Qualifying for Dental Assisting Jobs through Education, Certification, and Training

A typical dental assistant job description includes tasks that candidates can best develop competency to perform through education and certification:

Dental Assisting Program Completion

One of the most common job requirements is undoubtedly a certificate, diploma or associate’s degree from a Commission on Dental Assisting (CODA)-accredited program in dental assisting. These CODA-accredited programs include a clinical externship and all of the necessary coursework to prepare dental assistant job candidates to meet the requirements that most employers set.

National Certification

Thirty-eight states defer to Dental Assistant National Board (DANB) certification as the standard for qualifying dental assistants for state registration and licensure purposes. It has also become the standard among dental assistants who want to advance in the profession. There are currently four different DANB certifications and two to six component examinations within each certification:

  • Certified Restorative Functions Dental Assistant (CRFDA)
  • Certified Preventive Functions Dental Assistant (CPFDA)
  • Certified Orthodontic Assistant (COA)
  • Certified Dental Assistant (CDA)

State Requirements

Dental assistants must ensure they meet the requirements have been established by their state’s board of dentistry. State dental boards (often referred to as boards of dental examiners) regulate the practice of dentist assistants in most states; however, the requirements for registration or practice vary from state to state.

Some states require DANB national certification for dental assistants, while other states require dental assistants to graduate from a CODA-accredited training program and pass a licensing examination. Other states regulate dental assistants if they perform specific job duties, such as coronal polishing or x-rays, while still other states have no licensing or registration requirements at all.
