Dentists diagnose and treat problems with teeth and tissues in the mouth, along with giving advice and administering care to help prevent future problems. They provide instruction on diet, brushing, flossing, the use of fluorides, and other aspects of dental care. They remove tooth decay, fill cavities, examine x rays, place protective plastic sealants on children's teeth, straighten teeth, and repair fractured teeth. They also perform corrective surgery on gums and supporting bones to treat gum diseases. Dentists extract teeth and make models and measurements for dentures to replace missing teeth. They also administer anesthetics and write prescriptions for antibiotics and other medications.
Dentists use a variety of equipment, including x-ray machines, drills, mouth mirrors, probes, forceps, brushes, and scalpels. Lasers, digital scanners, and other computer technologies also may be used. Dentists wear masks, gloves, and safety glasses to protect themselves and their patients from infectious diseases.
Dentists in private practice oversee a variety of administrative tasks, including bookkeeping and the buying of equipment and supplies. They may employ and supervise dental hygienists, dental assistants, dental laboratory technicians, and receptionists. (These occupations are described elsewhere in the Handbook.)
Most dentists are general practitioners, handling a variety of dental needs. Other dentists practice in any of nine specialty areas. Orthodontists, the largest group of specialists, straighten teeth by applying pressure to the teeth with braces or other appliances. The next largest group, oral and maxillofacial surgeons, operates on the mouth, jaws, teeth, gums, neck, and head. The remainder may specialize as pediatric dentists (focusing on dentistry for children and special-needs patients); periodontists (treating gums and bone supporting the teeth); prosthodontists (replacing missing teeth with permanent fixtures, such as crowns and bridges, or with removable fixtures such as dentures); endodontists (performing root-canal therapy); oral pathologists (diagnosing oral diseases); oral and maxillofacial radiologists ...
