How Long Does It Take to Become a Dental Assistant?
How fast you can become a dental assistant depends on which role you are aiming for. You can be job-ready as an entry-level dental assistant in a matter of weeks, while becoming a licensed Registered Dental Assistant (RDA) takes longer because California requires qualifying work experience and an exam.

Entry-level dental assistant: a few weeks
The fastest route into the field is an accelerated training program. Roseville Dental Academy's Dental Assisting Program runs 9 weeks and totals 210 hours, combining online lectures, hands-on chairside practice, and a 64-hour internship.
After completing an accelerated program and the required Infection Control and Dental Practice Act courses, you can begin applying for unlicensed dental assistant roles right away.
Registered Dental Assistant (RDA): 15+ months
The RDA license is a longer commitment. California outlines work-experience and blended-education pathways that can involve at least 15 months and roughly 1,280 hours of qualifying chairside experience, depending on the pathway you choose.
During that time you complete the required course certificates, submit an application to the Dental Board of California, and pass the RDA Combined Written and Law and Ethics Examination.
What can speed up or slow down your timeline
Your personal timeline depends on a few factors within your control.
- How quickly you complete initial training and the required certificates.
- How soon you get hired and start logging qualifying work hours.
- Whether you complete RDA-track courses (Coronal Polish, Sealants, Radiation Safety) along the way.
- Application processing and exam scheduling with the Dental Board.
