Dental Hygienists
Overview
Administer oral hygiene care to patients. Assess patient oral hygiene problems or needs and maintain health records. Advise patients on oral health maintenance and disease prevention. May provide advanced care such as providing fluoride treatment or administering topical anesthesia.
What do they do?
Dental hygienists examine patients for signs of oral diseases, such as gingivitis, and provide preventive care, including oral hygiene. They also educate patients about oral health.
Dental hygienists use many types of tools—including hand, power, and ultrasonic tools—in their work. In some cases, they use lasers. Hygienists remove stains with an air-polishing device, which sprays a combination of air, water, and baking soda. They polish teeth with a power tool that works like an automatic toothbrush. Hygienists also use x-ray machines to take pictures to check for tooth or jaw problems.
Dental hygienists talk to patients about ways to keep their teeth and gums healthy. For example, they may explain the relationship between diet and oral health. They may also advise patients on how to select toothbrushes and other oral care devices.
The tasks hygienists may perform, and the extent to which they must be supervised by a dentist, vary by state and by the setting in which the dental hygienist works. A few states allow hygienists with additional training, sometimes called dental therapists, to provide some restorative services, such as extracting primary teeth and placing temporary crowns.
How to become one
Dental hygienists typically need an associate’s degree in dental hygiene; they may also get a bachelor’s degree. Master’s degree programs in dental hygiene are available but are relatively uncommon. A bachelor’s or master’s degree usually is required for research, teaching, or clinical practice in public or school health programs.
Dental hygiene programs are often found in community colleges, technical schools, and universities. The Commission on Dental Accreditation, part of the American Dental Association, accredits more than 300 dental hygiene programs.
Programs typically take 3 years to complete and offer laboratory, clinical, and classroom instruction. Areas of study include anatomy, medical ethics, and periodontics, which is the study of gum disease.
High school students interested in becoming dental hygienists should take courses in biology, chemistry, and math. Most dental hygiene programs also require applicants to complete prerequisites, which often include college-level courses. Specific requirements vary by school.
