Dentists are health care professionals who specialize in caring for the teeth, gums, and other tissues of the mouth. Dental care isn’t just about having clean teeth and a beautiful smile. Regular visits can ward off painful tooth decay, prevent infections, and help catch conditions like cancer and diabetes early.

About 80 percent of dentists practice general dentistry. However, those with advanced education and training can also practice a dental specialty like surgery, pathology, orthodontics, pediatric dentistry, or dental public health.

Dentists play a very important role in their patients’ overall health. Left untreated, conditions like gum disease can allow bacteria in the mouth to spread through the body, resulting in a serious infection. Dentists may also be the first health professionals to notice signs of systemic conditions like cancer, diabetes, and heart and kidney disease. Finally, good dental care helps to keep chronic health problems like diabetes, heart disease, HIV/AIDS, and osteoporosis under control.

Choosing a career in dentistry has many benefits. Dentists do a great deal of good for their patients by relieving pain, restoring function, and helping them look their best. A career in dentistry provides a great deal of flexibility and autonomy, even for new professionals. And with a wide range of practice options and specialties from which to choose, dentists can shape their careers as they see fit.

Workplace Details

As of 2010, 86 percent of dentists were self-employed and working in solo or group practices. However, dentists can also work as:

• Associates of another dentist who’s in private practice
• Employees of a corporation or managed care organization
• Professors or clinical instructors at a dental school
• Researchers for universities, government organizations, or private companies
• Clinicians working with the World Health Organization and non-governmental organizations (NGOs) to train dentists in developing countries and provide low-cost services where needed
• Policy makers helping formulate public health law and regulations through universities, professional organizations, and government agencies
• Military officers treating service members
• Self-employed dentists usually work full time but have a great deal of flexibility to set their own hours. Many work some evenings and weekends to accommodate their patients’ schedules.

Like all health care professionals, dentists are at increased risk of exposure to contagious diseases, including HIV and hepatitis. Proper use of protective clothing and equipment reduces the risk of disease transmission.

Hover over any state to explore local income and job growth data.

According to the US Bureau of Labor Statistics, general dentists earn a median annual salary of $159,770. The lowest-paid 10 percent earned less than $67,660, and the highest-paid 10 percent earned more than $187,200.

Dentist salaries vary considerably by specialty. An orthodontist or oral surgeon will generally earn considerably more than someone practicing general dentistry. Earnings also increase with years in practice and hours worked.

Dentists should be in demand over the next few years. According to the BLS, employment of dentists is expected to grow by 18 percent between 2014 and 2024, which is a lot faster than the average for all occupations.

The growth of the elderly population is one factor driving the need for dentists. Today’s Baby Boomers are more likely than previous generations to keep their natural teeth into old age. Older people generally consume more dental services as their teeth experience age-related wear and tear.

In addition, the public is becoming more aware of the link between oral health and overall health, making them more likely to seek regular dental services.

Finally, a growing number of people have dental insurance, thanks to federal laws mandating payers to cover certain services. This should reduce the financial barriers to dental care for lower- and middle-income families and increase the demand for services.

Dentists can improve their job outlook by working in areas where dentists are in short supply or entering a high-demand specialty such as cosmetic dentistry.

Dentist job openings are often posted on the websites of private and corporate practices, universities, and government agencies.

High school students considering a career in dentistry should take a full college-preparatory curriculum, including as many advanced math and science classes as possible. Advanced Placement, International Baccalaureate, or dual-placement science classes are desirable. This is also a good time to explore health careers through employment, shadowing, or volunteering.

No specific college major is required for dental school, but students should complete the following prerequisites:

• Two semesters of biology with lab
• Two semesters of general chemistry with lab
• Two semesters of organic chemistry with lab
• Two semesters of physics with lab

• Additional prerequisites (check the programs you are applying to)

Admission to dental schools can be quite competitive. Schools prefer well-rounded candidates who maintain a high GPA while taking a challenging course load. Leadership, community service, and health-related work and research experience are also desirable. College students planning to apply to dental school should take the Dental Admission Test during junior year.

Most students enter dental school with a bachelor’s degree, though some schools accept promising applicants with 2-3 years of solid undergraduate achievement. The first two years of dental school are classroom-based and cover anatomy, physiology, microbiology, radiology, pharmacology, dental techniques, and practice management. Third- and fourth-year students rotate through clinics specializing in surgery, pediatric dentistry, restorative dentistry and more, where they practice their skills under supervision.

Be sure to graduate from a program accredited by the Commission on Dental Accreditation (CODA).

While a residency isn’t required for general dentistry, a growing number of students are choosing to pursue advanced training through one of the following programs:

• Advanced Education in General Dentistry (AEGD) is a one-year program emphasizing clinical care and practice management
• General Practice Residency (GPR) is an intensive 1- or 2-year program that prepares general dentists for hospital practice

All dental specialties require a residency after dental school. Residency typically lasts 1-3 years, but can span as long as six for oral and maxillofacial surgeons (who often earn a medical doctorate, or MD, in the process).

All dentists must be state-licensed in order to practice. Requirements vary by state, but usually include:

• Graduation from a CODA-accredited training program
• Passage of Parts I and II of the National Board Dental Examinations, a multiple-choice test covering biological science, anatomy, ethics, clinical knowledge, and patient management
• Passing performance on a practical examination covering clinical skills

Board exams are integrated into the dental school curriculum. Part I is taken after Year 2 and Part II and the clinical exam after Year 4.

Some states have additional requirements. For more information, contact your state board of dentistry.

For many people, the long road to becoming a dentist represents a pinnacle career achievement in itself. However, those seeking additional challenges often pursue opportunities in research, dental education, and public policy.

In order to get into dental school, you’ll first need to complete some undergraduate coursework. You can major in any subject so long as you fulfill your dental school prerequisites. These are very similar to medical school and vary a bit between dental programs. But almost every dental school wants to see at least a year each of the following:

• Biology with lab
• Chemistry with lab
• Organic chemistry with lab

• Physics with lab

Other common prereqs include biochemistry, anatomy, physiology, and English composition.

Students planning to apply to dental school should also take the Dental Admissions Test (DAT). This exam covers biology, general chemistry, and organic chemistry, among other subjects. Most students take it junior year after completing their prerequisite coursework.

In order to practice as a dentist, you’ll need to earn one of the following professional degrees. There are no real differences between them; different schools simply prefer different names:

• Doctor of Dental Surgery (DDS)
• Doctor of Dental Medicine (DDM)
• Doctor of Medical Dentistry (DMD)

Most dental programs are housed within four-year universities. Accreditation is very important in dentistry. You must attend a program accredited by the Commission on Dental Accreditation (CODA) in order to be licensed in most states. CODA currently accredits 66 DDS/DDM/DMD programs.

Dental school admissions are highly competitive. While some programs accept students with 2-3 years of undergraduate coursework, most enter dental school with a bachelor’s degree. Other factors considered are grades, DAT scores, difficulty of undergraduate coursework, leadership experience, and work and volunteer experience in healthcare

During years 1 and 2 of dental school, students take courses in:

During years 1 and 2, students also complete lab work, simulations, and early fieldwork in general dentistry.

Years 3 and 4 focus on clinical training. Students rotate through different specialties like surgery and restorative dentistry. They also gain experience treating different populations like children and older people. Clinical placements may be on campus or in the community.

After graduating from dental school, students are qualified to practice general dentistry. However, more and more dentists are pursuing post-graduate training through one of the following programs:

Dentists who complete a CODA-approved residency may pursue voluntary board certification. This is usually done near the end of residency or soon after graduation. Board-certified dentists are called diplomates.

Each specialty has a board that administers its certification process. The following boards are recognized by the American Dental Association:

• Dental public health
• Endodontics
• Oral and maxillofacial pathology
• Oral and maxillofacial radiology
• Oral and maxillofacial surgery
• Orthodontics
• Pediatric dentistry
• Periodontology
• Prosthodontics

It’s worth noting that many unrecognized specialty boards also offer certification (for example, the American Dental Board of Anesthesiology).
