New Mexico is one of a small number of states that put dentists inside a statutory non-compete restriction rather than leaving them to general contract law. It is also one of the few states that charges nothing at all to register an x-ray machine. Both of those facts are unusual enough to change how you plan a startup or a transition here, and both are easy to get wrong if you carry assumptions in from a neighboring state.
Key takeaways
- Dental licenses in New Mexico renew on a three year cycle running July 1 through June 30. Dentists need 60 CE hours per triennial cycle, with a maximum of 30 online, webinar or self-study. Hygienists need 45, with the same 30 hour self-study cap.
- Mandatory content inside those totals: current BLS or CPR certification (which cannot be self-study), and an infection control and sterilization course each renewal period. Dentists with a DEA registration add 3 hours on controlled substances.
- The Radiation Control Bureau currently charges no registration fee for x-ray machines. Registration is a form emailed to the bureau, typically processed in under two weeks.
- When a machine is removed, transferred or replaced, you must notify the bureau within 15 days with the destination, manufacturer, model, serial number, and the disposal or transfer date. Buying an existing practice uses a Change of Control and Change of Ownership form.
- New Mexico's health care practitioner agreements law names dentists among the covered professions. That puts dentist non-competes inside a statutory framework rather than leaving them entirely to case law.
Rules change. Everything below was checked against an official New Mexico or federal source in September 2026. The non-compete article has been recompiled and amended more than once, fees can be introduced, and CE rules change. Confirm with the agency and with counsel before acting.

License renewal and continuing education
New Mexico runs a three year renewal cycle, July 1 through June 30, which is long enough that people forget where they are in it. The board is explicit that all CE must be obtained during the renewal period and completed before you renew. There is no borrowing from the next cycle.
Under 16.5.10 NMAC, dentists need 60 hours of continuing education per triennial cycle, of which a maximum of 30 hours may be online, webinar or self-study. For a licensee whose initial period is shorter than three years, the requirement is prorated at 20 hours per year. Mandatory content sits inside the 60: current basic life support or CPR certification from the American Heart Association, the American Red Cross or ASHI, which the rule says may not be obtained by self-study; a course in infection control techniques and sterilization procedures each renewal period; and, for a dentist holding a DEA registration to prescribe controlled substances, three hours covering pharmacology, abuse and addiction awareness, applicable regulations and pain management. Dentists holding sedation or general anesthesia permits carry additional requirements tied to the permit.
Under 16.5.23 NMAC, dental hygienists need 45 hours per triennial cycle with the same 30 hour cap on self-study, current BLS or CPR that is not self-study, and an infection control course each period.
The board calls out a specific trap: taking more than 8 CEU hours in a single day. Marathon weekend courses can produce certificates the board will not accept in full. It also flags non-approved providers and missing verification of attendance as the two other common reasons hours get rejected on audit. Keep certificates, not portal screenshots.
X-ray equipment: registration and inspection
The New Mexico Environment Department's Radiation Control Bureau runs the radiation machine program under 20.3 NMAC, covering more than 2,000 radiation machine facilities statewide. The mechanics are refreshingly simple compared with most states:
- Fee. The bureau states that there are currently no registration fees for the registration of x-ray machines in New Mexico. That is unusual and worth confirming before you budget, because it is exactly the kind of thing a legislature changes.
- How to register. Download the X-Ray and Radiation Machine Registration Form and submit it to the bureau by email. The bureau says it aims to complete processing in under two weeks.
- Equipment changes. When you remove, transfer or replace a machine, notify the bureau within 15 days and include the machine's destination, the manufacturer, model and serial number, and the disposal or transfer date.
- Ownership changes. Buying an existing practice uses a Change of Control and Change of Ownership form submitted to the same address.
- Out of state operators. Registrants from other states must notify the bureau at least three days before operating equipment in New Mexico.
The bureau says facilities undergo regular inspections to confirm exposure levels stay within legal limits and as low as reasonably achievable, but it does not publish an inspection interval for dental facilities on the pages we could read. Ask when you register. The main bureau number is 505-476-8600.
For general mechanics, see our guide to dental x-ray registration and inspections, plus the equipment pages on intraoral x-ray units, panoramic units and CBCT units.
Buying and selling used equipment in New Mexico
The 15 day clock is the one to remember
New Mexico gives you a specific, short window. If you sell a pan to a colleague, scrap a tube head during a remodel, or swap an intraoral unit for a newer one, the bureau expects notice within 15 days with the destination and the machine's identifying details. That is a calendar item, not a someday item. Sellers who skip it stay on the hook for a machine that is no longer in the building; buyers who skip it operate equipment that is not on their registration.
Practice purchases use a different form
Buying an existing practice is not the same filing as buying a machine. The bureau publishes a Change of Control and Change of Ownership form for exactly that situation. Put it on the closing checklist alongside the lease assignment and the Medicaid and payer credentialing paperwork, and ask the seller for a copy of the current registration with its machine list so you can walk the building and reconcile it.
Amalgam separators and wastewater
There is no separate New Mexico separator rule for you to chase. The federal EPA dental effluent rule at 40 CFR Part 441 applies to dental dischargers that place or remove amalgam and send wastewater to a publicly owned treatment works: a compliant separator, the best management practices (no flushing scrap amalgam, no bleach or other oxidizing line cleaners), and a one-time compliance report filed with your pretreatment control authority, usually the municipal utility. EPA does not address ownership changes, so ask the utility what it wants from an incoming owner. See amalgam separators for sizing and recycling records.
Lead, chemicals and old processors
Lead foil, lead aprons, spent fixer and developer, and lead-lined cabinets all need a licensed waste vendor and a manifest you keep. See dental waste disposal and disconnecting dental equipment safely. Before you buy any used imaging, run the pre-purchase equipment checklist and read the hidden costs of buying used equipment.
Non-competes and employment
New Mexico regulates health care practitioner agreements by statute, and dentists are inside the covered group. The 2025 legislation that added veterinarians to the definition, House Bill 366, lists the covered professions in its amended text: dentists, physicians, osteopathic physicians, podiatric physicians, certified registered nurse anesthetists, certified nurse practitioners, certified nurse-midwives, psychologists, physician assistants, pharmacists, and now veterinarians. That is the list a New Mexico associate should be reading.
The structure of the law, as we read it, is that a non-compete provision restricting a covered practitioner from providing clinical health care services becomes unenforceable upon termination of the agreement, its renewal, or the practitioner's employment. The law also voids provisions that subject the agreement to another state's law or that require litigation outside New Mexico, which is the clause DSO and multi-state employer templates most often carry. A significant carve-out exists for agreements between practitioners who are shareholders, owners, partners or directors of a health care practice, so a buy-in or partnership covenant is a different analysis from an employed associate's covenant.
Two honest cautions. First, we confirmed that dentists are within the covered definition from the Legislature's own bill text, but we read the operative restriction from a statutory compilation rather than the state's own statute portal, which we could not open. Second, this article has been recompiled and amended repeatedly, and different professions were brought in on different dates, so whether a specific agreement is covered can turn on when it was signed, renewed or extended. Have a New Mexico attorney read the current statute against your actual contract.
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 court decisions vacating the rule, so state law governs. See our national overview of non-compete agreements for dentists and the associate contract red flags guide.
What we could not confirm
- The operative text of the health care practitioner non-compete statute from New Mexico's own statute portal. We verified the covered professions from the Legislature's bill text and read the restriction from a compilation. Read the current statute directly or have counsel do it.
- Which applicability date governs dentists specifically, and whether an agreement signed before that date is covered.
- How often the Radiation Control Bureau inspects dental facilities. The bureau confirms it inspects but does not publish an interval.
- Whether New Mexico requires a separate radiography credential for dental assistants before they expose radiographs. The board's CE page does not address it and we could not confirm it from the board's own rules.
- Dental assistant CE hours. The board points to 16.5.36 NMAC, which we did not open.
- Gross receipts and compensating tax treatment of dental equipment purchases, including private-party sales. Confirm with Taxation and Revenue and your CPA.
- New Mexico limits on non-dentist ownership of a dental practice. Confirm with a dental-specific attorney.

Putting it to work
If you are signing a New Mexico associate contract, the first thing to check is the choice of law and venue clause, because the statute reaches that directly, and the second is whether the restrictive covenant is written as an employment covenant or as an owner covenant, because the carve-out for shareholders, owners, partners and directors changes the analysis. If you are buying a practice, file the Change of Control form and reconcile the seller's machine list against the building. If you are selling equipment, the 15 day notice is the single cheapest piece of compliance in the state.
