RDA vs CDA: Which Dental Assistant Certification Should You Choose?
RDA vs CDA: Which Dental Assistant Certification Should You Choose?
If you are starting a career in dental assisting, you may be wondering: what’s the difference between RDA and CDA, and which one is better for me? Both credentials are respected, but they serve different purposes. Understanding the differences can help you make the right choice for your career.
What Is a CDA?
A Certified Dental Assistant (CDA) is a nationally recognized credential awarded by the Dental Assisting National Board (DANB).
Exam Requirements: Candidates must pass the DANB exam, which covers chairside assisting, radiation health and safety, and infection control.
Recognition: The CDA credential is accepted across the United States, making it ideal if you plan to move or want national recognition.
Career Benefits: Holding a CDA demonstrates professional knowledge, improves employability, and can increase pay.
What Is an RDA?
A Registered Dental Assistant (RDA) is a state-level license. Requirements vary depending on where you live.
State Specific: States like California and Texas require dental assistants to register and may provide expanded duties.
Extra Responsibilities: RDAs can often perform additional clinical tasks such as coronal polishing, placing sealants, or assisting with more advanced procedures.
Mobility: Since RDA requirements differ, moving to another state may require retaking exams or additional training.
RDA vs CDA: Key Differences
CDA = National recognition, mobility, baseline professional standard.
RDA = State recognition, often expanded clinical duties, but limited portability.
Many dental assistants pursue both certifications: CDA for national credibility and RDA to gain local authority for expanded functions.
Which Is Better for Your Career?
Choose CDA if… you want flexibility to work anywhere in the U.S. and a nationally respected credential.
Choose RDA if… you live in a state that requires registration or allows RDAs to perform more duties that CDAs cannot.
Best Path: Earn CDA first, then add RDA if your state offers it. This gives you maximum mobility and the broadest career opportunities.
Conclusion
Both CDA and RDA are valuable, but the right choice depends on your goals. If you want national recognition, start with CDA. If your state requires RDA or you want to take on more hands-on duties, add that credential too. Many of the top dental assistants hold both, giving them career flexibility and the chance to expand their skills in the dental field.
