I'm not a dentist but run an oral health/microbiome testing company, so I've been "in the industry" for some time as a non-incumbent and I've had the opportunity to connect with almost every stakeholder (patients, providers/dentists, hygienists, and payers) in dental care. My background is in genomics/sequencing so most of my experience pre-company was on the systemic health/medical side.

A lot of the problems are the result of misaligned incentives. While it's applicable to almost all of healthcare, it's especially prevalent in dental. Providing high-level what I've seen with the understanding that I am talking about the worst outcomes of our care model and certainly not hitting all of the problems. That said, I have met many more dentists who genuinely care about their patients than those who don't - and I truly believe that is the norm.

*Payers* Dental insurance is glorified discounting. Medical insurance provides annual out-of-pocket maximums (deductibles) where anything you pay beyond that is covered by the insurer. Dental insurance is the opposite. There is an annual maximum the insurer will cover (usually ~$1500) and anything beyond that is covered by the patient. In both cases there are some covered services (medical: checkups, some tests, etc. dental: X-rays, cleanings, etc.) but the second you have something even marginally serious your insurance SHOULD kick in. The problem with dental is that it doesn't. I've spoken with people that had to defer necessary procedures for a year because insurance could only cover half - so 1/2 this year and 1/2 next year.

The problem with this model is that while medical insurance is (theoretically) more incentivized to keep costs low since they will have to pay for major care, dental insurance has a natural ceiling. Yes, if you need $5k of dental work the insurer "suffers" - but it's maxed out for whatever your coverage limit is. There's not a severe financial downside to extensive care.

*Providers* Complimentary to the model of dental insurance is a fee-for-service (FFS) model for care. What this means is that providers are paid based on services. In other words, a provider makes more money doing a cavity filling than not having to do one because they kept you healthy.

The extreme opposite would be a model where a dentist was financially penalized every time you needed a filling - you can imagine how the relationship and role of the provider would change.

Something that gets overlooked, but is important to call out, is that the system for becoming a dentist doesn't help. There are 4 years of dental school. When you graduate, you're likely $XXX,XXX in debt. On top of that, private practice is still extremely prevalent in dental care - so add another $XXX,XXX in debt. Plus the cost of the equipment you need. This isn't an excuse, but its a reality for many dentists. When you combine massive debt and a care model that prioritizes paying for procedures the result is what we see today.

The other problem is that this misalignment means providers have to make personal/ethical choices around care. Sometimes those choices mean performing unnecessary procedures on patients. Sometimes it's the opposite, and the provider takes a personal hit on revenue. So you end up with 5 second-opinions, none of which line up to the others. A provider should not have to choose - or eve consider - ethical responsibility to patients vs. financial stability.

*Patients* We - patients - get shafted in dental care. Our system is incentivized to reactively treat disease over maintaining good health. On average we pay [40% of dental expenditures out of pocket](https://www.carequest.org/system/files/CareQuest-Institute-B...). That's ~4x more than the average for all other healthcare services.

We're left to navigate oral care on our own. Of course you're skeptical when a dentist says you need 10 fillings - they're incentivized to perform the procedures. Would you be as skeptical if you knew the dentist was getting charged $50 for every filling they had to do? Do you think the care model would change if dental insurers suddenly had to pay for your $10k dental procedure instead of you?

Cavities and gum disease - largely preventable conditions - are the most prevalent diseases on the planet. And we're not talking about some complex, mysterious disease. These are microbial infections. We have tools to detect them early and interventions that work (at least work well enough to make a major dent). Misaligned incentives don't motivate anyone to adopt these technologies or encourage preventive care.

Anyway, that's my rant. There are lots of things I didn't cover but I have to get back to work. Linking [my company here](https://www.bristlehealth.com/) to minimize self-promoting but provide some more info.

Ah this article put the finger on why I don't trust my 'new dentist': The operation is just too slick from a business POV. As someone familiar with SaaS or in general this kind of recurring business model, you can sense all the little operational policies and procedures designed to increase your LTV. It's a well-oiled machine. Without fail, the hygienist recommends cleaning not once every 12 months or even every 6 mo…

Yup. In fact, a great hack is to go to an inexperienced dentist instead of an experienced one for routine work. The reason is that dentists who are fresh out of school are competent enough to do basic cleanings and checkups. But they haven't yet had time to accrete the expensive habits, and the little business optimizations that feed them, that highly-paid professionals often develop. I generally switch dentists every five years or so, and find that cadence works nicely.

A compelling book on tooth care is Kiss Your Dentist Goodbye by Ellie Phillips. It advocates for: - Using flouride toothpaste. - Using a combo of bad-bacteria-killing mouthwash and flouride mouthwash (especially before bed). - Eating or finishing meals with tooth-protective foods. - Chewing xylitol [0] gum or mints. Xylitol is a sugar-replacement (with a lower insulin response) found in plants . I think Epic Dental h…

Daily mouthwash is a horrible idea. Mouthwash contains Corsodyl which has been shown to increase blood pressure. Regularly blasting any part of your body with a harsh antiseptic is probably a bad idea. It took us decades to realize that antibiotics messes up our gut floura, I'm sure we'll see similar consequence for mouth bacteria with mouthwash.

Also, mouthwash containing alcohol increases the risk of oral cancer. I have had multiple dentists advise against mouthwash.

Throwaway because I run a large dental software company. Dentistry is practiced as a business focused on maximizing revenue. Dentists are routinely coached to deploy sales tactics to increase their treatment acceptance beyond what is needed. If you walk into a dental office, you need to protect yourself from being abused. A second opinion unfortunately puts you in the same position, but now with a new dentist who wil…

I've told this story here before, but I grew up with very health-illiterate parents, who were very "old school" in the sense that if anyone in a white coat said something, it was gospel. Doctor, dentist, nurse, whatever (curiously they had and still have extremely negative opinions of medical paraprofessionals like PAs and NPs). Anyway, I was around 15 or 16 and had always had perfect dental checkups. One day I had a…

> curiously they had and still have extremely negative opinions of medical paraprofessionals like PAs and NPs

This isn't entirely unfounded. There are real concerns over replacing MDs with mid-levels with much less training. The AMA is significantly to blame for the switch, but as a general rule I won't see PA/NPs for anything beyond prescription refills or something like that.

> ...whose practice was a convenient 10-minute walk from Mitchell’s home, Not a good criteria for choosing a dentist. My dentist is a 4 hour drive away.

Not a good criteria for choosing a dentist. Sure it is - it is about as good as anything else you might wind up with, especially if you don't know anyone in the area, don't have a dentist for whatever reason, or simply cannot afford to travel such distances. And to be fair, you won't realistically know that someone is selling you treatments you do not need and you can always decline if you suspect such a thing. I'm g…

Especially if you get into procedures like crowns you are probably talking multiple visits. Mind you, they don't need to be next door. I kept the dentist I had when I was working 45 minutes away because I like them and it's not that much of an inconvenience to drive up there.

Near the beginning of the pandemic, I had a pretty bad toothache spring up out of basically nowhere. Bad enough that sleeping was difficult and eating was impossible. I went to see a dental surgeon (I forget the proper name for this) and he told me I needed a root canal, and backed it up with X-rays. It made sense, I had trouble with this tooth before and a previous dentist told me that a root canal and crown on this…

Not asking directly to you, but in these cases is there (depending of the country) a way to make this kind of malpractice stop ? Organization to which to report the dentist ?

I would also add electric toothbrush to this list. This has been transformative for me. I wish I could hand one to my 6 year old self. They are cheap and you can use them in the shower.

Same for me. I used to have cavities nearly every time I went to the dentist, and none after switching to electric brushing a decade ago.

Many argue that pushing flouride on the public is an outright scam and lie. Fluoride is a known toxic substance that damages the body and can compromise one's health. It was being dumped in the water by factories, and the industry helped pull off a con by paying for studies to show that their industrial waste was actually "good" for people. The public fell for it, and here we are today. All these people drinking in and brushing with the so-called miracle of flouride, yet so many cavities (and other health problems).
