This week an essay titled “Do dentists know what they’re doing?” burned through Hacker News to 720 points and 522 comments, which is the internet’s way of saying that one out of every three readers was angry enough to type something. The piece asks whether routine dentistry is mostly evidence-based practice or an elaborate upsell with a drill. It’s a fair question, and the discussion underneath it produced the usual two camps: the people who think their dentist is inventing cavities, and the people who think questioning a licensed professional is a symptom of terminal online brain.

Both camps are arguing about the wrong thing. The actual fight over dentistry in 2026 is being conducted in state legislatures and federal courtrooms, and it is not a fight about whether your dentist is a crook. It is a fight about who is allowed to see the numbers.

The Guild Is the Reformer Now

If you’re right-of-center, your reflex on professional associations is that they are cartels with nicer letterhead — licensing boards that exist to keep the supply of practitioners low and the fees high. Usually that reflex is well-earned. Here it isn’t, or at least not this year.

The American Dental Association says it backed the passage of more than 30 new laws in 16 states during the 2026 legislative sessions, aimed at things like dental loss ratios, network leasing, virtual credit card fees, and non-covered services. Read that list again. Those are all disclosures — rules forcing insurers to say where the premium dollar goes and to stop quietly leasing their networks to third parties who then decide whether your crown is covered. The ADA also backed S. 4370, the Primary Care Team Education Centers Act, to expand hygienist and assistant training.

On July 1, a proposed antitrust class action was filed in federal court in Washington — Henneberg v. Delta Dental of Washington, No. 26-cv-2185 — accusing the insurer and its affiliates of violating antitrust law in how they reimburse. Whatever you think of that suit’s merits, notice the posture: the professional association and its allies are on the side of the patient learning what the price actually is. The payer is on the side of the price staying a private matter.

That should make free-market health reformers uncomfortable, because their standard move — attack the guild, deregulate scope of practice — doesn’t address any of this. Letting a hygienist drill a cavity does not tell you whether the cavity needed drilling.

Consolidation, Not Credentialing, Is What Changed

Here is what actually changed in the last decade: ownership. On October 2, Heartland Dental announced it had brought Foundation Dental Partners into its supported network — the latest slice of a consolidation wave that has been quietly converting independent practices into units of dental support organizations. In May, the California attorney general reached a settlement with Aspen Dental over corporate-practice claims, a reminder that the corporate structure of a dental office is now contested legal territory in the biggest state in the union.

Why does that matter more than credentialing? Because in a DSO-affiliated office, the person deciding what treatment your mouth needs may not own the practice, may not set the fees, and is very plausibly measured on production. A hygienist at a DSO-affiliated office outside Phoenix put it to me bluntly in a Slack message after a Thursday close: “We know what the schedule wants. The schedule wants crowns.” I’d rather not have to take her word for it. But there is no public data that would let me check.

Meanwhile the same offices are accumulating the same risks everyone else in health care is. Sartell, Minn.-based Persona Dental reported a breach affecting 3,386 patients to the federal breach portal on September 10 — small by hospital standards, and exactly the size of operation that has no compliance department.

Nobody Publishes Whether the Filling Held

Here is the missing variable in the entire “do dentists know what they’re doing” debate: nobody tracks outcomes. Your insurer knows what code was billed. Your dentist knows what the X-ray looked like that day. Five years later, when the filling fails, no one is recording that — and nobody is publishing the rate at which it happens, by practice, in a form a patient could consult.

We do have the litigation layer. Becker’s Dental Review recently tallied four dental lawsuit settlements totaling $13.5 million. That’s the system working, in the sense that a smoke detector works: it tells you something burned.

What the profession’s own internal argument shows is that the clinical questions are genuinely open. A periodontist writing a rebuttal to the original essay spent his space on X-rays, routine cleanings, and the real question of infective endocarditis risk — an argument about whether the procedure helps. The public argument is about whether the procedure gets paid for. Those are different conversations, and only one of them is being legislated.

So here’s the uncomfortable part for conservatives who want price signals and consumer choice in dentistry: price signals require knowing which dentist’s work holds up. The only institutions sitting on that data at scale are the insurers — the ones the ADA is currently suing and lobbying against. Deregulating the licenses while leaving the ledger closed gets you more consolidation, more production quotas, and the same 522 comments next year.

The person with the least information in this entire arrangement is you, in the chair, with your mouth open.
