The single most important operational fact about practicing in Mississippi is that a dental assistant may not expose radiographs without a current Mississippi radiology permit, and the board does not issue those permits based on another state's credential. If you hire an experienced assistant from Alabama or Tennessee, they cannot take a bitewing on day one. Everything else on this page matters, but that one will change your schedule.
Key takeaways
- Dentists complete a minimum of 40 hours of CE per two-year cycle and hygienists 20. The reporting period runs on a calendar year basis, from January 1 through December 31.
- Keep certificates of completion or sponsor verification for at least three years. Board Regulation 41 lists the approved sponsors.
- A dental assistant must hold a currently valid Mississippi radiology permit before exposing radiographs. Qualifying paths are current DANB certification, graduation from an ADA or CODA accredited dental assisting, dental hygiene or dental program, or a board-approved radiology seminar completed within 90 days of application.
- The board does not issue radiology permits by reciprocity or based on another state's licensure. There is no shortcut for an experienced out-of-state hire.
Rules change, so verify before you act. Everything below was checked against an official Mississippi or federal source in September 2026. Board regulations and fee schedules change. Confirm with the Mississippi State Board of Dental Examiners and the MSDH Division of Radiological Health, and take employment and tax questions to a Mississippi attorney or CPA.

License renewal and continuing education
The board's CE FAQ states the totals plainly: a minimum of 40 hours per two-year cycle for dentists and 20 hours per two-year cycle for dental hygienists. The reporting period runs on a calendar year basis, from January 1 through December 31, an approach the board put in place effective January 1, 2014.
Format is generous. The board grants credit for computer-based courses, video courses, audio courses, reading, and correspondence or home study courses, provided they come through sponsors approved in Board Regulation 41. If you are choosing a provider, the approved sponsor list in Regulation 41 is the document to check before you pay, not after.
On records, licensees must keep certificates of completion or verification correspondence from the sponsor for a minimum of three years. That is longer than one renewal cycle, which is deliberate: it lets the board audit across cycles. Keep the PDFs, not just the portal history.
The FAQ we read does not name mandatory topics such as CPR, infection control or opioid prescribing. That does not prove none exist, only that the FAQ does not list them. Read Regulation 41 directly or call the board before you assume there is no required content.
Radiology permits for dental assistants
This is the section to read twice if you hire.
Mississippi does not license dental assistants for general assisting duties, but it does require a currently valid Mississippi radiology permit before an assistant exposes radiographs in a dental office. Students actively enrolled in an ADA-accredited program are exempt while enrolled.
An applicant qualifies through one or more of three paths:
- Current certification from the Dental Assisting National Board
- Completion of an ADA or CODA accredited dental assisting, dental hygiene or dental program
- Successful completion of a board-approved radiology seminar within 90 days of application
The board states that it only recognizes DANB certification and ADA or CODA accreditation, and that it does not issue permits based on reciprocity or on licensure in another state. Applicants who graduated more than twelve months before applying must also provide sworn statements from all employers over the past five years confirming employment and radiograph duties.
Two administrative traps follow. A new permit must be renewed immediately upon receipt, which functions as an activation step and is not intuitive. And failure to renew within 60 days triggers a $20 penalty per 30-day period, with permits voided for non-renewal unable to be reinstated. Applications and renewals have been filed through the board's online portal since February 1, 2022.
Build the permit into your hiring timeline, not your onboarding checklist. If your new assistant needs a board-approved radiology seminar, you need to know that during the interview, because until the permit issues you have an assistant who cannot cover the radiographs your schedule assumes.
X-ray equipment: registration and inspection
Machine registration is separate from the permit and sits with the MSDH Division of Radiological Health. The division states that it oversees the registration, inspection and certification of approximately 7,500 x-ray machines across Mississippi.
The forms it publishes tell you what events the state expects to hear about:
- Form 803, application for registration of healing arts or veterinary x-ray units
- Form 773, application for radiation services
- Form 1360, transfer receipt record
- FDA Form 2579, report of assembly of a diagnostic x-ray system, submitted to xrayregistration@msdh.ms.gov or mailed to the division in Pearl
The existence of a transfer receipt record form is the detail that matters for used equipment. Mississippi has a dedicated piece of paper for moving a machine from one party to another, which means transfers are expected to be documented rather than assumed.
The division's pages do not publish registration fees, renewal frequency or inspection intervals, so treat all three as questions for the X-ray Branch. For general mechanics see dental x-ray registration and inspections, plus intraoral x-ray units and panoramic units.
Buying and selling used equipment in Mississippi
Use the transfer receipt record
When a used x-ray unit changes hands in Mississippi, ask about Form 1360. Whether you are the buyer or the seller, a documented transfer protects both sides: the seller establishes that the machine left their control, and the buyer establishes when it arrived. Combine that with FDA Form 2579 when a system is assembled at your location, which is the installer's report and something you should get a copy of rather than trusting it was filed.
Diligence in a practice purchase
Ask the seller for the current registration for each machine and compare it to the operatories. Ask whether any unit has been sold, scrapped or moved without paperwork. And on the staffing side, ask which assistants hold current radiology permits and when each expires, since a permit that lapsed and was voided cannot be reinstated. That is a hiring liability you can inherit without noticing.
Run the pre-purchase equipment checklist and read the hidden costs of buying used equipment before you commit, and see closing a dental practice if you are on the exit side.
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 local sewer utility. Ask what that authority expects from an incoming owner. See amalgam separators and dental waste disposal for lead, chemicals and sharps.
Non-competes and employment
We could not point you at a Mississippi statute setting numeric limits on non-compete agreements for dentists or other health care workers. Unlike Maine, Maryland or Texas, Mississippi does not appear to have written duration, mileage or salary thresholds into law for this context, and we could not confirm the current judicial standard from an official state source. That means your agreement is judged on its own terms and on Mississippi case law, and the only reliable answer comes from a Mississippi employment attorney reading your document.
The federal layer 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.
Practically, that puts more weight on negotiation than on statute. Duration, radius measured from where you actually work rather than from every office the employer owns, what happens if you are terminated without cause, and whether the restriction covers solicitation of patients and staff separately from practicing at all, are the four terms that decide how much a covenant costs you. Our national overview of non-compete agreements for dentists walks through each, and the associate contract review checklist plus associate contract red flags give you a markup list.
What we could not confirm
- Mandatory CE topics in Mississippi, such as CPR, infection control or opioid prescribing. The board's CE FAQ does not list any. Read Board Regulation 41 or ask the board.
- The Mississippi dentist and hygienist renewal deadline and fee amounts.
- The radiology permit application fee and renewal period length. The board describes the penalty structure but the FAQ we read does not state the fee or the term.
- MSDH x-ray machine registration fees, renewal frequency and inspection intervals. The division's pages do not publish them.
- Whether Mississippi imposes CE on radiology permit holders.
- Whether any Mississippi statute limits non-competes, and how Mississippi courts treat dental covenants.
- Mississippi limits on non-dentist ownership of a dental practice, and sales and use tax treatment of dental equipment. Confirm with counsel and your CPA.
Where to verify
- Mississippi State Board of Dental Examiners: board home, CE FAQ, radiology permits FAQ, and radiology applications and renewals
- Mississippi State Department of Health: X-ray Branch and radiological health forms and applications
- 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
- Occupational Safety and Health Administration: osha.gov
Putting it to work
Make the radiology permit a standing item in your hiring process. Ask every assistant candidate whether they hold a current Mississippi permit, and if not, which qualifying path they will use and how long it takes. Renew permits the moment they arrive, because that first renewal is an activation step and the 60-day penalty clock is unforgiving. On equipment, use Form 1360 on every transfer and keep a copy of the assembly report for anything installed at your address.
