New Hampshire does not license or register dental assistants. Rule Den 302.06 qualifies you area by area instead, through an approved course and a clinical hour threshold for each duty. This guide comes from DentalReady's fifty-state requirements research: what you can do from day one in New Hampshire, the certifications that expand your duties, and the realistic path in. Rules change, so the New Hampshire Board of Dental Examiners link at the bottom is always the final word.
What you can do from day one
New Hampshire 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.

Certifications and X-rays in New Hampshire
No registration with the NH Board of Dental Examiners is required to work as a dental assistant. Qualification happens area by area under rule Den 302.06. Dental radiology requires 200 clinical hours of experience, a course of at least eight lecture hours and eight laboratory hours, and a passing score on the radiology written examination of the Dental Assisting National Board. You keep the course records and provide them to the board on request.
CPR certification is required for specific expanded duties under Den 302.06, including nitrous oxide monitoring, rather than for dental assisting generally.
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 New Hampshire, 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 New Hampshire Board of Dental Examiners.
Common questions
