How to become a Certified Dental Assistant

There are many ways to become a certified dental assistant. One way is to attend a dental assisting program at a community college or vocational school. Many of these programs take between one and two years to complete, and they often include both classroom and clinical instruction.

Another way to become a certified dental assistant is to complete an apprenticeship program. Apprenticeship programs can last up to four years, and they combine on-the-job training with classroom instruction.

Once you have completed a dental assisting program or an apprenticeship, you will need to pass a certification exam in order to become a certified dental assistant. The most common certification exams for dental assistants are the Dental Assisting National Board (DANB) exams. To qualify to take the DANB exams, you must have completed an accredited dental assisting program or apprenticeship.

Once you have passed the DANB exams, you will be a certified dental assistant (CDA). CDAs are required to renew their certification every few years by completing continuing education courses and passing a recertification exam.
