Licensing and Certification

After completing an accredited clinical dental hygienist program, graduates must obtain licensure to practice. Every state requires dental hygienists to be licensed; requirements vary by state.

National Board Dental Hygiene Examination

The National Board Dental Hygiene Examination is a crucial milestone for aspiring dental hygienists. Administered by the Joint Commission on National Dental Examinations, the NBDHE assesses the knowledge and skills necessary for safe and effective dental hygiene practice. To take the exam, you must ensure you meet the eligibility requirements and then submit an application to the Joint Commission on National Dental Examinations (JCNDE). You will need to either have your program director confirm your eligibility or submit proof that you graduated from the program. Passing the NBDHE is essential for licensure in all states, ensuring that dental hygienists meet national standards of competency. Pass the National written examination.

State Clinical Examination

Each state requires dental hygienists to pass a state-specific clinical examination to demonstrate their practical skills. These exams typically involve performing dental hygiene procedures on patients under the supervision of examiners. The clinical examination ensures that candidates can apply their theoretical knowledge in real-world scenarios, maintaining high standards of patient care and safety. Pass the National written examination. Once the WREB application is deemed complete, a letter will be sent to the applicant containing information regarding the written RDH law and ethics examination administered by the computer-based testing center (PSI).

State Licensure

In most states, a degree from an accredited dental hygiene program and passing written and clinical examinations are required for licensure. To obtain state licensure as a dental hygienist in the US, candidates must:
