What Does a Dental Hygienist Do?

Dental hygienists are preventive oral health professionals who graduate from an accredited dental hygiene program and obtain a license to practice. Hygienists perform clinical, research, educational, and administrative services supporting total health through optimum oral care.

Oral health screenings

Hygienists use a probe to check the depth of your gum pockets and look for signs of disease like periodontitis (gum disease). They also conduct routine oral cancer exams by gently examining the inside of your mouth for any unusual growths or lesions.

Teeth cleaning

The first thing a hygienist will do is take a patient’s dental and medical history and then clean the teeth using a professional polisher to remove surface stains, plaque, and tartar from the teeth and gum line. They may also use tools to clean under the gums where your toothbrush can’t reach.

X-rays

Dental hygienists can take a variety of dental X-rays, including bite-wing and panoramic X-rays. These X-rays give dentists a clearer view of your tooth roots, supporting bone, sinuses, nerves, and other structures.

During an examination, your hygienist can advise you on how to keep your teeth healthy between visits and help you develop good habits. They can teach you how to brush and floss correctly and give advice on diet and nutrition. They can also apply fluoride and/or sealants on the biting surfaces of children’s permanent back teeth to help protect them from decay. Hygienists can also recommend smoking cessation programs and can give special instructions about caring for dentures or braces.
