How to Get Your Dental Hygienist License in California (2026)

How to Become a Registered Dental Hygienist in California

California is the nation's largest dental hygienist market and one of the most regulated. The state has its own examination requirements that differ meaningfully from most other states, and it offers an expanded scope of practice, including a local anesthesia permit, unavailable in many jurisdictions. The Dental Board of California (DBC) regulates RDH licensure.

Step 1: Complete an Accredited Dental Hygiene Program

Graduation from a CODA (Commission on Dental Accreditation)-accredited dental hygiene program is required. California has among the most CODA-accredited dental hygiene programs of any state, available through community colleges and universities across the state, including Diablo Valley College, West Los Angeles College, Cypress College, and many others. Most award an Associate of Science (AS) or Associate of Applied Science (AAS) in Dental Hygiene. Bachelor's completion and BSDH programs are available for career advancement. Confirm CODA accreditation status before enrolling.

Step 2: Pass the NBDHE (National Board Dental Hygiene Examination)

California requires a passing NBDHE score for all applicants. The 350-question computer-based exam covers dental hygiene sciences, biomedical sciences, and patient case studies. It is administered at Pearson VUE test centers through the JCNDE. The exam fee is approximately $450. A passing score is required before California will allow you to sit for the state-required clinical examination.

Step 3: Pass a Clinical (Practical) Examination

This is critical and different from most states. California accepts the CSCE (California Standard Clinical Examination), which is administered through the ADEX system but specifically designed for California, however, California does not accept the standard WREB (Western Regional Examining Board) that neighboring western states use. This means dental hygienists who tested with WREB for Oregon or Nevada licensure may need to re-test for California. Verify current accepted clinical examination requirements with the Dental Board of California before scheduling, as this is a common source of confusion for applicants.

The CSCE is a patient-based clinical examination evaluating periodontal instrumentation, patient assessment, radiographic technique, and infection control compliance.

Step 4: Apply for Your State License

Submit your application to the Dental Board of California. Application fees are $200 or more, among the higher state application fees nationally. Required documentation includes:

• Official transcripts from your CODA-accredited dental hygiene program
• NBDHE passing score verification
• CSCE passing score verification
• Criminal background check (LiveScan fingerprinting in California)
• Current CPR/BLS certification
• Completed RDH application and fee payment

California has a notoriously complex application process. Apply early, make sure all documents are certified and complete, and track your application status actively through the DBC portal. Initial license processing can take several months during high-volume periods.

Optional, Local Anesthesia Permit: California allows dental hygienists to obtain a separate local anesthesia permit after licensure. This requires completion of a DBC-approved local anesthesia course at a CODA-accredited institution and passing an examination. RDHs with this permit command a salary premium in many California markets.

Continuing Education Requirements

California dental hygienists must complete 25 hours of continuing education every two years. California has specific mandatory CE topic requirements, including 8 hours covering infection control and OSHA standards. This is one of the highest infection-control CE mandates in the country. Additional mandatory topics may include licensee safety, cultural competency, and implicit bias training per recent DBC rule changes. Verify the current mandatory topic list on the Dental Board of California website, as requirements are subject to legislative updates.

California Dental Hygienist Salary Ranges

California dental hygienists are among the highest-paid in the country. In the Los Angeles and Bay Area markets, annual compensation typically ranges from $80,000 to $105,000, with experienced hygienists in high-demand practices or specialty settings earning above that range. The Central Valley and rural inland California areas are lower, generally $65,000-$82,000. High cost of living tempers the real-wage premium, but California RDH wages remain nationally competitive on a nominal basis.
