Who owns your dentist?

The sign outside says a person's name — Dr. Somebody, Family Dentistry. You've been going for years. But if you asked who actually owns the practice, the honest answer might be a private-equity fund headquartered a thousand miles away, one you've never heard of, that also owns a few hundred other "family" practices under a few dozen different names.

This is the first piece in a series we're calling Who owns your…? We're starting with dentists because it's the clearest, best-documented case of a pattern that's now spreading to veterinarians, home services, and beyond.

The quiet machine: DSOs

The vehicle is a Dental Support Organization, or DSO. In theory it's benign: an outside company handles a practice's "non-clinical" side — billing, marketing, HR, purchasing — so the dentist can focus on teeth. The American Dental Association defines it as exactly that, and plenty of DSOs are perfectly reasonable arrangements a dentist chose.

But the DSO is also the wrapper private equity uses to own dentistry without appearing to. In most states a non-dentist can't own a dental practice outright, so the fund owns the DSO, the DSO "supports" the practices, and the dentist's name stays on the door. From the sidewalk, nothing changed.

How far it's gone

Not a fringe thing. Per the ADA's Health Policy Institute, the share of U.S. dentists affiliated with a DSO climbed from about 9% in 2017 to 13% in 2022, and the ADA's more recent counts put it near 16% — with more than a quarter of dentists in their first ten years out of school now affiliated. The next generation of dentistry is being organized this way as it starts.

The single biggest player shows the scale. Heartland Dental, the largest DSO in the country, supports roughly 1,900 practices across 39 states and D.C. — and since 2018 it's been majority-owned by the private-equity giant KKR. It is one of a dozen dental roll-ups we track, alongside names like Smile Brands and Bright Now! Dental (owned by Gryphon Investors) and MB2 Dental. You can see the full list of dental PE firms we monitor.

Why it can matter at the chair

Ownership would be an abstraction if it stopped at the paperwork. Sometimes it doesn't. When a practice has to hit a fund's growth targets, the pressure can reach the exam room.

The starkest documented case: in 2018 the dental-management company Benevis and its Kool Smiles clinics paid $23.9 million to settle Justice Department allegations that they billed Medicaid for medically unnecessary procedures on children — baby root canals, extractions, and steel crowns — while, per the DOJ, pressuring dentists to hit production goals, disciplining "unproductive" ones and paying cash bonuses for revenue generated. That's not every DSO, and it's an extreme case. But it's exactly the failure mode people worry about when the person setting the numbers doesn't sit in the chair.

Where the picture gets honestly fuzzy

We want to be careful here, because the loud version of this story overreaches.

DSO-affiliated does not mean PE-owned, and neither means bad. Many DSOs aren't private-equity-backed at all. Many dentists join one by choice and keep full clinical control. A corporate-owned practice can have an excellent, ethical dentist — plenty do. The problem isn't a slur on anyone's dentist; it's that the ownership is invisible to you, and you can't weigh what you can't see.

And we can't always tell you, either. These structures are deliberately opaque. Our screen catches the known roll-up brands; it will miss a quiet local practice that was bought last year and hasn't surfaced in any list. When we're not sure, we don't guess.

How to see it — and our part

You can do a little of this yourself: search the practice's name plus "DSO" or "acquired," or look at the fine print on their site for a management company. If several "independent" practices in your town share one billing address or one faceless parent, that's the tell.

Our part is to keep the map honest. Free Range lists 4,974 independent dentists we have no reason to believe are owned by a fund, and we screen every one against the roll-up brands above. It's not perfect, for the reasons we just admitted. But when you want a dentist whose only stakeholder is the person holding the drill, it's a place to start.
