California is one of the highest-paying states in the country for dental hygienists, with average salaries exceeding $127,000 per year. The state is also home to 25 CODA-accredited dental hygiene programs and a large, growing population that drives consistent demand for preventive dental care. Whether you’re a California resident starting your education or a licensed hygienist considering a move to the Golden State, this guide covers every step of the process — including the significant licensing changes introduced by Assembly Bill 1257, which took effect January 1, 2024.
Dental Hygienist Requirements in California
California’s dental hygiene profession is regulated by the Dental Hygiene Board of California (DHBC), which operates under the Department of Consumer Affairs. The DHBC issues Registered Dental Hygienist (RDH) licenses, approves educational programs, administers the California Law and Ethics exam, and enforces continuing education requirements.
To become a licensed dental hygienist in California, you must meet all of the following requirements:
- Graduate from a dental hygiene program that is both CODA-accredited and DHBC-approved
- Pass the National Board Dental Hygiene Examination (NBDHE)
- Pass a clinical licensing examination (WREB, ADEX, or CRDTS) — or graduate from a California-approved program on or after January 1, 2024 (which satisfies the clinical exam requirement under AB 1257)
- Pass the California Dental Law and Ethics examination (computer-based, administered by PSI)
- Complete approved coursework in local anesthesia, soft tissue curettage, and nitrous oxide-oxygen analgesia
- Maintain current BLS (Basic Life Support) certification
- Pass a Live Scan fingerprint background check
- Submit your application and fees through the BreEZe online licensing system
California also offers a Licensure by Credential (LBC) pathway for dental hygienists who have been licensed and actively practicing in another state for at least five years with a minimum of 750 clinical practice hours per year.
Step-by-Step Guide to Becoming a Dental Hygienist in California
Step 1: Complete Your Prerequisites
Before entering a dental hygiene program, you’ll need a high school diploma or GED plus several college-level prerequisite courses. Most California programs require courses in general biology, anatomy and physiology, microbiology, general chemistry, English composition, and college-level math. Some programs also require psychology or speech communication. Prerequisites typically take one to two semesters to complete if you’re starting from scratch, though many students complete them alongside their general education requirements.
California’s dental hygiene programs are competitive, so strong grades in your prerequisite science courses are essential.
Step 2: Graduate from a CODA-Accredited, DHBC-Approved Dental Hygiene Program
Enroll in and graduate from a dental hygiene program that holds both CODA accreditation and DHBC approval. California has approximately 25 accredited programs, offering associate degrees, bachelor’s degrees, and in some cases, bachelor’s completion pathways for working RDHs.
Most students pursue an associate degree, which typically takes about two to three years of full-time study (not counting prerequisites). Programs include rigorous coursework in dental anatomy, periodontology, radiology, pharmacology, dental materials, community dental health, and clinical dental hygiene. You’ll also complete extensive supervised clinical hours working with real patients.
This is a critical change introduced by AB 1257: if you graduate from a California CODA-accredited and DHBC-approved program on or after January 1, 2024, your graduation satisfies the clinical examination requirement for RDH licensure. You no longer need to take a separate clinical exam (WREB, ADEX, or CRDTS). This significantly streamlines the licensing process for California graduates.
Step 3: Complete Additional Required Coursework
California requires all RDH applicants to have completed Board-approved courses in three areas: administration of local anesthesia, soft tissue curettage, and nitrous oxide-oxygen analgesia. Most California dental hygiene programs incorporate these into their curriculum. If your program did not include one or more of these, you’ll need to complete them separately through an approved provider before applying for licensure.
Step 4: Pass the National Board Dental Hygiene Examination (NBDHE)
The NBDHE is a 350-question, computer-based written exam administered by the Joint Commission on National Dental Examinations (JCNDE) at Pearson VUE testing centers. The exam covers biomedical sciences, clinical dental hygiene, and community health principles. You need a scaled score of 75 or higher to pass. Most students take the NBDHE during their final semester of their dental hygiene program. The exam fee is $600.
Step 5: Pass a Clinical Licensing Examination (If Required)
If you graduated from a California program before January 1, 2024, or if you graduated from an out-of-state program, you must pass a Board-approved clinical examination. California accepts results from the WREB (Western Regional Examining Board), ADEX (American Board of Dental Examiners), and CRDTS (Central Regional Dental Testing Service) exams. Clinical exam results must be within three years of your application date.
If you graduated from a California CODA/DHBC-approved program on or after January 1, 2024, this step is not required — your graduation satisfies the clinical exam requirement.
Step 6: Pass the California Law and Ethics Examination
All RDH applicants must pass the California Dental Law and Ethics exam, a computer-based test administered through PSI testing centers. This exam covers California-specific dental hygiene laws, regulations, and ethical standards. You’ll receive eligibility information from the DHBC after your application is deemed complete.
Step 7: Apply for Your RDH License Through BreEZe
Submit your application online through California’s BreEZe licensing system at breeze.ca.gov. Upload your proof of education, NBDHE scores, clinical exam results (if applicable), Live Scan fingerprint background check, BLS certification, and coursework completion certificates. Pay the $100 application fee. The DHBC’s average processing time is approximately 30 business days after receiving a complete application.
Step 8: Maintain Your License
Once licensed, you must renew your RDH license every two years through BreEZe. The biennial renewal fee is $300. You’re required to complete 25 hours of continuing education every two years, including a minimum of 2 hours in infection control and 2 hours in the California Dental Practice Act. Up to 12.5 of the 25 hours may be completed through home study (self-study) courses.
Education & Training Programs in California
California has approximately 25 CODA-accredited dental hygiene programs spread across the state, primarily at community colleges. This gives California one of the largest selections of accredited programs in the country.
Notable programs include:
- Pasadena City College (Los Angeles area) — Associate degree program with CODA accreditation. Two-year program with strong clinical training in the greater LA region.
- Fresno City College (Central Valley) — Offers both an associate degree and a bachelor’s degree completion pathway. CODA-accredited with full approval.
- Santa Rosa Junior College (North Bay) — Affiliated with UCSF School of Dentistry. CODA-accredited program with strong clinical rotations and community health focus.
- West Los Angeles College (LA area) — Community college program offering an associate degree in dental hygiene.
- Chabot College (East Bay / San Francisco metro) — CODA-accredited associate degree program serving the Bay Area.
- Foothill College (South Bay / Silicon Valley) — Associate degree program with strong placement rates in the high-paying Silicon Valley market.
Programs at the University of the Pacific and Loma Linda University offer bachelor’s degree options for students seeking additional career flexibility in education, research, or public health roles.
When choosing a program, prioritize CODA accreditation and DHBC approval (both are required for California licensure), NBDHE pass rates, clinical facility quality, and program cost. Community college programs are the most affordable option, with in-state tuition typically ranging from $5,000 to $15,000 for the dental hygiene coursework (excluding prerequisites and fees).
California Licensing Process
Here is a summary of the RDH licensing process in California:
- Graduate from a CODA-accredited, DHBC-approved dental hygiene program
- Complete required coursework in local anesthesia, soft tissue curettage, and nitrous oxide
- Pass the NBDHE (written national exam, $600)
- Pass a clinical exam — WREB, ADEX, or CRDTS (unless you graduated from a California program on or after January 1, 2024)
- Pass the California Law and Ethics exam (computer-based, PSI)
- Complete a Live Scan fingerprint background check
- Maintain current BLS certification
- Submit your application through BreEZe (breeze.ca.gov) with all required documents
- Pay the $100 application fee
- Receive your RDH license (approximately 30 business days after complete application)
California also offers three license categories: RDH (Registered Dental Hygienist), RDHAP (Registered Dental Hygienist in Alternative Practice, which allows independent practice in certain settings), and RDHEF (Registered Dental Hygienist in Extended Functions). The standard RDH license is the entry-level credential that the vast majority of new graduates pursue.
How Long Does It Take to Become a Dental Hygienist in California?
| Milestone | Estimated Timeline |
|---|---|
| High school diploma or GED | Prerequisite (already completed) |
| College prerequisite courses | 1–2 semesters (6–12 months) |
| Associate degree in dental hygiene | 2–3 years |
| NBDHE exam | Taken during final semester |
| Clinical exam (if required) | Taken around graduation |
| California Law and Ethics exam | Taken after application deemed complete |
| DHBC license application and processing | ~30 business days |
| Total (associate degree path) | 3–4 years |
| Total (bachelor’s degree path) | 4–5 years |
Most California dental hygiene students complete their associate degree and begin working within three to four years of starting their prerequisite coursework. The AB 1257 change eliminating the separate clinical exam requirement for California graduates has shortened the licensing timeline slightly, since graduates no longer need to schedule and pass a regional clinical exam before applying.
Cost Breakdown
| Expense | Estimated Cost |
|---|---|
| Associate degree tuition (community college, in-state) | $5,000–$15,000 |
| Bachelor’s degree tuition (university) | $20,000–$60,000 |
| Prerequisites (community college, ~30 units) | $1,500–$4,000 |
| Textbooks, instruments, and clinical supplies | $2,000–$5,000 |
| NBDHE exam fee | $600 |
| Clinical exam fee (WREB/ADEX/CRDTS, if required) | $600–$1,200 |
| California Law and Ethics exam | ~$60–$100 |
| Live Scan background check | $50–$80 |
| BLS certification | $50–$100 |
| DHBC application fee | $100 |
| Biennial license renewal | $300 |
| Total estimated cost (associate degree, community college) | $10,000–$26,000 |
California community college programs are remarkably affordable compared to the salary they lead to. With in-state community college tuition at $46 per unit, the dental hygiene program coursework itself may cost as little as $3,000–$5,000 in tuition — though fees, instruments, and clinical supplies add significantly to the total. Given that the average California dental hygienist salary exceeds $127,000 per year, the return on investment for a community college dental hygiene education is among the strongest of any healthcare career.
