How to Get a Dental Hygienist License in San Diego, California

To become a Registered Dental Hygienist (RDH) in California, you must: (1) graduate from a CODA-accredited dental hygiene program, (2) pass the National Board Dental Hygiene Examination (NBDHE), (3) pass a clinical licensing exam such as the ADEX (or qualify for the clinical exam exemption as a recent California graduate), (4) pass the California Law and Ethics Examination administered by PSI, (5) complete approved courses in local anesthesia, nitrous oxide, and soft tissue curettage, and (6) submit an application with fingerprints and fees to the Dental Hygiene Board of California (DHBC) through the BreEZe online portal.

The entire process typically takes 2.5 to 4 years. An associate degree program at a California community college takes 2-3 years (including prerequisites), while a bachelor's program takes about 4 years. After graduating, the exam and licensing process adds approximately 2-4 months. Many students complete prerequisite courses like anatomy and chemistry before entering the dental hygiene program, so total time may vary depending on how quickly you fulfill prerequisites.

Total costs range from approximately $20,000 to $25,000. The major expense is tuition for a CODA-accredited dental hygiene program, which ranges from roughly $17,000 to $23,000 at California community colleges (including instruments, supplies, and fees). Exam fees add approximately $1,750 total: $600 for the NBDHE and $1,150 for the ADEX clinical exam. The DHBC application fee is $100 and the initial license issuance fee is $100. You will also need to budget for CPR certification, Live Scan fingerprinting, and study materials.

Yes. California offers a Licensure by Credential (LBC) pathway for dental hygienists who have held an active RDH license in another state for at least five years with no disciplinary actions. LBC applicants must still pass the California Law and Ethics Examination but may be exempt from taking a clinical exam. You must apply through the DHBC and provide verification of your out-of-state license, proof of education from a CODA-accredited program, and passing NBDHE scores. Contact the DHBC at (916) 263-1978 for specific eligibility questions.

No, a bachelor's degree is not required. An associate degree from a CODA-accredited dental hygiene program is the minimum educational requirement for RDH licensure in California. However, a bachelor's degree can open doors to careers in education, public health, research, and management. Several California universities offer bachelor's completion programs for RDHs who already hold an associate degree, including programs at the University of the Pacific and West Coast University.

The ADEX dental hygiene examination is the clinical licensing exam accepted by California. Administered by CDCA-WREB-CITA, it consists of a computer-based simulation component and a Simulated Patient Treatment Clinical Examination (SPTCE) that tests your clinical skills on a manikin, including calculus detection and removal, periodontal probing accuracy, and tissue management. The exam fee is approximately $1,150 plus a facility fee. Important: As of January 1, 2024 (under AB 1257), graduates of California CODA-accredited programs who apply for licensure within three years of graduation may be exempt from this clinical examination.

California dental hygienists earn among the highest salaries in the nation. According to the Bureau of Labor Statistics, the average annual salary for RDHs in California is approximately $118,330 (about $56.89 per hour). Salaries vary by region: the San Francisco Bay Area and San Jose metros tend to pay the highest, while areas like the Central Valley average closer to $89,000-$95,000 per year. With approximately 25,000 employed dental hygienists and projected 7% job growth through 2034, California offers strong earning potential and job security for RDHs.

California RDHs must complete 25 hours of continuing education (CE) every two years to renew their license. Up to 12.5 hours may be completed through home study or online courses. At minimum, 2 hours must cover infection control and 2 hours must cover the California Dental Practice Act. CE courses must be from providers approved by the Dental Board of California, the ADA's CERP program, or the AGD's PACE program. No CE is required for your first renewal period after initial licensure. The biennial renewal fee is approximately $300.
