Nebraska administers dental licensure through the Department of Health and Human Services rather than through a freestanding board office, which means the regulations you need are numbered NAC titles rather than board policies. The same department runs radiation control. That single-agency structure makes Nebraska easier to research than most states, as long as you know which title to open.
Key takeaways
- Dentist licenses renew on March 1 of odd-numbered years. A license may be placed on inactive status at any time.
- Dentists must complete 30 hours of acceptable continuing education during the preceding 24-month period. Nebraska audits after renewal and may request documentation, so keep records for at least four years.
- Holders of general anesthesia, deep sedation or moderate sedation permits must complete at least six hours of CE directly related to administering and managing anesthesia or sedation in the dental office.
- X-ray facilities register with DHHS within 30 days following the start of facility operation, service providers register 30 days before providing services, and any change to registration information must be reported within 30 days. Renewal is annual, with notices sent roughly eight weeks before expiration.
Rules change, so verify before you act. Everything below was checked against an official Nebraska or federal source in September 2026. Fee amounts and regulations change. Confirm with DHHS Licensure and with Radiation Control before you rely on any of it, and take employment, ownership and tax questions to a Nebraska attorney or CPA.

License renewal and continuing education
The renewal date is fixed and easy to remember: March 1 of odd-numbered years. That means every Nebraska dentist renews at the same time, which also means the department's phone lines are busiest in February. Do not leave it to the last week.
The CE requirement is 30 hours of acceptable continuing education during the preceding 24-month period prior to license expiration. Two structural points matter more than the number:
- The audit happens after renewal. Nebraska performs post-renewal audits and may request documentation. You attest at renewal and prove later, which is why people get caught.
- Keep records four years. The department asks licensees to retain documentation for at least four years, longer than a single renewal cycle.
Sedation permit holders carry an additional requirement. Everyone holding a general anesthesia, deep sedation or moderate sedation permit must attend at least six hours of continuing education directly related to the administration and management of anesthesia or sedation for the dental office.
What counts as acceptable CE is defined in 172 NAC 56, the practice of dentistry regulation. If you are buying courses outside the mainstream dental conference circuit, check the regulation rather than trusting a provider's claim of approval.
Because everyone renews on the same date, a practice with multiple dentists can run one internal CE audit each January: pull certificates for the previous 24 months into a shared folder, confirm the sedation hours for anyone with a permit, and be done. A four-year retention window means that folder should not be deleted after renewal.
X-ray equipment: registration and inspection
DHHS Radiation Control registers both facilities and service providers, and the timing rules are specific:
- Facilities register within 30 days following the start of facility operation.
- Service providers, meaning companies that install, service, sell or take radiation measurements, register 30 days before providing any services.
- Changes to registration information must be reported within 30 days of the change.
Renewal is annual, and the department sends renewal notices roughly eight weeks before the expiration date. The detailed requirements sit in 180 NAC 18.
On fees, the department publishes a sample annual renewal document to show facilities what the form looks like. In that example the fee is charged per machine rather than per facility, and the sample shows $70 for a single medical diagnostic general x-ray machine. Treat that as an illustration of the structure, not as the current price: the sample is not a fee schedule and the amount may have changed. Ask Radiation Control what your machines will cost before you budget.
The pages we read do not publish an inspection interval for dental facilities. For general mechanics see dental x-ray registration and inspections, plus intraoral x-ray units and panoramic units.
Buying and selling used equipment in Nebraska
Check that your installer is registered
Nebraska's requirement that service providers register 30 days before providing services is a useful filter when you are hiring someone to install a used unit. Ask the company whether it is registered with Nebraska Radiation Control. An installer who cannot answer that question quickly is telling you something about how they work.
Every change is a 30-day filing
Adding a used pan, removing a dead intraoral unit, moving to a new suite in the same building, or changing the name on the practice entity are all changes to registration information, and the department gives you 30 days. In a practice sale, both sides have filings to make, and neither one closes the other's obligation.
Ask the seller for the current facility registration and machine list, compare it to what is installed, and note the annual expiration date so you know whether a renewal lands shortly after closing. Our pre-purchase equipment checklist and hidden costs of buying used equipment cover the wider diligence, and closing a dental practice covers the exit.
Amalgam separators and wastewater
The federal EPA rule at 40 CFR Part 441 applies to dental offices that place or remove amalgam and discharge to a publicly owned treatment works. You operate and maintain an amalgam separator, you do not discharge scrap amalgam or use certain line cleaners, and you file a one-time compliance report with your pretreatment control authority, usually the municipal utility. Practices in small Nebraska towns that are not connected to a treatment works should confirm what applies to them rather than assuming the rule does or does not reach them. See amalgam separators and dental waste disposal.
Non-competes and employment
We could not point you at a Nebraska statute that sets numeric limits on non-compete agreements for dentists. Nebraska does not appear to have written duration, mileage or salary thresholds into law for health care employment, and we could not confirm the current judicial standard from an official state source. Enforceability is therefore a case law question applied to your specific contract, which is a Nebraska employment attorney's job rather than a web page's.
The federal picture is settled for now. The FTC's non-compete rule is not in effect: on September 5, 2025 the Commission voted to dismiss its appeals and accede to the vacatur of the rule after a district court held the agency lacked authority to issue it. State law governs.
What you can do without a lawyer is negotiate the terms that determine how much a covenant actually costs you. Duration, radius and where the radius is measured from, whether it covers all of the employer's locations or only the one you worked at, whether it survives a termination without cause, and whether patient and staff solicitation are treated separately from practicing at all. Our national overview of non-compete agreements for dentists explains each, and the associate contract review checklist gives you a markup list. Also read associate contract red flags and, if you are weighing offers, how to negotiate an associate offer.
What we could not confirm
- Dental hygienist CE hours and renewal dates in Nebraska. The dentist page states the dentist requirements; hygienist requirements sit in 172 NAC 57.
- Current Nebraska x-ray registration fee amounts. The sample renewal document we read shows a per-machine structure with a $70 example, but it is an illustration rather than a fee schedule.
- Inspection intervals for dental x-ray facilities in Nebraska.
- What training or credential a dental assistant must hold before exposing radiographs. Dental assistants are addressed in 172 NAC 53, which we did not open.
- Whether any Nebraska statute limits non-competes, and how Nebraska courts treat dental covenants.
- Nebraska limits on non-dentist ownership of a dental practice.
- Sales and use tax treatment of dental equipment, including private-party purchases. Confirm with the Nebraska Department of Revenue and your CPA.
Where to verify
- Nebraska DHHS Licensure: dentist licensure and renewal and the statutes relating to the Dentistry Practice Act
- Nebraska administrative rules: Title 172, professional and occupational licensure
- Nebraska DHHS Radiation Control: x-ray registrations and the Radiation Control Act statutes
- Nebraska One Stop: registration of services for radiation generating equipment
- US Environmental Protection Agency: dental effluent guidelines, 40 CFR Part 441
- Federal Trade Commission: September 2025 statement acceding to vacatur of the non-compete rule
Putting it to work
Nebraska rewards two calendar entries and one folder. The calendar entries are March 1 of odd-numbered years for your license and the annual expiration date on your x-ray facility registration. The folder is a CE archive you keep for four years, because Nebraska audits after renewal rather than before it, and the documentation request arrives when you have already stopped thinking about it.
On the equipment side, remember that 30 days applies to almost everything: starting operation, adding or removing a machine, changing your address or entity name. Make it a standing rule that whoever handles a change also files it that month.
