Dental Assistant

​Registered Dental Assistants are auxiliary​ staff who are deemed registered when the dentist employer report their names on the Online Dental License Renewal every biennium. If you are a dental assistant, you do not complete a registration. You only become a "registered dental assistant" if your employer dentist lists your name on the Dentist Online​ License Renewal.

The employer dentist will report the names of the employees as Registered Dental Assistants who have completed Board approved educational requirements for:

  • Coronal Polishing
  • Radiography
  • IV Placement

If you are a dentist employer, no action needs to be taken to register any auxiliary staff until you complete your Online Dental License Renewal.
