Dentists | What Do They Do?

Dentists typically do the following:

• Remove decay from teeth and fill cavities
• Repair cracked or fractured teeth and remove teeth
• Straighten teeth to correct bite issues
• Place sealants or whitening agents on teeth
• Give anesthetics to keep patients from feeling pain during procedures
• Write prescriptions for antibiotics or other medications
• Examine x rays of teeth, gums, the jaw, and nearby areas for problems
• Make models and measurements for dental appliances, such as dentures, to fit patients
• Teach patients about diet, flossing, use of fluoride, and other aspects of dental care

Dentists use a variety of equipment, including x-ray machines, drills, mouth mirrors, probes, forceps, brushes, and scalpels. They also use lasers, digital scanners, and other computer technologies.

Dentists in private practice also oversee a variety of administrative tasks, including bookkeeping and buying equipment and supplies. They employ and supervise dental hygienists, dental assistants, dental laboratory technicians, and receptionists.

Most dentists are general practitioners and handle a variety of dental needs. Other dentists practice in one of nine specialty areas:

Dental public health specialists promote good dental health and the prevention of dental diseases in specific communities.

Endodontists perform root-canal therapy, by which they remove the nerves and blood supply from injured or infected teeth.

Oral and maxillofacial radiologists diagnose diseases in the head and neck through the use of imaging technologies.

Oral and maxillofacial surgeons operate on the mouth, jaws, teeth, gums, neck, and head, including procedures such as surgically repairing a cleft lip and palate or removing impacted teeth.

Oral pathologists diagnose oral diseases, such as oral cancer or oral lesions (bumps or ulcers in the mouth).

Orthodontists straighten teeth by applying pressure to the teeth with braces or other appliances.

Pediatric dentists focus on dentistry for children and special-needs patients.

Periodontists treat the gums and bone supporting the teeth.

Prosthodontists replace missing teeth with permanent fixtures, such as crowns and bridges, or with removable fixtures such as dentures.
