Dental hygienists provide preventative dental care in addition to serving as an important bridge between the dentist and patient. Hygienists perform routine oral health screenings and identify issues such as gum disease and cavities so the dentist can address them before they worsen.

A dental hygienist’s duties also include taking and processing dental X-rays, which enable the dentist to view the tooth roots, supporting bone, sinuses, nerves, and other hidden structures; performing root-planing as a periodontal treatment; placing and carving filling materials, temporary crowns, and periodontal dressings; administering local anesthesia and nitrous oxide; and applying fluoride and sealant to help prevent tooth decay between appointments. Hygienists also educate patients on proper brushing, flossing, and eating habits to maintain good dental hygiene.

What Does a Dental Hygienist Do? Your Guide to Preventive Care

Regular professional cleanings to remove plaque and tartar, combined with looking after teeth and gums properly at home, will significantly slow the onset of gum disease. In addition to cleaning, dental hygienists can recommend specialist toothpaste and electric or ‘power’ toothbrushes, mouthwashes, and other products to aid good oral health.

Dental hygienists must be detail-oriented and have excellent interpersonal communication skills to serve as an effective bridge between the dentist and patient, helping to explain complex procedures in a way that makes them understandable. They must be comfortable working closely with the teeth and gums, as well as using small instruments in a limited space. They must be able to work as part of a team, including other healthcare professionals.
