Overview of the Profession

Advances in dental research including genetic engineering, the discovery of links between oral and systemic diseases, the development of salivary diagnostics and the continued development of new materials and techniques make dentistry an exciting, challenging and rewarding profession. Today's dental practitioners are highly sophisticated health professionals who provide a wide range of oral health care.  Dentistry also offers individuals the opportunity to pursue an academic career, engaged in teaching and research, or to work independently in private practice. 

Practice Areas

  • Clinical Fields: There are 9 clinical fields in dentistry. Although most dentists are in general practice (80%) 20% choose to specialize in one particular area.
  • General Dentistry: General dentists diagnose, educate, perform surgery and rehabilitation to restore damaged or missing tooth structure and treat diseases of the bone and soft tissue in the mouth. Post-doctoral training is not required for general dentistry although general practice residencies and advanced education are available.
  • Dental Public Health: These practitioners are involved in developing policy and programs, such as health care reform that affect the community at large. Post-doctoral work in public health is required. There are 13 programs and 19 first-year residents in the United States. Visit the American Association of Public Health Dentistry Web site.
  • Endodontics: Endodontists diagnose and treat diseases specific to the dental nerves an matter inside the tooth. Postdoctoral education is required for this specialty – either a master’s or certificate program in endodontics. Visit the American Association of Endodontists Web site.
  • Oral and Maxillofacial Pathology: Oral pathologists study the causes, processes and effects of diseases with oral manifestations., Oral pathologists do not treat patients directly but rather provide the diagnostic and consultative biopsy services to dental practitioners and physicians in the treatment of patients. Post-doctoral education is required. 
  • Oral and Maxillofacial Surgery: This specialty concentrates on the treatment of defects of the neck, head, jaw and other aligned structures. Postdoctoral education is required either in the form of a degree or certificate program. The length of these specialty training programs is generally 4 years. Visit the American Association of Oral and Maxillofacial Surgeons Web site.
  • Orthodonticas and Dentofacial Orthopedics: Specialists in Orthondontics treat irregular development of teeth – including missing teeth, over/under bites, crowded teeth etc. Postdoctoral education is required for this specialty generally lasting 24-36 months. Visit the American Association of Orthodontists Web site.
  • Pediatric Dentistry: Pediatric dentistry concentrates on the dental population of children from birth to adolescence. Postdoctoral education is required for this specialty generally lasting 24-36 months. Visit the American Academy of Pediatric Dentistry Web site.
  • Periodontics: This specialty diagnoses and treats diseases of the gingival tissue (including the gums, oral mucous membranes and other surrounding tissue) and bone supporting the teeth. Postdoctoral education is required for this specialty generally lasting 36 months. Visit the American Academy of Periodontology Web site.

  • Salaried Employee or Associate: Most recent graduates begin their careers in salaried or associate positions in private practices, but most choose to move to practice ownership within several years.
  • Dental Research/Academic Dentistry: Dental researchers are those individuals engaged in scientific research related to oral health. Many researchers are found in academic settings and also engage in teaching in a dental school environment. Other faculty at dental schools are part-time, splitting their time between teaching and private clinical practice. Many researchers are faculty members at universities; others work in federal facilities such as the National Institute of Dental and Craniofacial Research (NIDCR), the National Institutes of Health (NIH), or in private industry. Postgraduate fellowships and opportunities are available in a variety of areas and sponsored by public and private organizations.
  • Service in the Federal Government: The federal government offers numerous opportunities for dental school graduates.  Dentists may enlist in the military to serve military personnel and their families.  Scholarships and loan repayment programs for dental students and graduates are also available.   
  • Salary and Lifestyle: The dentist's typical day is diverse and interesting. The careers and lifestyles of dentists are also flexible and dynamic. me. Salaries will vary by geographic location and specialty but  According to the Survey of Dental Practice by the Health Policy Institute of the ADA, the average net income for general dentists in private practice in 2022 was $218,220 and $335,920 for specialists. The U.S. Bureau of Labor Statistics estimates the average annual income for general dentists is $172,290. Additionally, the demand for new dentists is continuing to grow.  The U.S. Bureau of Labor Statistics estimates that there will be  26,700 new dentist job openings through the year 2024. 


A dental education requires a minimum of four years of dental school. At the conclusion of dental school individuals receive a doctoral degree (DDS or DMD dependent on school). Dental education itself includes a study of the basic health sciences, including anatomy, biochemistry, histology, microbiology, pathology, pharmacology and physiology, with emphasis on dental aspects. It also includes application of these health sciences to patient care. The final two years of dental school concentrate on clinical training. This training is designed to introduce students to the basic techniques involved in oral diagnosis, restorative dentistry, periodontics, oral surgery, orthodontics, pediatric dentistry, prosthodontics, endodontics and other types of treatment. During these two years there is also a didactic emphasis on practice management in dentistry. Third and fourth year dental students rotate through various clinics to treat their own patients under the supervision of clinical instructors.

Pre-Dental Requirements: To check specific requirements please refer to ADEA Official Guide to Dental Schools or search by individual schools. For information about how to fulfill these courses at Columbia, please see Premedical Curriculum


Many factors are considered by dental schools when deciding who to admit into their classes. Applicants are assessed based on their academic potential, personal readiness, and motivation for a career in dentistry. The steps in the application process are outlined below.

Timing of application : Admission at most dental schools is rolling which means that many schools have a large percentage of their class full by the end of December of each year. The message here is APPLY EARLY!

State of Residency: Virtually all public, state-supported dental schools show preference for admitting applicants who are legal residents of that state. You should understand that this practice is based on both economic and philosophical reasoning. First, education at those schools is funded primarily by the taxpayers of the state. Those taxpayers expect some priority in access to medical training. In addition, the state legislators feel an obligation to educate health professionals to serve the people of their state; experience as well as data where available show that individuals who attend dental school in their home state will likely eventually practice in that state.

Full-time undergraduate students are considered residents of the state in which their parents live. Applicants may claim residency in only one state, which means that, an applicant’s likelihood of acceptance may be influenced greatly by their state of residence. Detailed information on acceptance rates of in-state vs. out-of-state applicants for professional schools can be found in the ADEA Official Guide to Dental Schools.The time required to establish residency varies greatly, from 6 months to five years. Contact schools for further information about residency requirements.

Activities: Dental schools are looking for well-rounded individuals who demonstrate commitment, leadership, a disposition to serve others and a positive work ethic. They will also be looking for individuals who demonstrate an ability to interact with others, and cultural competency. Your extracurricular activities can help you demonstrate that you can manage a rigorous academic schedule while still having meaningful involvement on campus and in the community.

Experience with Dentistry: Volunteering or working with a dentist is a valuable experience that will help you to learn more about the field and to determine whether this is the correct career choice for you. It also demonstrates to admissions committees that you are committed to your goal and have thoroughly researched your interest.

Application Process

AADSAS : The Association of  American Dental Schools Application Service (AADSAS) is a centralized application sponsored by the American Dental Education Association. This is an online application that will enable you to apply to multiple dental schools. This is the first step in your application process to dental school.  It opens on June 1st. 

Secondary Application: Most dental schools will send applicants an additional application to be completed after receipt of the AADSAS. The form of this application will vary from school to school, but may include additional essays and an additional fee. 

Interviews : Most dental schools will invite those candidates under serious consideration to campus for an interview.

DAT : The Dental Admission Test is required by all dental schools and should be taken at least one year prior to expected matriculation in dental school. The test is administered on computer and therefore applicants have flexibility regarding scheduling. The examination requires that students have taken the prerequisites in Biology, Chemistry and Organic Chemistry.

ADEA: The America Dental Education Association is the premier association serving the allied, predoctoral, and postdoctoral dental education community.
