What Is a dental hygienist?

A dental hygienist is a licensed health care professional, oral health educator, and clinician who, as a cotherapist with the dentist, provides preventive, educational, and therapeutic services supporting total health for the control of oral diseases and the promotion of oral health. A registered dental hygienist has graduated from a minimum two-year college program that includes classroom studies and extensive supervised clinical experience. A dental hygienist also must pass a national written exam and a comprehensive state clinical exam to earn the RDH license.

Generally, the dental hygienist may work in general and specialty oral health practices. Other areas of employment include programs for research, professional education, and community health; hospital and institutional care of disabled persons; federal programs, such as the armed services; or other health service locations as specified in statute or as authorized by the state board of dentistry.
