Who can own a dental practice? Dentists, hygienists, DSOs and non-dentists

Corporate practice of dentistry is the shorthand for state rules tying ownership and control of a dental practice to a dental license.

In three of the four statutes below, the mechanism is a definition: the practice act's list of what counts as “practicing dentistry” reaches business activities, not just clinical ones.

Florida's is a standalone bar.

California's version covers managing the place, not just treating in it: under Business and Professions Code 1625(e), a person who “manages or conducts as manager, proprietor, conductor, lessor, or otherwise, a place where dental operations are performed” is practicing dentistry.

California then opens a narrow shareholder window: under Corporations Code 13401.5, certain non-dentist licensees — physicians and surgeons, dental assistants, RDAs, RDAEFs, RDHs, RDHEFs and RDHAPs — may hold shares in a designated dental corporation so long as the sum of all shares owned by those licensed persons does not exceed 49 percent of the total.

Texas writes the idea as an employment test: under Occupations Code 251.003(a)(4), a person practices dentistry if the person “owns, maintains, or operates an office or place of business in which the person employs or engages under any type of contract another person to practice dentistry.”

Florida states the bar outright: under Florida Statute 466.0285(1), no person other than a Florida-licensed dentist, and no entity other than a professional corporation or LLC composed of dentists, may employ a dentist or dental hygienist in the operation of a dental office, control the use of dental equipment during care, or interfere with a dentist's clinical judgment.

Violating the statute is a third-degree felony, and a contract made in violation is void.

Colorado reaches ownership through its “proprietor” definition: a proprietor of a place where dental services are performed is practicing dentistry under Colorado Revised Statutes section 12-220-305(1)(b), and “proprietor” includes any person who employs dentists, dental therapists, dental hygienists or dental assistants in the operation of a dental office (section 12-220-104(13)(a)).

Section 12-220-305(1)(b) carves out dental therapists, hygienists and assistants performing tasks consistent with section 12-220-501 — the hook the hygiene section below hangs on.

A word on coverage: these four states are where this page's research reached at the statute level.

It is not a count of the states with such rules, and this page takes no position on the states it did not review — exceptions and entity rules vary and were not counted.

Structuring any purchase, partnership or management arrangement starts with your own state's practice act and a healthcare attorney.

A dental support organization is the structure the ownership rules produced.

The Association of Dental Support Organizations describes DSOs as contracting with dental practices to provide business management and support, including non-clinical operations: facility maintenance, supply procurement, human resources, compliance, accounting and marketing.

ADA HPI counts a practice as DSO-affiliated if an outside entity manages some or all of its non-clinical functions such as billing, marketing or human resources.

By ADA HPI's count, 16% of U.S. dentists were affiliated with a DSO as of 2024.

The career-stage split is steeper: 26.5% of dentists up to 10 years out of dental school, versus 14.4% of those 11–25 years out and 9.1% of those more than 25 years out.

The structure is the compliance answer to the statutes above: the clinical practice stays with the licensed dentist — in Florida, only a licensed dentist or a professional corporation or LLC composed of dentists may employ a dentist or hygienist in a dental office — and the DSO contracts to run the business functions around it.

Florida also shows how specific the line gets: under Florida Statute 466.0285(2), a non-dentist may not control, through any arrangement with a dentist, the selection of treatment, patient records, pricing, credit, refund and advertising policies, or decisions about office personnel and hours of practice.

And any arrangement in which a non-dentist provides a dentist with dental equipment or materials must state that the dentist keeps complete care, custody and control of the equipment or practice.

Even the charts can stay clinical-side: Texas board rule 22 TAC 108.8 says dental records are the sole property of the dentist who performs the service, though ownership of original dental records may be transferred as the rule provides.

In Georgia, licensing stays with people, too.

The Georgia Board of Dentistry states that it does not license dental service organizations, clinics, offices or any other non-person entity — the license belongs to people.

How any given DSO or MSO model complies in a given state was beyond this page's research — the open questions run past Florida's control limits.

If a DSO in your market is the reason your chairs sit empty, that is a recruiting problem more than a structural one: our guide to competing with DSOs for staff covers the hiring side.

“Can a dental hygienist buy a dental practice” is two questions.

Buying a general practice that employs dentists runs into the same ownership statutes any non-dentist faces; owning a dental hygiene practice is a different, licensed path that exists where state law creates it.

Colorado has the broadest version in this page's sources.

Its practice act recognizes “unsupervised dental hygiene”: a person who is not licensed to practice dentistry may scale and root plane, apply fluorides and sealants, and gather patient records and radiographic surveys for dental hygiene treatment planning (Colorado Revised Statutes section 12-220-503(1)).

ADHA's February 2025 direct access chart adds that Colorado requires no dentist authorization or supervision for most hygiene services, and that a hygienist may own a dental hygiene practice.

New Mexico appears in the same chart: a collaborative-practice hygienist can practice in any setting under a collaborative agreement and can own or manage a collaborative dental hygiene practice.

That entry is a chart summary — the underlying state rule was not reviewed here — so confirm the current rule with the state before relying on it.

California's path is a credential: a registered dental hygienist in alternative practice (RDHAP) may work as an employee of a dentist or of another RDHAP, as an independent contractor, or as the sole proprietor of an alternative dental hygiene practice, among other settings (Business and Professions Code 1925).

An RDHAP must also provide the Dental Hygiene Board documentation of an existing relationship with at least one dentist for referral, consultation and emergency services (Business and Professions Code 1930).

Maine licenses independent practice dental hygienists, whose duties include performing all procedures necessary for a complete prophylaxis — including scaling and root planing and periodontal maintenance — applying sealants and exposing radiographs, among others (Maine Revised Statutes Title 32, section 18375(1)).

Before a first visit, the hygienist must obtain the patient's written acknowledgment that they are not a dentist and the service is not restorative care, and give a written plan for referral to a dentist (Title 32, section 18375(2)).

Maine's paperwork says what this path is: a hygiene practice, not a dental practice.

Dental therapists are the newest group an owner might build a role around, and the settings rules bind tightly.

A Minnesota dental therapist is limited to primarily practicing in settings that serve low-income, uninsured and underserved patients or in a dental health professional shortage area (Minnesota Statutes 150A.105, subdivision 2), and must sign a written collaborative management agreement with a Minnesota-licensed dentist before providing services — a collaborating dentist is limited to agreements with no more than five dental therapists or advanced dental therapists at any one time (subdivision 3).

In Arizona, dental therapists may not dispense or administer narcotic drugs and may not independently bill for services to any individual or third-party payor (Arizona Revised Statutes 32-1276.03(C)).

Authorization, settings and supervision limits are state-specific — Minnesota's shortage-area and Arizona's billing limits are the examples this page's sources reach.

Never assume one state's rules travel.

What the research did not find: any state rule on dental therapists owning practices.

Denturists hold a path of their own in Washington: the “practice of denturism” by a licensed denturist includes taking impressions and furnishing or supplying a denture directly to a person or advising the use of a denture, and maintaining a facility for the same (RCW 18.30.010).

License categories are the map: Maine's Board of Dental Practice licenses dentists, dental hygienists, dental radiographers, dental therapists, denturists and expanded function dental assistants, and issues sedation permits — who can stand alone in a state starts with the board's categories.

The table collects the statute-level sources behind this page, state by state — a research footprint, not a census.

A state missing from it has neither been found to allow nor to bar non-dentist ownership.

If you employ clinical staff, the ownership rules decide who the employer of record can be.

In Florida, only a licensed dentist — or a professional corporation or LLC composed of dentists — may employ a dentist or dental hygienist in a dental office.

In Colorado, employing dentists, therapists, hygienists or assistants in a dental office makes a person a “proprietor” — and being a proprietor is practicing dentistry — except as provided in sections 12-220-305 and 12-220-501, the carve-out for therapists, hygienists and assistants covered above.

Whoever signs the offer letters has to fit the structure your state allows.

If you are buying rather than building, make the ownership question the first gate: confirm who may legally own the practice in your state, and in what entity, before you price the deal.

Our guide to how to buy a dental practice walks the process; this page is the compliance check ahead of it.

If you are starting fresh, the same gate comes before the lease: starting a practice as an employer covers the build, the staffing plan and the first hires — all of which assume an owner your state recognizes.

If the owner path is yours — or you are hiring someone who wants it — the dental practice owner career guide covers the role from the owner's side.

If you hire dental therapists where your state authorizes them, fold the settings and agreement limits into the plan — the hiring a dental therapist guide covers screening and supervision.

And if you manage inside a DSO, know which decisions cannot move to the business side.

Florida is the clearest example: a non-dentist may not control, through any arrangement with a dentist, decisions relating to office personnel and hours of practice.

Mapping your state's version of that line, with your dental board and a healthcare attorney, is most of the compliance work.
