Dental hygienists help people maintain healthy smiles and healthy bodies

The dental hygiene profession was founded more than 100 years ago, in 1913, and today there are more than 185,000 registered dental hygienists across the U.S. who provide professional oral health care to help people maintain healthy smiles and healthy bodies.

Dental hygienists are primary health care providers. Their role entails providing several health and oral health assessments and evaluations to determine oral health status and links between oral and systemic health. After the oral health assessments, the dental hygienist determines the dental hygiene diagnosis, and along with the dentist and the patient determines the best course of treatment to prevent or treat oral disease.

Preventive and therapeutic oral hygiene can include removing hard and soft deposits from teeth using hand instruments, ultrasonic tools, air polishers, and possibly lasers. Additionally, they may apply fluoride,sealants, anesthetic, nitrous oxide, and oral medications. Dental hygienists obtain radiographs (x-rays) of teeth and the surrounding bone to further determine oral disease such as dental caries, bone loss, and hard deposits below the gum line.

Dental hygienists help patients develop and
maintain good oral health by:

  • Educating patients on how to care for their teeth.
  • Helping patients to identify life style habits, such as soda sipping, that might be causing dental caries.
  • Providing information and resources for patients to quit using tobacco or vaping products.
  • Performing oral cancer screenings and educate patients on oral cancer risk factors, signs, and symptoms.
  • Encouraging patients to adopt healthy eating habits.
  • Providing referrals to allied health professionals and specialized oral health care as needed.
