In California, only licensed dentists can own a dental practice in most circumstances. The state treats dentistry as a licensed profession where ownership and clinical control must remain in the hands of people who hold a valid dental license. There are a handful of narrow exceptions for nonprofits, certain clinics, and temporary estate situations, but the general rule is clear: if you’re not a licensed dentist, you cannot own a for-profit dental practice in California.
Solo Practices and Partnerships
A licensed dentist can own a practice as a sole proprietor or form a partnership with other licensed dentists. If you practice under your own name (for example, “Dr. Terry Jones, General Dentistry”), no special permit is needed beyond your dental license. If you want to operate under a different name, like “Sunset Family Dental,” you’ll need a Fictitious Name Permit from the Dental Board of California. That permit requires that the practice location be owned or leased by the applicant, and that the practice conducted there be wholly owned and entirely controlled by the permit holder.
Fictitious Name Permits are tied to a specific address and ownership structure. If you move locations or change from a sole proprietorship to a corporation, you need to file a new application.
Dental Corporations
California allows dentists to form professional corporations under the Moscone-Knox Professional Corporation Act. A dental corporation can render professional services, but every director, shareholder, and officer must be a licensed person as defined by the Act. Under California regulations, shares of a dental corporation may be owned only by licensed dentists or by another dental corporation.
The dental corporation statute also recognizes that certain other licensed professionals may be involved in the corporation’s operations. The law specifically names physicians and surgeons, dental assistants, registered dental assistants (including those in extended functions), registered dental hygienists (including those in extended functions), and registered dental hygienists in alternative practice as people who can render professional services through the corporation. However, this does not mean these professionals can be majority shareholders. The ownership structure must comply with both the Moscone-Knox Act and dental-specific regulations, which keep share ownership restricted to licensed dentists.
If you’re forming a dental corporation, you’ll also need to file Articles of Incorporation for a professional corporation with the Secretary of State and provide a copy to the Dental Board when applying for a Fictitious Name Permit.
Why Non-Dentists Cannot Own a Practice
California’s Business and Professions Code defines the practice of dentistry broadly. Under Section 1625, owning or managing a place where dental operations are performed can itself constitute practicing dentistry. This means a non-dentist investor who owns a dental office could be considered to be illegally practicing dentistry, even if they never touch a patient.
This is the core legal barrier. Unlike some states that have loosened restrictions, California maintains that ownership and clinical independence go hand in hand. The law is designed to prevent outside investors, private equity firms, or business entities from controlling dental practices and potentially influencing treatment decisions for financial reasons.
The MSO Workaround and Its Limits
Some non-dentist investors have used Management Service Organizations (MSOs) to participate in dental practices indirectly. In this arrangement, a licensed dentist technically owns the practice while the MSO handles billing, marketing, staffing, and other business functions. The MSO profits from management fees rather than from owning the practice itself.
California has been tightening the rules around these structures. SB 351, a law taking effect before January 2026, explicitly prohibits non-physician investors from exercising any control over clinical decision-making, patient care, treatment recommendations, or access to medical records. The law also bans common contract clauses in private equity-backed MSO deals, including non-compete agreements that restrict dentists after they leave and gag clauses that prevent providers from criticizing business practices or care quality. Any direct or indirect interference with a dentist’s professional judgment may be deemed unlawful corporate control.
MSOs remain legal in California, but only when they stay strictly on the business side and leave all clinical authority with the licensed dentist-owner.
Nonprofit and Public Clinic Exceptions
California carves out specific exceptions for certain types of organizations that can employ dentists and charge for their services without being considered to be practicing dentistry. These include:
- Licensed primary care clinics operating under the Health and Safety Code
- Exempt primary care clinics that meet specific statutory criteria
- Clinics owned or operated by public hospitals or health systems
- Hospital-owned clinics that hold the primary contract with a county government for indigent care
Tax-exempt nonprofit corporations also get a specific exception. A nonprofit that is supported substantially by donations, bequests, gifts, grants, government funds, or charitable contributions can own and manage a location where dental services are performed. But there are conditions: the entity must obtain approval from the Dental Board, it cannot interfere with or direct the professional judgment of licensed staff, and all licensees working there must comply with state dental regulations.
Community health centers operating as nonprofits fall under this framework. They can employ dentists directly and bill for services, which is how many low-income dental programs in California function.
What Happens When a Dentist Dies or Becomes Incapacitated
California law provides a 12-month grace period when a dentist-owner dies or becomes incapacitated. During that window, certain people can continue operating the practice, employing dental staff, and billing for services without holding a dental license themselves. Those people include the legal guardian or conservator of an incapacitated dentist, the executor or administrator of a deceased dentist’s estate, and the trustee of a trust that was set up specifically to handle the practice in case of death or incapacity.
The trust exception is narrowly written. It applies only to trusts whose assets consist solely of the dental practice and that were created for the specific purpose of disposing of the practice if the dentist could no longer run it. After the 12-month period ends, the practice must be sold to a licensed dentist or dental corporation, or it must close.
Ownership Structures at a Glance
- Sole proprietorship: One licensed dentist owns and controls the practice
- Partnership: Two or more licensed dentists share ownership
- Professional corporation: Shares held only by licensed dentists, formed under the Moscone-Knox Act
- Nonprofit corporation: Must be tax-exempt, charity-supported, and approved by the Dental Board
- Public or licensed clinics: Specific clinic types defined in the Health and Safety Code
- Estate or trust: Temporary ownership for up to 12 months following a dentist’s death or incapacity
Outside of these categories, there is no legal path for a non-dentist individual, a general business corporation, or a private equity fund to directly own a dental practice in California. The state’s framework is one of the more restrictive in the country, and recent legislation signals that enforcement is moving toward tighter scrutiny of indirect ownership arrangements as well.
