Tennessee Dental Hygienist Requirements

Whether you’re just starting out or looking to transfer your license, understanding the education, licensing, and renewal requirements in Tennessee is essential. This page will help you learn everything you need to know about becoming a registered dental hygienist (RDH) in Tennessee.

To work as a dental hygienist in Tennessee, you must graduate from a Commission on Dental Accreditation (CODA) approved dental hygiene program. These programs typically take two to four years depending on if you decide to obtain an associate’s or bachelor’s degree. Typically coursework includes: 

• Oral anatomy and physiology
• Radiography and imaging
• Periodontology
• Dental materials and instruments
• Infection control and sterilization
• Clinical hands-on training

Tennessee dental hygienists must pass both written and clinical exams to qualify for licensure. The National Board Dental Hygiene Examination (NBDHE) is a written test administered by the Joint Commission on National Dental Examinations (JCNDE), assessing dental hygiene knowledge, patient care, and case-based scenarios. 

In addition to the NBDHE, candidates must pass a regional clinical board examination, which evaluates hands-on skills such as scaling, probing, and patient care techniques. Tennessee accepts clinical exams from various regional testing agencies, including CDCA-WREB-CITA (formerly ADEX), CRDTS (Central Regional Dental Testing Service), and SRTA (Southern Regional Testing Agency). Successfully passing these exams ensures that dental hygienists meet the state’s standards for professional competency and patient care.

Once you have graduated and passed the required exams, you must submit an application to the Tennessee Board of Dentistry. You’ll have to provide your proof of graduation, NBDHE and exam scores, CPR certification, background check, and application fee.

Dental hygienists in Tennessee must renew their licenses every two years and complete continuing education (CE) credits to stay up to date. Hygienists must submit 30 hours of continuing education credits, current CPR certification, and a renewal fee. 

Becoming a licensed dental hygienist in Tennessee is a rewarding path with strong job security, flexibility, and the opportunity to make a positive impact on patients’ oral health. If you’re ready to take the next step, explore accredited programs and begin your journey today!
