Becoming a dentist takes about eight years after high school: four years of undergraduate education followed by four years of dental school. If you specialize, add one to four more years on top of that. The path is demanding but structured, and knowing each step upfront helps you plan your time, finances, and coursework from day one.
Undergraduate Coursework That Matters
You’ll need a bachelor’s degree before applying to dental school. There’s no required major, so you can study anything from biology to business, but you must complete a set of prerequisite science courses. These typically include two semesters each of biology, general chemistry, organic chemistry, and physics, all with lab components. Some dental schools will accept one semester of biochemistry in place of the second semester of organic chemistry.
Beyond the hard sciences, many dental schools strongly encourage coursework in the arts and social sciences. Classes in psychology, communication, or ethics can strengthen your application and prepare you for the patient interaction side of the profession. Admissions committees want to see that you can think beyond the lab bench.
Grades matter significantly. Students who enrolled in dental school in 2024 had an average overall GPA of 3.67 and a science GPA of 3.59. About 32% of enrollees had an overall GPA of 3.75 or higher. You don’t need a perfect transcript, but consistently strong performance in science courses is expected.
The Dental Admission Test
The DAT is a standardized exam required by virtually every dental school in the United States. It covers biology, general chemistry, organic chemistry, reading comprehension, quantitative reasoning, and a perceptual ability section that tests your spatial reasoning, a skill that matters when you’re working inside a mouth with mirrors and small instruments.
Scores are reported on a scale where 400 puts you near the 54th percentile for most sections, meaning you’ve outscored roughly half of test takers. A score of 450 places you around the 82nd to 85th percentile, which is competitive for most programs. These percentile ranks are based on a normative sample of more than 30,000 DAT attempts over a recent two-year period. Most students spend two to three months studying, often using dedicated prep courses or self-study materials.
Dental School: Four Years of Training
Dental school awards either a Doctor of Dental Surgery (DDS) or a Doctor of Medicine in Dentistry (DMD). These are the same degree with the same curriculum requirements. The title simply depends on which university you attend. Both prepare you identically for licensure and practice.
The first two years focus heavily on classroom and lab-based learning. You’ll study anatomy, pharmacology, pathology, and dental materials while practicing techniques in simulated settings. At many programs, you begin working on mannequin-like models two to four afternoons per week during your first year, building foundational skills like preparing a tooth for a filling or taking impressions.
By the summer of your second year, you transition into direct patient care. Students typically spend around 32 hours per week treating real patients under faculty supervision, performing cleanings, restorations, extractions, and other procedures. The third and fourth years are almost entirely clinical. You’ll rotate through on-campus dental clinics and community-based sites, often completing two seven-week rotations at outside clinics serving underserved populations. This is where the profession starts to feel real, and where you develop the speed and judgment that classroom work alone can’t teach.
Some accelerated programs combine the bachelor’s degree and dental doctorate into six or seven years total, shaving a year or two off the traditional timeline. These are competitive but worth exploring if you’re certain about dentistry early on.
Licensing Requirements
After graduating from dental school, you must pass the Integrated National Board Dental Examination (INBDE) to practice. This is a two-day exam designed to assess whether you have the clinical knowledge and judgment to safely practice entry-level dentistry. Every U.S. state and territory accepts it as fulfilling all or part of the written examination requirement for licensure.
Most states also require a separate clinical licensing exam, which varies by region. Some states use their own clinical tests while others accept results from regional testing agencies. You’ll need to check the specific dental board in whatever state you plan to practice, since requirements differ. Once licensed, you’ll also need to complete continuing education credits throughout your career to maintain that license.
Specialization Options
General dentistry doesn’t require residency beyond dental school, though many new graduates choose a one-year general practice residency to build confidence and experience. If you want to specialize, you’ll need additional training. There are currently 12 recognized dental specialties, including orthodontics, pediatric dentistry, periodontics (gum treatment), endodontics (root canals), prosthodontics (crowns, bridges, and dentures), and oral and maxillofacial surgery.
Most specialty residencies last one to two years. Oral and maxillofacial surgery is the exception, requiring four to six years of additional training, sometimes including a medical degree. Specialty residencies are competitive, and your dental school grades, board scores, and clinical evaluations all factor into admission.
Cost of Dental Education
Dental school is a major financial commitment. For the 2024-25 academic year, the average four-year tuition and fees for in-state residents is $252,563. When you add living expenses, that total climbs to about $295,285. Out-of-state students pay more: an average of $323,852 in tuition alone, or roughly $366,574 including total costs. These figures don’t include undergraduate debt, which many students carry into dental school.
Most dental students finance their education through federal loans. Loan repayment options include income-driven repayment plans, and some dentists reduce their debt through programs that offer loan forgiveness in exchange for practicing in underserved areas. The investment is substantial, but earning potential helps offset it over time.
Career Outlook and Earnings
General dentists earned a median annual salary of $172,790 as of May 2024, according to the Bureau of Labor Statistics. Specialists typically earn more, with orthodontists and oral surgeons often exceeding that figure significantly. The field is projected to grow 4% from 2024 to 2034, roughly in line with the average for all occupations, driven by an aging population that’s keeping its natural teeth longer and increasing demand for dental care.
Most dentists work in private practice, either owning their own office or joining an existing one. Corporate dental groups have also expanded rapidly, offering salaried positions that appeal to new graduates who want steady income without the overhead of running a business. Other paths include academia, public health, research, and military dentistry.
