All dental assistants must have a permit from the Oklahoma Board of Dentistry before working chairside, as of November 1, 2025. Each expanded duty then takes its own separate permit. This guide comes from DentalReady's fifty-state requirements research: what you can do from day one in Oklahoma, the certifications that expand your duties, and the realistic path in. Rules change, so the Oklahoma Board of Dentistry link at the bottom is always the final word.
