Becoming a dentist takes a minimum of eight years after high school: four years of undergraduate education followed by four years of dental school. If you pursue a specialty like orthodontics or oral surgery, add two to six more years of residency training. The path is demanding and expensive, but the career offers strong earning potential, with general dentists earning a median salary of $172,790 per year.
Undergraduate Prerequisites
You don’t need a specific major to get into dental school. Biology, chemistry, and health sciences are popular choices, but admissions committees care more about your prerequisite coursework and GPA than the name of your degree. According to the American Dental Education Association, dental schools traditionally require:
- 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
Some schools will accept one semester of biochemistry in place of the second semester of organic chemistry. Beyond these core sciences, many programs also expect coursework in English, psychology, or statistics, though requirements vary by school. Check each program’s prerequisites individually before planning your course schedule.
The DAT and Building Your Application
The Dental Admission Test (DAT) is a standardized exam covering natural sciences, perceptual ability, reading comprehension, and quantitative reasoning. Most students take it during the spring or summer before their senior year of college, giving them time to include scores in their application. A competitive score varies by school, but strong performance in the sciences section carries particular weight.
Clinical shadowing is a critical part of your application. Many dental schools set minimum requirements. Indiana University School of Dentistry, for example, requires at least 100 hours of shadowing across three different dental settings. Even if a school doesn’t list a specific number, having substantial shadowing experience signals genuine interest and helps you write a more compelling personal statement. Try to shadow in a mix of environments: a general practice, a specialty office, and a community health clinic give you the broadest perspective.
You’ll apply through ADEA AADSAS, the centralized application service for dental schools. The application typically opens in mid-May, with the first submission date in early June. The cycle closes the following February. After you submit your application, pay fees, and send official transcripts, processing takes four to six weeks. Applying early in the cycle is widely considered an advantage, since many schools review applications on a rolling basis.
What Happens in Dental School
Dental school is a four-year program that awards either a DDS (Doctor of Dental Surgery) or DMD (Doctor of Medicine in Dentistry) degree. These two degrees are clinically identical. Both use the same curriculum requirements set by accreditation standards. The university simply chooses which title to award. A dentist with a DDS has the same education and qualifications as one with a DMD.
The first two years focus heavily on biological sciences. You’ll study the structure and function of the body, the diseases that affect it, and the pharmacology behind treatment. Outside of lecture halls, you practice dental procedures on simulation models of the mouth and teeth. This is where you learn the mechanics of fillings, crowns, extractions, and other procedures before touching a real patient.
Years three and four shift mostly to clinical work. You’ll treat patients in the school’s dental clinic under faculty supervision, handling everything from routine cleanings and restorations to more complex procedures. Some practice management instruction is woven in during these later years, covering topics like running an office, managing staff, and understanding insurance systems. By graduation, you’ll have logged hundreds of hours of direct patient care.
Licensing Requirements
Graduating from dental school doesn’t automatically make you a licensed dentist. You need to pass a series of exams. The Integrated National Board Dental Examination (INBDE) is a two-day test administered by the Joint Commission on National Dental Examinations. It evaluates whether you have the clinical knowledge to safely practice entry-level dentistry. Most students take it during dental school.
Beyond the national written exam, every state requires a clinical licensing exam where you demonstrate hands-on skills. The specific exam accepted varies by state. Some states also have their own jurisprudence exams covering local dental laws and regulations. Once you hold a license, you’ll need to complete continuing education credits throughout your career to maintain it.
Specializing After Dental School
General dentists can practice immediately after licensing, but if you want to specialize, you’ll need additional residency training. Program lengths vary significantly by specialty and institution:
- Orthodontics: 2 to 5 years, with most programs running about 3 years
- Oral and maxillofacial surgery: 4 to 6 years, the longest of any dental specialty. Some programs include medical school and award a dual dental/medical degree.
- Endodontics (root canals): 2 to 3 years for most programs
- Periodontics (gum disease): 3 to 4 years in a typical program
Other recognized specialties include pediatric dentistry, prosthodontics (replacement teeth like dentures and implants), oral pathology, and dental public health. You apply to residency programs through ADEA PASS, a centralized matching service similar to the one used in medical residencies.
Cost of Dental Education
Dental school is one of the more expensive professional degrees. The most recent data from the American Dental Education Association puts the average educational debt for the Class of 2025 at $297,800. That figure includes both undergraduate and dental school borrowing for graduates who carried debt.
Tuition at public dental schools is lower than at private institutions, especially if you attend in your home state. But even public school graduates often carry significant loans. Income-driven repayment plans, loan forgiveness programs for dentists working in underserved areas, and military service scholarships are common strategies for managing this debt. Some dentists also work as associates in established practices for several years after graduation, building income before taking on the additional financial commitment of opening their own office.
Job Outlook and Career Paths
The Bureau of Labor Statistics projects 4% job growth for general dentists through 2034, roughly in line with the average for all occupations. Demand stays relatively steady because oral health care is a consistent need regardless of economic conditions, and an aging population increasingly seeks dental services to maintain their teeth longer.
Career paths after licensing are more varied than most people realize. You can join an existing group practice, work as a solo practitioner, become a partner in a dental office, or work for a corporate dental chain. Community health centers, hospitals, the military, and academic institutions all employ dentists. Some dentists split their time between clinical practice and teaching at dental schools. Others focus entirely on research or public health policy. The flexibility to shape your practice style and schedule is one of the profession’s biggest draws.
