Registered Dental Assistant job description

Registered dental assistant is a state title, and what it takes to earn one changes at each state line. California, Texas, and Michigan all use it, with different requirements behind each. BLS does not separate registered assistants from other dental assistants. Everyone on the job shares one wage line, which put the national median at $48,070 in May 2025, and state medians on that line ran from $37,760 in Utah to $65,270 in Minnesota.

Core Duties and Responsibilities

States may require registration or licensing, the Handbook says, before an assistant works in radiography, infection control, or other specialties. Beyond those regulated tasks, the day follows the dental assistant's list in O*NET: preparing patients and trays, sterilizing instruments, assisting chairside, recording treatment, taking histories and vital signs, and passing on the dentist's postoperative instructions. Where state law allows, registered assistants also apply fluoride, take preliminary impressions, and fabricate temporary restorations.

Common Skills and Technologies

The registration courses teach the regulated skills directly: x-ray positioning and exposure, infection control, and the state's dental law. The rest is the dental assistant's skill profile, led by active listening and speaking, with Henry Schein Dentrix as the practice software named in postings.

Education, Training, and Career Path

In California, the license requires a board-approved program or 15 months of work experience, courses in radiation safety and coronal polishing, basic life support, and the state's written and law exam. Since July 1, 2025, California has also accepted the Certified Dental Assistant credential and a preceptorship route. Texas registration takes a course from its board of dental examiners covering x-rays, jurisprudence, and infection control, or the national Certified Dental Assistant credential plus the Texas jurisprudence assessment. Michigan asks for a program accredited by the Commission on Dental Accreditation and a board-approved written and clinical exam. New York goes further and licenses dental assistants outright, and Minnesota's version is the licensed dental assistant. Its O*NET preparation level is Job Zone Three.
