why the double life?

Not-So-Secret Agents: Fluoride Varnish & SDF

If you work in dentistry, you know there are two magical fluids we love using to fight decay without breaking out the drill: fluoride varnish and silver diamine fluoride (SDF).

But here’s the kicker: neither is FDA-approved for the thing we all use them for – you know, the actual preventing or arresting of cavities. They’ve got their little badges that say, “I’m here to reduce sensitivity,” and that’s it. It’s like hiring a security guard to scare off pigeons and they stop a bank robbery instead. Not exactly their “official” job, but they’re killing it nonetheless.

So… are we doing dentistry wrong?

Not at all. This is what the grown-up version of medicine looks like: off-label use. That means we, as clinicians, are allowed to use products in ways that aren’t specifically written on the packaging, as long as there’s good science behind it and we’re not just winging it with snake oil and hope.

Fluoride varnish has been used off-label for decades to prevent caries. Every major dental organization (ADA, AAPD, CDC) backs it. It’s reimbursed by Medicaid for that purpose in many states. Even pediatricians – outside of a dental setting – are authorized to apply fluoride to children’s teeth under certain medical guidelines. But the label? Still just for hypersensitivity.

Silver diamine fluoride (SDF) – same deal. It got FDA clearance in 2014 for sensitivity. But its real superpower is stopping decay in its tracks. You paint it on a mushy lesion and – bam! – it freezes like Elsa just sang at it. Black, hard, ugly-but-healthy decay. Not glamorous, but incredibly effective, especially for kiddos, elders, and patients who can’t tolerate traditional treatment.

Why not just change the label?

Here’s the not-so-fun part: getting a new FDA indication is expensive. Like, “we could build a small dental school for this money” expensive. Most of the companies that make fluoride varnish and SDF are not Big Pharma. They’re more like Little-To-Medium-Sized Dental Supply. If their product is already being widely used and endorsed for the off-label thing? Why spend millions for a gold sticker that says “Approved”?

Also, if it ain’t broke (and no one’s getting sued), they’re not fixing it.

The ethics and the eyebrow raises

Now, I’m not saying you shouldn’t know what’s on-label and what’s not. It matters. Patients deserve transparency, and we owe it to them to explain why their kid’s teeth are turning black (SDF, looking at you) or why we’re applying fluoride varnish after a cleaning even though they don’t have “sensitive teeth.”

The next time you brush on that fluoride varnish or dab a bit of SDF, give a little nod to its secret identity. Off-label? Definitely. Totally legal? You bet. Cavity-fighting? That’s the plot twist they didn’t print on the package.

TL;DR for your patients (and curious colleagues)

  • Fluoride varnish: FDA says it’s for sensitivity. We use it for cavities.
  • SDF: FDA says it’s for sensitivity. We use it to stop decay cold.
  • Both are off-label for caries, but not off-limits.
  • Science is on our side.
  • No one’s getting arrested. (Except maybe the cavities.)

What’s your take? Are we stretching the label, or just catching up to the science? Will this be one more talking point for those on the anti-fluoride side? Share your thoughts in the comments.

Why dental insurance makes good people do bad things

January 10, 2018 By Trish Walraven 32 Comments

When I was a kid, my dad would tell me on the way to the dentist to be prepared to pay out of my own pocket for any cavities I had. $38 per filling was an insane amount of money for an eight year old with a 75 cent allowance per week and 7-Eleven candy habit. I hedged my bets that his threats were empty, that I’d get my dental care and never have to pay up.

And it worked. Since I didn’t have a proper income, my parents went ahead and took care of the bills for me, got me to the dentist, fixed those cavities right up. Instead of making me pay in cash, however, I paid up in guilt, for not taking care of my teeth like I should have.

I carried that guilt for years, right into college and ultimately into dental hygiene school, when I learned something interesting about the type of fillings that were in my teeth: if I’d had sealants as a child, there would have existed the possibility for me to grow up cavity-free. But sealants weren’t widely available to dentists until the mid-1980’s, too late to save me from the drill.

That’s the thing, though. Dental practice is not malpractice if it’s within the current standards of care, so my dentist growing up was in no way neglectful of my dental health. It’s just the way things were then. I have a bunch of pits and fissures in my back teeth full of silver instead of smooth white sealants, like my kids do – all those deep grooves they inherited from me were sealed just as soon as their permanent teeth came in.

Dentists and hygienists have a belief ingrained in us throughout our education: The best dentistry is NO dentistry, because natural healthy teeth will almost always be better than man-made teeth. We are driven to help you keep your teeth in their most natural state as possible, for your entire life. We can’t do this, though, unless you visit us for preventive care. Our experience and training lets us see the earliest signs of things that aren’t quite right in your mouth, so that we can help you take the necessary steps to correct them way before they become disfiguring, painful, or expensive.

This might be a good time then to start talking about dental insurance. Before we do that, though, let’s explore more generally. What is insurance? It’s money you pay to someone else to take care of things if the unexpected happens.

If you’re fortunate enough to never have a house fire, or die, or crash your car, there’s nothing that your insurance policies need to cover, so you’ll never get a reimbursement check. Medical insurance used to be a reimbursement system, too, until insurance companies had to come up with clever ways not to cover people’s health problems so that the insurers wouldn’t run out of money. Hospitals and doctors also became clever with their billing, and this back and forth game of “how can we make the money flow in our direction” has resulted in our current health care situation.

This cleverness has also invaded dentistry. Here are three truths that exist right now:

1. A lot of people have crappy dental plans

2. They go to dentists they don’t trust and

3. Get treatment they don’t need.

Do you want to help me change these three truths? You can, you know. We’ve done it before, you and I. You helped me get the word out that plastic in toothpaste was a bad idea, and we got that banned in the United States shortly afterwards. This is so much bigger: helping each American keep their teeth for life, at a cost they can afford.

To do this, we’re going to have to get everyone working together, but differently. You can’t change the system by just saying it needs to be changed and then doing nothing from your place within it. There’s also no ability to change if you don’t understand how to make a difference with your own actions. Right now, inadequate dental insurance is the standard of care, sort of like silver fillings were in the 70’s. Are you ready to help me move dentistry another big step forward?

Look at yourself in the mirror.

This is where it starts. With you. What do your teeth mean to you? Are their appearance important, or is it good enough that they don’t hurt and you can chew with them? Take a hard look at your teeth, and answer these two questions honestly to yourself.

Believe it or not, dentists spend a lot of time trying to guess people’s values. If you don’t know how you feel about your own teeth, then how does your dentist decide what’s right for you?

Natural teeth are going to be everyone’s first and best option. You get the first two sets of teeth for free – they’re given to you, as part of your body. If you’re fortunate enough to have parents who were able to take you for early dental care, who reminded you to brush your teeth regularly, who did their best to manage your habits and your diet, then you are less likely to need a third set of teeth. Without getting into details, let’s agree that anything dentist-made in your mouth which takes the place of natural teeth is part of the “third set.”

That dentist-made stuff, though, is the set of teeth that ends up costing a lot of money. Fixing teeth is how dentists stay in business, after all. But it’s also where insurance breaks down, on that third set of teeth. Even the best plans only cover, at most, the dollar equivalent of about 2 dentist-made teeth per year. If you have 28 teeth, that means you’ll have to use up all your benefits, every year for 14 years to get your third set of teeth paid for. If your insurance only pays for 2 teeth per year, but you have 10 teeth that are in trouble, what do you do, only treat a few and let the others all rot while you’re waiting on your insurance checks?

Something else you need to admit to yourself is to make the realization that you’re not immune to the lure of the bargain. Too often, that’s all dental insurance is. It’s sold to you as a bargain, or something that you have to have to get in the game, when the reality is that it’s only a game. Take this example:

Yep, that insurance made a $755 dent, which is big. But at what cost? Were the fillings and crowns built to last, or will they need to be replaced in less than five years since you felt you had no other dentist who would take your insurance and the one that you did go to didn’t seem to do that great of a job?

Let’s back up now and talk about your first two sets of teeth. You get the baby set as a toddler, the other set as you grow up. Both of those sets of teeth don’t cost anything; they just sort of show up one day, ready to get to work. And they need a dentist to check in with them every so often, to say hey, howya doin? Everything all right in there?

That’s what most people think of as a check up, and if you’ve had good luck with your teeth so far, it’s safe to say that having at least one dental visit per year will assure that someone’s keeping a professional watch on them.

Checkups are cheap.

Can you afford $50 per year? That’s the current average cost for a routine dental checkup in the US, across all dentists – city dentists, rural dentists, group dentists, solo dentists.

If dental checkups are not crazy expensive, then why isn’t this common knowledge?

Have you assumed that basic checkups cost more than $50? If you have, you’re like most people. It’s probably why you’ve been worried about the cost of going to the dentist, why you’ve been worried about not having insurance, why you make sure that the dentist you choose takes your plan, why you visit low cost clinics. You haven’t known the cost of the alternative.

This knowledge is your power. You can go to any dentist, and $50 is the average price for a periodic examination – this what they will charge to take a look at your mouth during a routine visit. It’s a little more for your first time, say $75-$100. A series of four bitewing xrays? Usually less than $60. Certainly not free, but all together not as much as you may have imagined.

So let’s bring insurance into our discussion once again. Remember, insurance, for everything except your body, pays nothing until there’s an unexpected event. A dental checkup is not unexpected – it’s prevention! And if you’ve ever worked with dental insurance, you know this: Almost every dental insurance policy completely covers the cost of a checkup. But they don’t do so universally. With many of those checkups, your insurance will only cover the cost if you visit certain dentists.

Dental insurance pretends to pay for your teeth.

If it really paid for them, like insurance is designed to do, it would cover the unexpected problems, especially in emergency situations. Instead, dental insurance gives you just enough coverage to make you feel like it’s a value, and scares you into thinking you can’t go to the dentist without it. Most plans offer a fixed dollar amount, around $1000, to use per year, and that’s it. If repairing your teeth costs significantly more than your maximum, it’s not protecting you. Dental insurance shouldn’t even be called insurance, because it works more like a dollar-off coupon. $1000 off of a $6000 treatment plan is at best only a 17% discount. Call yourself a sucker if you tolerated care at your “in network dentist” so that you could get less than 20% off the cost of going to a dentist of your choosing.

Dental insurance changes how dentists care for you.

We have been conditioned to believe that a procedure must be the right thing to do because “insurance will pay for it.” There is a sweet spot, right in the middle of insurance plans that covers so much more of a percentage of the total cost than either end. People with healthy teeth get basically a 20% discount for the cost of their care after taking premiums into consideration. It’s also 20% off of the cost of really expensive needs like crowns and dentures. But look how the dental benefit skews within the middle tier of dental needs:

Whoa! It jumps up to 60%. This can go one of two ways:

1. There are a few things you really need to have done, and insurance will help out a lot!

2. Your insurance will get billed for stuff you don’t need because you won’t have to pay for it yourself.

This doesn’t bother me all that much for preventive care because it’s not permanent and mostly reversible. But when dental offices intentionally “massage the insurance” to abuse this 60% sweet spot, a dentist might take a drill to a tooth that didn’t really need it, and guess what? You’re damaged. You’ve actually been broken by someone you trusted to take care of you. They took out a piece of your tooth, forever, and you can never grow it back.

Destroying healthy tooth enamel for profit makes me angry.

I’ve seen this dressed up at dental practices to make it sound like they have patient’s interests in mind. It might be called “their philosophy of care” but really, you’d be surprised how many people exist whose paychecks are dependent upon exploiting insurance codes to get the most money for their practices. “Maximizing fee schedules” is their philosophy of care. And you are a pawn to them. This is the essence of why dental insurance makes good people do bad things.

 

Exploiting Insurance Codes for Maximum Dollars.

Let’s blow this up a little and list some of the ways that insurance is abused. You may want to be on alert when you see these on your treatment plan or billing statement:

Core Buildups. This article from the American Association of Dental Consultants states, “In the last twenty years there have been a reported increase in the number of core buildups submitted to dental benefit plans out of proportion to the increase in crown submissions….Also growing are the numbers of dentists who admit, with no compunction, that they place core buildups under every crown they seat regardless of need. The financial ramifications from this trend are significant since a core buildup can add twenty to thirty percent to the final cost of a crown.”

Periodontal scaling and root planing. Often called a “deep cleaning,” gum disease treatment is the primary weapon against tooth loss, but it is a time-intensive procedure. If an office charges out periodontal therapy but you weren’t even numbed, or it took less than an hour to have treatment in all four sections of your mouth, that’s a reason for your eyebrows to go up. Also, be cautious of any dental office where your routine cleaning appointments seem super-speedy, according to this article, or if you’ve always been healthy like this person.

The need for many fillings suddenly. You’ve been off and on with regular dental care, and have had few fillings in your life. Then you visit a new dentist and are told that you have a lot of cavities. According to this article from the New York Times, some doctors may wait longer than others and “watch” small cavities, but if you feel suspicious, you should definitely seek a second opinion before the drilling starts. One pediatric dentist’s editorial on the ADA website goes so far as to call this “creative diagnosis.”

Replacement of silver fillings. Sure, they don’t last forever. But silver fillings do typically last longer than tooth-colored fillings, and if there is no pain or an obvious hole or cavity in a tooth with one, most dentists won’t try to scare you into changing them out, especially not all at once. The National Council Against Health Fraud issued this statement defending amalgams. I personally have six silver fillings that are around 40 years old, and they all still feel better than the two that were replaced.

Procedure Upselling. Any time a dental practice uses intimidation to get you to agree to something, that’s wrong, regardless of whether or not the treatment is appropriate or covered by insurance. Don’t ever feel pressured, especially if you’re in a vulnerable position, to agree to whitening, bite guards, cancer screenings, or even orthodontic care. A reputable dentist will let you take your time to make decisions about your mouth.

Suspicious dates or billing. Look over these examples of fraudulent and abusive practices; these may be signs that a practice is illegally obtaining insurance benefits on your behalf.

Preventive care is not immune.

With preventive care, dentistry as a whole tends to over-treat because, after all, “insurance will pay for it.” Big Deal, We took better care of them than they needed, who cares, we all win, blah blah. When someone feels entitled to an insurance benefit because, by George, it needs to be worth SOMETHING for all those dollars, that’s when you’ll agree when your hygienist says “see you in six months.” I guarantee that every hygienist has patients for whom getting their teeth cleaned every six months is complete overkill. Some people simply have nothing on their teeth to clean off. We spend most of your appointment scraping at stuff that’s not even there, despite our best efforts to find it. I’ve done it, lots of times, and it’s frustrating because the patient expects a cleaning every six months and we truly want everyone to feel like we’re helping them stay healthy.

That’s what I mean. There is no motivation to correct the situation. The insurance pays for cleanings every six months, so no one will challenge the perception that having your teeth cleaned twice a year is not necessary. Money is wasted, but to the patient, they “miss out on their free cleaning.”

This gets super abused in dental practices that are dependent upon patients who have insurance to stay in business. The more dependent, the more likely the abuse. That’s not to say that most dental practices are doing their best to stay within the standard of care, while carefully checking everyone’s insurance plans. Cleanings twice per year? Checkups twice per year? X-rays once per year? Everyone is treated the same. The six month visit is a safety net, and both patients and clinicians accept it because of what insurance covers, not because treatment is necessary.

On the other hand, insurance dependence can also can cause a dental practice to neglect your needs. The dentist is less likely to tell a patient to have X-rays every six months if their insurance doesn’t cover it, even if the person is suffering from severe dry mouth that is resulting in a lot of new problems that can be diagnosed with the help of more frequent imaging. If you need your teeth cleaned more often than what your insurance will pay for, an office may simply let that recommendation slide past. You are much less likely to get personalized care when you allow insurance coverage to dictate what gets done, and when. You’ve allowed yourself to be seen as “the person with insurance who is not going to pay for anything that it won’t cover.” Even if you don’t feel this way. It’s like a trap. Not just to patients, but to clinicians as well.

The Five Traps of Dental Insurance.

Trap #1: DMOs that bill for treatment above and beyond their negotiated rates. Dental Maintenance Organizations are lowest tier of dental insurance. Dentists on these plans get capitations, which are small monthly payments for being on the provider list. To be profitable they need to bill out as much treatment as they can. Patients have come for second opinions (note: always get a second opinion if you’re unsure!) after visiting a DMO practice enough times for me to see a consistent trend of overcharging for excessive care; not just hundreds, but for thousands of dollars of treatment, out of pocket. If you have insurance that only lets you go to one or two clinics that have many doctors who cycle in and out of the offices, you probably have a DMO plan.

Trap #2: Missing Tooth Clauses. Sometimes having a tooth removed is the least expensive way to get out of pain. If you’ve ever lost a tooth, unless you had your existing insurance in place, the replacement of that tooth in the future won’t get covered. So much for getting your teeth back to working order. To the insurance company, a missing tooth is considered a pre-existing condition, so it’s your responsibility, not theirs.

Trap #3: Waiting Periods. Now you have insurance, but you’ll have to wait six months to a year to pay into the system before it might give you that money back, plus a little more? Individual dental insurance plans are notorious for waiting periods.

Trap #4: Major treatment. We’ve already established that less expensive the dental service, the more likely your insurance is to cover it. What about the expensive stuff? If it costs more than $300 per tooth or section, then your insurance will most likely only cover half of that. Ever. End of story. Need dentures? A crown? A wisdom tooth removed? You’ll have to pay at least half the bill, if not more, even if you followed the rules and went to the dentist on your plan.

Trap #5: Discount dental plans. There’s one type of discount plan you should run, run, run away from – those are the referral services. They’re not really even discount plans, if the truth must be told. You pay a fee to a third party. That third party gets to keep some of your money, and in return you receive a list of dentists who will “accept” a reduced cost for a few treatments. In the meantime, the third party often encourages the dentists on their list to compensate for their reduced fees by billing for services not bound by the discount plan. I would be cautious of any dentist who uses this method to find new patients.

There would be no game of chess if the pawns refused to play.

So how do we encourage good people to stop doing bad things because of dental insurance? There’s only one way: Stop the flow of money! Have a crappy dental plan? Don’t allow your money to fund it. And if insurance abusers have no patients, they’ll eventually stop the bad behaviors.

You’d be surprised how many dentists out there would be thrilled if even half their patients decided to do everything they could to save money. The reason most dentists got into the profession? They love knowing that they’re helping people. And if the main reason you go to the dentist is to save money in the long run, they will be pleased that you chose them to partner with you to work towards that goal.

You can afford to go to the best dentists in town.

What if you could always visit the absolute best dentists, the ones that you thought only the most wealthy people visit, and you would get better and cheaper care there?

You can, and you should. The best dentist is the best, not because they cost the most, but most of the time, because they cost what you decide they cost. The best dentists have built something very important in the community that brings many people to see them.

This is where the biggest, most powerful word in dentistry comes in.

Trust.

That word goes both ways. Too many dentists don’t trust their patients to make good choices about their teeth, so they often only present one option. This is it, period. This is what your mouth needs, like it or don’t, but this is what you need, and what it costs, and this is just what we do around here and how we do it.

Instead, a good dentist will listen to the people they serve carefully, and trusts that the patient will share enough about their concerns to be able to formulate several options, not just a single option, especially for more complex care. If the financial burden even to get someone out of pain is too much, the “best dentist” is still the best value for an honest opinion. Think of them as the gatekeeper, the one who knows which dentists in your neighborhood to steer clear of, the ones who do not seem to value trust.

But they don’t take my insurance.

Seriously, you came through all of this with me, and you’re still stuck on insurance? Do you want dentists to treat your insurance, or do you want them to treat you? A good dentist’s goal is to put you in charge of your own care, and follow your values as much as possible, which is how you’ll truly end up saving money.

Should I keep using my insurance?

Sure! If you’re lucky enough to have even minimal dental insurance and you trust the practice where you’re already a patient, there’s no compelling reason to make a change just because you’re not happy with your plan. If not, it may be time to find a real dental home, one that will do honest work for honest pay, and not play games with your health, your money, and your insurance company’s money.

What is the best dental insurance?

You are fortunate if your dental insurance policy has just one or more of the following features:

  1. You pay nothing extra per month for your dental plan.
  2.  You can go to any dentist you want.
  3.  You have no maximum dollar limit.
  4.  Major services are paid for at 80%.

If none of these apply, then your insurance probably costs you more than you receive from it. My suggestion would be to opt out of your dental plan and let yourself get paid a little more per month instead. Then if you simply must be on a plan, many dentists offer their own form of in-house insurance, where you pre-pay for your preventive care each year and in return you get a percentage discount for any other services you’ll need. It’s sort of like a twice-yearly gym membership, with reduced pricing for personal training sessions.

I still wish someone else would pay for my teeth.

Me too! Wouldn’t that be great? But there came a point in my life where my parent’s money stopped being my dental insurance. I had to accept that my teeth were my responsibility, and that I would have to find a way to help them stay as natural as possible. Even with a career working daily in a dental practice, I’ve always had to pay out of pocket for the level of dental care that I value. One cleaning, checkup, and set of X-rays per year costs about $150 in my area, which isn’t worth jumping through insurance hoops for.

In the meantime, if you don’t have someone else paying for your teeth (like a rich relative or a great insurance plan), go to the best dentist you can find, explain that you’re done with “what insurance will cover” and ask them to treat you like a human being instead. You might just be surprised at the quality of care you receive for the cost.

And none of us, on either side of the equation, will miss the dental insurance game, not one bit.

Should dental hygienists give shots?

March 15, 2017 By Trish Walraven 13 Comments

healthyteeth212

When people talk about what they hate most about going to the dentist, they’re usually talking about the needle. I mean, who in their right mind would ever consent to allowing another person to give a shot in a place that has as many nerve endings as our tongues, lips and cheeks? Shots in the mouth are pretty dang scary. And when you’re trying to calm down and prepare yourself for an injection, it’s almost worse than trying to relax for the air-burst thingy they do at the optometrist’s office when you’re getting your eye pressure checked.

And yet, anyone who has had significant dental treatment performed has allowed someone to inject their mouth with a needle, right? We’ve all accepted the fact that shots are so much better than the actual thing that we hate about going to the dentist.

Pain. Pain is what we really hate.

And shots? They make pain go bye-bye. No shot? You’re all-knowing (in a very bad way) about every little thing that is getting fixed in your mouth.

But you already realize this unpleasant truth. What you might not know is that there’s a stink in Texas right now about who can give shots at the dentist’s office and who can’t. Here’s a little backstory: Dentists go to college for 6-8 years to learn all the things they need to do in order to be dentists. Dental hygienists are in college for 2-4 years to learn everything they need to learn in order to be dental hygienists. In states that allow dental hygienists to give shots, their anesthesia education follows the same curriculum as dentists. These states also test dentists and hygienists to make sure that they are qualified to give shots before granting their licenses.

In Texas and five other states, this is not true. A dental hygienist’s education in regards to anesthetic delivery is considered inferior, and therefore, allowing hygienists to stick a needle in a patient’s mouth allegedly places the public in unnecessary danger.

On this map, you’ll see red states, with years next to their abbreviations. These are the states that allow hygienists to give shots, along with the dates when administration and licensing first became available. [edit: See image at update at the bottom of this article – this was amended to 47 states in 2023]

Do I think that Texas should allow dental hygienists to give shots just because “everyone else is doing it?” No. We tried being our own country once, and if we still were our own country we wouldn’t care one tiddly bit what was going on in the US.

The reason that Texas should allow dental hygienists to give shots is simple:

We are tired of hurting people.

The alternative is to ask the dentists we work with to leave a hole in their schedule so they can come give a shot for us. And come anesthetize again if the first time didn’t work. And again if our patient is still in pain.

Here in Texas, hygienists learn to say “I’m Sorry” a lot to our patients, instead of continuing to interrupt our dentists.

Thankfully, most of our patients don’t need shots. Those who come regularly have healthy mouths and their visits with the dental hygienist are preventive in nature, comfortable, maybe even relaxing. But take a person who has been scared to go to the dentist for a while and they’ve noticed that their gums bleed when they brush. There are sores in their gums, and guess what? The treatment it takes to heal up those sores can hurt! Hygienists in all states are highly trained to provide this deeper therapy – it’s what we “really” do. And if there are obstacles to providing this treatment painlessly, well, it’s either not going to be painless, or else the treatment won’t be as thorough as it would have been if it would have been if the patient had gotten completely numb.

Last week’s hearing of the Texas Senate Committee on Health and Human services highlighted the stances of those both in favor and against granting dental hygienists the permission to deliver local anesthesia, in other words “give shots.” The original video was 2 1/2 hours – I’ve shortened it down to a little under 40 minutes of testimony only about this bill, edited out all the procedural or repetitive bits, and left the juiciest parts behind.

Full video of the archived meeting: http://tlcsenate.granicus.com/MediaPlayer.php?view_id=42&clip_id=11813

Here are my bullet points, yes… •Bullet •Points for this committee meeting:

• The map handed out in the chamber is the same one you see in this article (feel free to scroll up and follow along).

• The bill is permissive, not mandatory. If a dentist does not want to allow a hygienist in their office to give shots, they can’t. Furthermore, dentists must be present in the office for hygienists to administer anesthetics.

• No evidence of harm is presented in any testimony. Scroll to 18:45 where you’ll see Dr. Scott Dowell testifying for the Texas Society of Periodontists against this bill. His admission of the relative danger of local anesthesia is…interesting.

• The Texas Dental Association states that they opposed to this bill due to patient safety because they feel that it lowers the education standard and it’s only about expanding dental hygienist’s scope of practice, possibly to open the door to independent practice by hygienists.

• Dr. Matthew Roberts, who represented the Texas Dental Association, seemed surprised to learn that physicians are legally allowed to delegate the duty of administering anesthesia shots to even medical assistants in their practice when this is brought up in the meeting.

• There are 9000 members of the Texas Dental Association, but in a poll, 53% of the members were actually in favor of hygienists giving shots.

• The amount of training dentists receive to legally put patients “to sleep” is less than the training hygienists receive in order to be legal to give shots.

If you’re not convinced by this video, then you didn’t actually watch it (my opinion, sheesh!). But if you did watch it and still feel like hygienists are unqualified to give shots, your voice is very important to us right now. Maybe there are more problems with hygienists using needles, maybe there are negative reports that haven’t been correlated properly. Do you have concerns? Post them here in the comments below. I’m serious – if there is a compelling reason that is being hidden from the public and even from hygienists, we all deserve to know the truth.

At this point, though, if the day ever comes when I’ll be able to give my patients shots, it will be like someone trusted me with the most delicate equipment available in the Compassion Toolbox. It is a precious gift to be able to deliver painless dental care, and for those in the caring business (which most of medicine is, if you think about it) sometimes it’s the best gift we can give to others.

Yuck, ick, too late, the mush landed. Bottom line? Please don’t hate me if I ever get to stick you with a needle.

Trish Walraven RDH, BSDH is a dental hygienist who lives in the suburbs of Dallas/Fort Worth. She longs for the day when she can drop a couple grand of her own money and leave her family to take a week-long college course, just so she can sit for an anxiety-provoking board exam that will grant her the license to poke a shot in places that no one wants poked. Goals, man. Goals.

UPDATE 4/5/2017:   The April newsletter from the TSBDE states that SB 430, which would authorize dental hygienists to administer local anesthetic was heard in the Senate Health and Human Services Committee on March 8, 2017.  The committee considered testimony both for and against the legislation.  The bill was voted out of the Health and Human Services Committee on April 5, 2017 with some changes.  The change is that only infiltration administration would be permitted.  The bill is now waiting to be scheduled to be heard by the full Senate.

UPDATE 5/25/2023:

It’s been six years since the original article above was posted; however, today I received the following information:

“After almost a year of collaboration between TDHA [Texas Dental Hygienists’ Association] and TDA [Texas Dental Association], legislation passed today through the Texas Senate that would allow Texas dental hygienists to administer local infiltration anesthesia.

The last step is for Governor Abbott to approve and sign the bill which would then become law. After the legislation is signed by the Governor, the Texas State Board of Dental Examiners will be tasked to write specific rules and educational requirements that will align with the intent of the legislation. This is a lengthy process that can take up to a year. The rules will then need final approval from the Governor’s Office.

Please note – this legislation allows dental hygienists to administer local anesthesia under the direct supervision of a dentist via infiltration only to patients who are over the age of 18.”

Here’s the thing: this was also the biggest bone of contention even in the 80’s and 90’s for the majority of Texas dental hygienists. For over 30 years we have been arguing for this option! That’s pretty much the scope of an entire career. Enough said – all you 50+ year olds who’ve been waiting for this day? See y’all back in college soon!

About

DentalBuzz explores rising trends in dentistry with its own slant. The speed at which new products and ideas enter the dental field can often outpace our ability to understand just exactly the direction in which we are heading. But somehow, by being a little less serious about dentistry and dental care, we might get closer to making sense of it all.

So yeah, a tongue-in-cheek pun would fit really nicely here, but that would be in bad taste. Never mind, it just happened anyways. Stop reading sidebars already and click on some content instead.
