Nature of the Work Dentists diagnose, treat and prevent disorders of the teeth and tissues of the mouth, as well as related areas of the head and neck. In general practice the emphasis has changed from correction of teeth or mouth problems to the prevention of these problems. Most dentists work in private practice, but they may also be employed in hospitals, clinics, public health facilities or universities.
Most dentists are general practitioners who typically are fixing teeth.
They examine patients' teeth, gums and jaws to diagnose disease, injury and decay. They remove decay and fill cavities. They clean teeth and instruct patients on oral hygiene, covering topics such as diet, brushing, flossing and the use of fluorides. They extract teeth and make molds and measurements for bridges and for dentures to replace the missing teeth. They administer anesthetics and write prescriptions for antibiotics and other medications.
