What Does a Dental Hygienist Do?

A dental hygienist is an oral health professional who helps prevent and treat tooth decay, gum disease, and other oral health problems. Most dental hygienists work in dentists’ offices, but some work in community and public health clinics, hospitals, schools, managed care organizations, and nursing homes or long-term care facilities. Some hygienists also teach courses at postsecondary institutions or conduct research in the field of dentistry and oral health.

A hygienist typically spends most of his or her time cleaning patients’ teeth and performing other clinical duties. This includes collecting a patient’s medical and dental history, as well as conducting an examination of the head, mouth, and neck to look for signs of disease or injury. The hygienist may also apply sealants—an acrylic-like material that protects the chewing surfaces of young children’s teeth to help prevent cavities—and fluoride treatments, both of which are helpful in slowing tooth decay.

Hygienists also take X-rays of the mouth to provide a more comprehensive view of the teeth, bones, and supporting structures. They may also administer local anesthesia—which numbs the mouth—for certain procedures.

A career as a dental hygienist requires a minimum of an associate degree from an accredited program, and most states require licensure.
