CaliforniaDental Hygienist License Requirements

CPR/BLS Certification Required

Background Check Required

Local anesthesia course (REQUIRED for initial RDH license)

Soft tissue curettage course (REQUIRED for initial RDH license)

Nitrous oxide course (REQUIRED for initial RDH license)

California is unique in multiple ways: it has a standalone Dental Hygiene Board separate from the Dental Board; it REQUIRES local anesthesia, soft tissue curettage, and nitrous oxide training for all initial RDH licenses (not optional); the RDHAP license is one of the nation's most independent practice models allowing treatment in non-traditional settings on a written prescription; and since 2024, California graduates can waive the clinical exam entirely if applying within 3 years. The state also requires dual background checks (both FBI and California DOJ) before any license can be issued.

California has its own independent Dental Hygiene Board (DHBC), separate from the Dental Board of California - one of only a few states with this distinction.

Local anesthesia, soft tissue curettage, and nitrous oxide courses are REQUIRED for initial RDH licensure - not optional like most states.

The RDHAP license is one of the most independent practice models in the nation - allows treatment in homes, schools, and facilities with only a written prescription from a dentist or physician.

Since January 1, 2024, graduates of California CODA-accredited programs can waive the clinical exam if they apply within 3 years of graduation.

Dual FBI and CA DOJ background checks are required; license cannot be issued until both are complete.

RDHAP requires a bachelor's degree in addition to dental hygiene education.

Dental hygienist scope of practice is expanding rapidly across states. Direct access, local anesthesia, nitrous oxide administration, and restorative functions vary significantly by state and may have changed since this data was last verified. Always confirm current scope with your state dental board.
