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 (diagnosing diseases in the head and neck through the use of imaging technologies); or dental public health specialists (promoting good dental health and preventing dental diseases within the community).
Work environment. Most dentists are solo practitioners, meaning that they own their own businesses and work alone or with a small staff. Some dentists have partners, and a few work for other dentists as associate dentists.
Most dentists work 4 or 5 days a week. Some work evenings and weekends to meet their patients' needs. The number of hours worked varies greatly among dentists. Most full-time dentists work between 35 and 40 hours a week. However, others, especially those who are trying to establish a new practice, work more. Also, experienced dentists often work fewer hours. It is common for dentists to continue in part-time practice well beyond the usual retirement age.
Dentists usually work in the safety of an office environment. However, work-related injuries can occur, such as those resulting from the use of hand-held tools when performing dental work on patients.
