Hygienists examine patients' teeth and gums, recording the presence of diseases or abnormalities.
Dental hygienists also help patients develop and maintain good oral health. For example, they may explain the relationship between diet and oral health, inform patients how to select toothbrushes, and show patients how to brush and floss their teeth. Dental hygienists use hand and rotary instruments to clean teeth, x-rays machines to take dental pictures, syringes with needles to administer local anesthetics, and models of teeth to explain oral hygiene. Job Description Dental Assistants perform a variety of patient care, office and laboratory duties. They work at chairside as dentists examine and treat patients.
