dental hygienist a dental health specialist whose primary concern is nonsurgical periodontal therapy, maintenance of dental health, and prevention of oral disease. Patient education in proper brushing and interdental cleaning (such as with floss or a water jet) is also a major responsibility of the dental hygienist. In most states the dental hygienist must work under the general supervision of a licensed dentist.

Dental hygiene is also offered in bachelor's and master's degree programs. The registered dental hygienist (RDH) must have successfully completed the written and practical examinations required by the state in which he or she wishes to practice.
