Dentists diagnose, prevent and treat teeth and tissue
problems. They remove 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 provide instruction on diet, brushing,
flossing, use of fluorides and other aspects of dental care. They administer
anesthetics and write prescriptions for antibiotics and other medications.
Dentists use a variety of equipment, including X-ray
machines, drills and instruments, such as mouth mirrors, probes, forceps, brushes
and scalpels. They 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 buying equipment and supplies.
They may employ and supervise dental hygienists, dental assistants, dental laboratory
technicians and receptionists.
Most dentists are general practitioners, handling
a variety of dental needs. Other dentists practice in one of nine specialty
areas. Orthodontists, the largest group of specialists, straighten teeth by
applying pressure to the teeth with braces or retainers. The next largest group,
oral and maxillofacial surgeons, operate on the mouth and jaws.
The remainder may specialize as pediatric dentists
(focusing on dentistry for children); periodontists (treating gums and bone
supporting the teeth); prosthodontists (replacing missing teeth with permanent
fixtures, such as crowns and bridges, or removable fixtures, such as dentures);
endodontists (performing root canal therapy); public health dentists (promoting
good dental health and preventing dental diseases within the community); oral
pathologists (studying oral diseases); or oral and maxillofacial radiologists
(diagnosing diseases in the head and neck through the use of imaging technologies).
Most dentists work four or five days a week. Most
dentists 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.
Training and qualifications
All 50 states and the District of Columbia require
dentists to be licensed. In most states, a candidate must graduate from a dental
school accredited by the American Dental Association's Commission on Dental
Accreditation and pass written and practical examinations to qualify for a license.
Currently, about 17 states require dentists to obtain
a specialty license before practicing as a specialist. Requirements include
two to four years of postgraduate education and, in some cases, completion of
a special state examination. Dentists who want to teach or do research usually
spend an additional two to five years in advanced dental training, in programs
operated by dental schools or hospitals.
Most dental students have at least a bachelor's
degree. Pre-dental education emphasizes coursework in the sciences. All dental
schools require applicants to take the Dental Admissions Test (DAT). Dental
school usually lasts four academic years. Most dental schools award the degree
of Doctor of Dental Surgery (DDS). The rest award an equivalent degree, Doctor
of Dental Medicine (DMD).
Dentistry requires diagnostic ability and manual
skills. Dentists should have good visual memory, excellent judgment of space
and shape, a high degree of manual dexterity and scientific ability. Good business
sense, self-discipline and communication skills are helpful for success in private
practice. High school and college students who want to become dentists should
take courses in biology, chemistry, physics, health and mathematics.
Job outlook
Employment of dentists is expected to grow more
slowly than the average for all occupations through 2010. Job prospects should
be good if the number of dental school graduates does not grow significantly,
thus keeping the supply of newly qualified dentists near current levels.
Demand for dental care should grow substantially
through 2010. As members of the baby-boom generation advance into middle age,
a large number will need maintenance on complicated dental work, such as bridges.
In addition, elderly people are more likely to retain their teeth than were
their predecessors, so they will require much more care than in the past. The
younger generation will continue to need preventive checkups despite treatments
such as fluoridation of the water supply, which decreases the incidence of tooth
decay.
Dental care will focus more on prevention, including
teaching people how better to care for their teeth. But dentists are likely
to hire more dental hygienists and dental assistants to handle routine services.
Earnings
Dentists held about 152,000 jobs in 2000. Almost
all dentists work in private practice. Median annual earnings of salaried dentists
were $129,030 in 2000. Earnings vary according to number of years in practice,
location, hours worked and specialty.
Self-employed dentists in private practice tend
to earn more than do salaried dentists. A relatively large proportion of dentists
is self-employed.
