The Path to National Certification
Becoming a nationally certified dental assistant demonstrates a commitment to your profession that goes beyond the basic requirements.
Step 1: Graduate from an Accredited Program To be eligible for the top national certifications, you must first graduate from a dental assisting program that is accredited by the Commission on Dental Accreditation (CODA). These certificate or diploma programs are typically offered at community colleges and vocational schools and take about 9 to 11 months to complete. They include both classroom instruction and hands-on clinical experience.
Step 2: Meet the Experience or Education Requirements National certifying bodies have specific eligibility pathways. For example, to sit for the most recognized certification, you will need to meet one of their required pathways, which usually includes graduating from a CODA-accredited program.
Step 3: Pass a National Certification Exam The final step is to pass a comprehensive exam from a recognized national certifying board. The premier certification organization is the Dental Assisting National Board (DANB).
The Gold Standard: DANB Certification
Earning a DANB certification is the most respected achievement in the dental assisting profession. The main credential is the Certified Dental Assistant™ (CDA®). To earn this, you must pass three separate exams:
- Radiation Health and Safety (RHS®)
- Infection Control (ICE®)
- General Chairside Assisting (GC)
Expert Tip: Understand Your State’s Specific Requirements Dental assisting is regulated at the state level, and the laws vary significantly. Some states require no formal education, while others mandate that you graduate from an accredited program and pass specific exams (like the RHS® exam for taking X-rays). Before you enroll in any program, visit your state’s Board of Dentistry website to understand the exact requirements for the tasks you want to perform.
FAQ: Your Questions About Dental Assisting Certification

It depends on your state. Some states require assistants to be licensed or registered to perform certain tasks (especially expanded functions like placing fillings or taking X-rays).

Can I get my dental assisting certification online?
You can complete the academic portion of your training online, but you cannot become a certified dental assistant without extensive in-person, hands-on clinical training. All accredited programs, including those with online coursework, use a hybrid model that includes a mandatory clinical internship or externship where you will practice skills in a real dental office setting.

Expanded Function Dental Assistants (EFDAs) are experienced assistants who have completed additional training and certification to perform certain reversible, intraoral procedures under the direct supervision of a dentist.
