Dental Practice Resources in California

California is the strictest state on this list in two directions at once. Its radiation inspectors arrive with a specific list of records they expect you to produce, and its employment law voids non-compete agreements outright and gives employees a cause of action if you try to enforce one. If you are moving a practice into California from anywhere else, both of those will change how you operate.

Who regulates what

License renewal and continuing education

The Dental Board publishes 50 CE units per two-year renewal cycle for a standard dentist license, and specifies that courses must be taken within the most recent two-year license or permit renewal period. Banking hours from an earlier cycle does not work.

Four courses are mandatory:

The Board-approved provider requirement is where people waste money. A general infection control webinar from a national vendor may not count if the vendor is not a Board-approved provider for that specific California course. Check the provider status before you register, not after.

The board's page does not state how often each mandatory course must be repeated, so confirm the repeat interval with the board directly. Do not assume all four are needed every cycle and do not assume any of them is once-only.

Two other California specifics: fingerprinting is required of all licensees during renewal, and the board runs a diversion program and a loan repayment program that are worth knowing about. Dental hygienists in California are licensed by a separate board, the Dental Hygiene Board of California, so hygienist requirements come from a different source than yours.

X-ray equipment: registration and inspection

The CDPH Radiologic Health Branch registers x-ray facilities and machines and runs the inspection program. RHB operates an online permits and certificates system and a public facility registration lookup, which is a genuinely useful due diligence tool: you can check a practice's registration status before you make an offer.

The most valuable document RHB publishes for dentists is its guidance on preparing for a dental inspection, because it tells you exactly what the inspector will do and what records you must produce. According to that guidance, an inspection includes document review, a physical walkthrough observing staff performing radiologic duties, staff interviews, and physical testing of each machine.

The records RHB expects on site:

• An x-ray machine inventory with manufacturer, model, serial number and location for each unit.
• Staff credentials, including a dentist list and an operator list, plus radiation safety training certificates for unregistered dental hygienists and dental assistants.
• Dosimetry records for the past three years, reviewed, initialed and dated by the registrant designee.
• Preventive maintenance and service records for the x-ray machines from the last year.
• Quality assurance and quality control test records for the past three years.
• A written radiation safety and protection program covering staff competency, training, ALARA principles, patient identification, operator pregnancy policy, radiological emergencies and annual audits.

Note the phrase "radiation safety training certificates for unregistered dental hygienists and dental assistants." That language implies California distinguishes between staff who hold a state credential covering radiography and those who do not, with training certificates required for the latter. We were not able to confirm the exact current requirement for a dental assistant to expose radiographs in California, because the RHB program page would not load for us and the Dental Board's dental assisting page does not address it. Confirm directly with the Dental Board of California and RHB before you assign radiography duties.

We also could not confirm California's registration deadlines, fee amounts, or dental inspection interval. For general mechanics, see dental x-ray registration and inspections.

Buying and selling used equipment in California

Registration and the RHB record

Use the RHB facility registration lookup as a first step in due diligence on any California practice you are considering. It will tell you whether the facility is registered and give you a starting point for questions. Then ask the seller for the four record sets above. A practice that cannot produce dosimetry, service records or a written radiation safety program is a practice with an inspection problem waiting for you.

RHB publishes an "Update Facility Registration" guide, which is the document for adding, moving or removing machines. Do the update when the equipment moves, not at renewal.

Amalgam separators and wastewater

The federal EPA dental rule at 40 CFR Part 441 applies. If you place or remove amalgam and discharge to a publicly owned treatment works, you need a compliant amalgam separator, you follow the best management practices (no flushing scrap amalgam, no bleach or other oxidizing line cleaners), and you file a one-time compliance report with your pretreatment control authority. In California that is typically a sanitation district or a city wastewater program, and many California districts had local dental amalgam programs before the federal rule existed, so expect the local requirements to be at least as detailed as the federal ones.

Call your district at the point of sale and ask what the incoming owner must file. See amalgam separators for equipment selection and recycling records.

Lead, chemicals and decommissioning

California hazardous waste rules are stricter than the federal baseline, and that matters when you clear out a darkroom or retire lead-lined equipment. Spent fixer and developer, lead foil, failed lead aprons and lead-lined panels all need a licensed vendor and a manifest. Do not improvise. See dental waste disposal and disconnecting dental equipment safely, and run the pre-purchase checklist before you buy.

Non-competes and employment

California is the clearest state in the country on this. The Attorney General's consumer alert states that non-compete provisions in employment contracts have generally been void in California for decades, and that non-competes are not enforceable in California.

Two recent laws sharpened the point:

• Senate Bill 699, effective January 1, 2024, makes it unlawful for employers to enter into non-compete agreements with California employees. An employer who attempts to enforce one faces civil liability.
• Assembly Bill 1076 codifies that existing non-compete agreements are void unless they meet a specific statutory exception, and required employers to notify current and certain former employees whose contracts contained an unenforceable non-compete that the agreement is void. That notice was due by February 14, 2024, and failure to comply is an act of unfair competition.

Employees can pursue damages, injunctive relief and reasonable attorney fees if an employer tries to enforce an unlawful non-compete. That fee-shifting provision is what changes employer behavior, because a failed enforcement attempt now costs money rather than just not working.

What survives in California is narrower than a non-compete: confidentiality and trade secret obligations, and covenants tied to the sale of a business or the dissolution of a partnership under separate statutory exceptions. Those are real, and they are why a seller of a California dental practice can still be restricted even though an associate cannot. Get the distinction from a California employment attorney.

At the federal level, the FTC's non-compete rule is not in effect. The Commission voted on September 5, 2025 to dismiss its appeals and accede to the vacatur of the rule. California's own law is doing all the work here. See non-compete agreements for dentists.

What we could not confirm

• The specific certificate or course a California dental assistant must hold to expose radiographs. The RHB program page would not load for us and the Dental Board's dental assisting page does not address it. Confirm with the Dental Board and RHB.
• How often each of the four mandatory dentist CE courses must be repeated. The board does not state the interval on its CE page.
• California x-ray registration fees, registration deadlines after acquiring a machine, and the dental inspection interval.
• The exact ownership rules for a California dental corporation, including what share of a corporation non-dentist licensed professionals may hold. The Dental Board page we tried returned an error. Confirm with the board and a California dental attorney.
• California dental hygienist CE requirements. Those come from the Dental Hygiene Board of California, a separate agency.
• Sales and use tax treatment of dental equipment, including private-party purchases. Confirm with CDTFA and your CPA.

Where to verify

• Dental Board of California: dentist continuing education, renewal, and dental assisting licensees
• Dental Hygiene Board of California: dhbc.ca.gov
• CDPH Radiologic Health Branch: program page, preparing for a dental inspection, permits and certificates online, and the facility registration lookup
• California Attorney General: consumer alert on worker rights and non-competes
• US Environmental Protection Agency: dental effluent guidelines, 40 CFR Part 441
• Federal Trade Commission: September 2025 statement on the non-compete rule
• California Department of Tax and Fee Administration: cdtfa.ca.gov

Putting it to work

California rewards documentation more than any other state on this list. Build the written radiation safety and protection program, keep three years of dosimetry and QA records, and keep a machine inventory with serial numbers so an inspector's first question has an immediate answer. On the employment side, the work is subtraction: strip non-competes out of every template, and rely on confidentiality, trade secret and sale-of-business provisions that California law actually supports.
