Which is better, RDA or CDA?
Which is better, RDA or CDA?
Good question — RDA (Registered Dental Assistant) and CDA (Certified Dental Assistant) are both respected credentials, but they differ in scope, recognition, and career impact. Which one is “better” depends on your goals and location. Here’s a breakdown:
What is a CDA?
Certified Dental Assistant credential is awarded by the Dental Assisting National Board (DANB).
It’s recognized across the U.S. and often required for higher-level dental assisting roles.
To earn it, you must pass the DANB exam, which covers radiation health and safety, infection control, and general chairside assisting.
CDAs usually have more mobility between states, since the certification is nationally recognized.
What is an RDA?
Registered Dental Assistant is a state-level license (for example, California, Texas, and a few other states).
Requirements vary by state, but often include passing exams, background checks, and completing an accredited dental assisting program.
RDAs may have additional duties allowed by their state’s dental board (like coronal polishing, sealant placement, or expanded functions).
It’s powerful locally, but doesn’t always transfer if you move to another state.
Which Is Better?
If you want national recognition and career flexibility, CDA is usually the better choice. It signals competence across the country.
If you’re in a state that requires or highly values RDA licensure, like California, then RDA may open more opportunities locally.
Many assistants actually hold both: CDA for national credibility and RDA for expanded state practice privileges.
Bottom Line
Neither is “better” in every situation.
CDA = broader recognition, mobility, strong baseline credential.
RDA = more hands-on duties, but state-specific.
If your goal is to maximize career growth, the best path is often earning CDA first for national standing, then obtaining RDA if your state offers expanded functions.
Also, if you're searching for more than just a job, moreover, a career with stability, respect, and long-term potential; then becoming a licensed dental assistant could be your perfect path forward.
