How to Become a Dental Assistant in Oklahoma

All dental assistants in Oklahoma must obtain a Dental Assistant Permit issued by the Oklahoma Board of Dentistry within 30 days of being hired to work in a dental office. Oklahoma law generally permits a dentist to delegate duties to dental assistants as long as the latter has had adequate office-based training by the supervising dentist and is aware of the requirements as well as responsibilities of each duty.

There are a few exceptions to this that require dental assistants to meet specific requirements to receive an Expanded Duty Permit. Such permits are issued in the following four areas:

  • Radiation safety and protection
  • Coronal polishing and topical fluoride
  • Placement of pit and fissure sealants
  • Assisting in the administration of nitrous oxide
