How to Become a Dental Assistant in Minnesota
By Elizabeth Carr, DHA · 5 min read
An unlicensed dental assistant in Minnesota needs no registration at all. Registration enters only as the limited radiology registration, which is one of the two routes to exposing x-rays. The other route is full licensure as a Licensed Dental Assistant, which is what unlocks expanded functions. Verify current rules with the Minnesota Board of Dentistry before enrolling in any course.
An unlicensed dental assistant in Minnesota needs no registration at all. Registration enters only as the limited radiology registration for exposing x-rays, and licensure as a Licensed Dental Assistant is what unlocks expanded functions. This guide comes from DentalReady's fifty-state requirements research: what you can do from day one in Minnesota, the certifications that expand your duties, and the realistic path in. Rules change, so the Minnesota Board of Dentistry link at the bottom is always the final word.
What you can do from day one
Minnesota practices hire entry-level assistants and grow their duties with training. The table below lists duties the state allows dental assistants to perform, with training or certification requirements noted where they apply.
| Allowed duty |
|---|
| Chairside assisting |
| Taking radiographs (limited radiology registration or licensed dental assistant) |
| Coronal polishing (licensed DA) |
| Applying fluoride varnish (sealants require a licensed dental assistant) |
| Taking digital impressions (other impressions require a licensed dental assistant) |
| Placing temporary restorations (licensed DA) |
Certifications and X-rays in Minnesota
No registration is required for basic duties. An unlicensed assistant must keep current CPR certification and comply with current infection control practice, both of which are the dentist's responsibility to ensure. The Licensed Dental Assistant credential is what unlocks expanded duties.
To expose x-rays you must either hold a limited radiology registration or be a Licensed Dental Assistant. The limited radiology registration requires a board-approved dental radiology course, a pass on the DANB Radiation Health and Safety exam or another board-approved national radiation exam within the last five years, a pass on the Minnesota jurisprudence exam within the last five years, and current CPR certification.
The fastest realistic path
Step 1: Build real preparation first: instruments, procedure flow, infection control, and patient communication, so a hiring dentist sees you as useful in week one.
Step 2: Apply to entry-level and willing-to-train postings across Minnesota, and ask each practice which certifications they sponsor.
Step 3: Complete the certifications above as your duties grow, starting with radiography, and confirm every requirement with the Minnesota Board of Dentistry.
Common questions

An unlicensed dental assistant needs no registration at all. Registration enters only as the limited radiology registration for exposing x-rays. Full licensure as a Licensed Dental Assistant requires a CODA-accredited programme, the DANB Certified Dental Assistant exam, and the Minnesota jurisprudence exam.
Can dental assistants take X-rays in Minnesota?
You need either a limited radiology registration or an LDA licence. The registration requires a board-approved dental radiology course, a pass on the DANB Radiation Health and Safety exam or another board-approved national radiation exam within five years, and a pass on the Minnesota jurisprudence exam within five years. Many assistants complete this after being hired, often with employer support.
