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

How to Become a Registered Dental Hygienist in Oklahoma

Oklahoma offers dental hygienists two distinct practice landscapes: the fast-growing suburban practices of Oklahoma City and Tulsa, and a robust tribal dental health infrastructure that serves one of the highest concentrations of Native American communities in the United States. Licensure is administered by the Oklahoma Board of Dentistry (OBD). This guide covers the full 2026 requirements.

Step 1: Complete an Accredited Dental Hygiene Program

Oklahoma requires completion of a dental hygiene program accredited by the Commission on Dental Accreditation (CODA). In-state options include Rose State College (Midwest City), Tulsa Community College, and the University of Oklahoma Health Sciences Center. Programs are competitive with limited enrollment, so applications should be submitted well in advance. Out-of-state graduates from CODA-accredited programs are also eligible to apply for Oklahoma licensure.

Step 2: Pass the NBDHE

The National Board Dental Hygiene Examination (NBDHE) administered by the JCNDE is required for Oklahoma licensure. This computer-based exam tests dental hygiene sciences, head and neck anatomy, pathology, radiology, and community oral health. Most candidates sit during their graduating semester. A passing score must be officially forwarded to the OBD as part of the license application.

Step 3: Pass a Clinical Examination

Oklahoma accepts two regional clinical board examinations:

• ADEX (American Board of Dental Examiners) — standardized live-patient clinical exam widely accepted across the U.S., with flexible testing locations and dates
• CRDTS (Central Regional Dental Testing Service) — live-patient clinical exam historically used in the South Central and Midwest region; testing sites are available in Oklahoma and surrounding states

Both exams cover patient assessment, scaling, radiography, and clinical documentation. Score reports must be submitted directly from the testing agency to the OBD.

Step 4: Apply for Your State License

After passing both board exams, submit your application to the Oklahoma Board of Dentistry. Required materials include:

• Completed OBD licensure application
• Official program transcripts (CODA-accredited)
• Official score reports from JCNDE and your clinical testing agency
• Current CPR/BLS certification
• Licensure fee — approximately $75–$100
• Background check

Visit the OBD website at ok.gov/dentistry for the current application packet and fee schedule.

Continuing Education Requirements

Oklahoma RDHs must complete 20 CE hours per two-year renewal cycle. The OBD does not currently mandate specific subject-matter requirements for the full 20 hours, but recommends infection control and current clinical practice updates. CE providers must be OBD-approved or recognized by an accredited national dental CE body. Keep records of all CE completions for a minimum of three years.

Oklahoma Dental Hygienist Salary Ranges

Oklahoma's lower cost of living relative to coastal states translates to moderate base salaries, but compensation has trended upward in recent years as demand outpaces the supply of new graduates:

• Entry-level (0–2 years): $50,000–$60,000/year
• Mid-career (3–7 years): $60,000–$72,000/year
• Experienced (8+ years): $72,000–$84,000/year
• Oklahoma City metro: suburban Edmond and Yukon practices often pay top of range; DSO presence growing
• Tulsa metro: comparable to OKC; strong demand in South Tulsa corridors
• Tribal health programs: may offer federal-equivalent pay scales plus benefits through 638 contracts; IHS rates competitive with private sector
