Becoming a dentist requires a bachelor's degree (any major, but with specific prerequisite courses), four years of dental school earning a DDS or DMD degree, and passing national and state licensing exams. The full timeline is 8+ years after high school. Average dental school debt exceeds $290,000, but the median dentist salary of $170,910 makes the math work — if you plan your finances carefully.
Dentistry is one of those careers where the lifestyle looks incredible from the outside. High salary, business ownership potential, respected professional status, and the ability to set your own hours once you own a practice. From the inside, the picture is more complicated — and the financial reality of getting there is something most pre-dental students dramatically underestimate.
The question isn't whether dentistry is a good career. It's whether dentistry is a good career for you, given the 8+ years of training, the $200,000-$400,000 in educational debt, and the physical demands of spending decades hunched over patients' mouths. Those tradeoffs are worth it for some people and devastating for others.
What Dentists Actually Do
General dentists — which is what most dental school graduates become initially — perform examinations, diagnose oral diseases, create treatment plans, and provide preventive and restorative care. A typical day includes cleanings, fillings, crowns, extractions, and root canals, mixed with patient consultations and business management tasks.
Roughly 80% of dentists work in general practice. The remaining 20% specialize in areas like:
Orthodontics — braces and alignment. The highest-paying dental specialty, with median earnings well above $200,000.
Oral and maxillofacial surgery — surgical procedures on the jaw, face, and mouth. Requires 4-6 years of additional residency training after dental school.
Endodontics — root canals and treating diseases of dental pulp. Two additional years of residency.
Pediatric dentistry — treating children. Two additional years of residency.
Periodontics — treating gum disease. Three additional years of residency.
What nobody mentions in career guides: dentistry is physically demanding. You're working in a small space (someone's mouth) with precision instruments while maintaining awkward postures for hours. Back and neck problems are extremely common among dentists after 15-20 years. Hand tremors, even minor ones, can end a dental career.
If you're considering dentistry, shadow a practicing dentist for at least 40-60 hours before committing to the pre-dental track. Not 4 hours on a Tuesday afternoon — real, sustained exposure across different types of appointments. You need to see the root canal on a screaming 5-year-old, the impacted wisdom tooth extraction, and the end-of-day paperwork. Most people who drop out of pre-dental do so because they romanticized the career without seeing the daily reality.
Education Requirements
Undergraduate Prerequisites
You can major in anything, but dental schools require specific prerequisite courses:
- Biology with lab (2 semesters)
- General chemistry with lab (2 semesters)
- Organic chemistry with lab (2 semesters)
- Physics with lab (1-2 semesters)
- Biochemistry (1 semester, required by most schools)
- English composition (1-2 semesters)
Many pre-dental students major in biology or chemistry because these majors naturally cover most prerequisites. But dental schools don't prefer science majors. A student with a 3.7 GPA in English who aced their science prerequisites is just as competitive as a 3.5 biology major.
Your science GPA matters more than your overall GPA. Dental schools calculate it separately, and a 3.3 science GPA will hold you back even if your overall GPA is 3.8. For guidance on choosing the right undergraduate path, check our guide to choosing a college.
Dental Admission Test (DAT)
The DAT is a computerized exam covering natural sciences (biology, general chemistry, organic chemistry), perceptual ability (spatial reasoning — unique to dentistry), reading comprehension, and quantitative reasoning.
The exam is scored on a scale of 1-30. The national average is around 19-20. Competitive applicants typically score 20 or above. Top dental schools (UCSF, UPenn, Michigan) expect scores of 22+.
Most students study for the DAT for 3-4 months. DAT Bootcamp and DAT Destroyer are the most popular study resources. The exam costs $570 and can be taken year-round at Prometric testing centers.
Dental School (4 Years)
Dental school leads to either a DDS (Doctor of Dental Surgery) or DMD (Doctor of Medicine in Dentistry). The degrees are functionally identical — the name difference is purely historical.
The first two years are primarily classroom and lab work: anatomy, physiology, pharmacology, dental materials, and technique courses on simulation models. The second two years are clinical, where you treat patients under faculty supervision.
Dental school is expensive. The American Dental Education Association reports that average educational debt for dental school graduates was $293,900 for the Class of 2023. Private dental schools cost significantly more than public ones.
Dental school acceptance rates average around 55% nationally, but individual school rates vary enormously. Some schools accept 10% of applicants; others accept 70%+. Apply to 10-15 schools across selectivity tiers. The AADSAS application (dental school's equivalent of the Common App) streamlines the process, but each school charges a separate secondary application fee of $50-$100.
Step-by-Step Path
Step 1: Complete undergraduate prerequisites with strong science grades. Target a 3.5+ science GPA. Below 3.3, your chances drop significantly unless your DAT scores are exceptional.
Step 2: Accumulate dental shadowing hours. Most dental schools require or strongly prefer 100+ hours of shadowing. Start sophomore year so you have time to build hours across multiple practice types (general, pediatric, oral surgery).
Step 3: Take the DAT. Most students take it in the spring or summer before they apply (typically junior year). Score 20+ for a competitive application; 22+ for top-tier schools.
Step 4: Apply through AADSAS. Applications open in June, and applying early (June-August) significantly improves your chances. The process includes your academic record, DAT scores, personal statement, letters of recommendation, and descriptions of dental experiences.
Step 5: Complete dental school (4 years). Focus on building strong clinical skills during your third and fourth years. Start thinking about whether you want to specialize or enter general practice.
Step 6: Pass licensing exams. The National Board Dental Examinations (NBDE Part I and II, or the newer Integrated National Board Dental Examination — INBDE) plus a regional clinical licensing exam are required before you can practice.
Step 7: Decide between associateship and practice ownership. Most new graduates work as associates in established practices for 2-5 years before buying or starting their own practice. Associateship typically pays $120,000-$160,000, while practice owners earn more but take on business risk.
Salary and Job Outlook
The median annual wage for dentists was $170,910 in May 2023.1 The lowest 10% earned less than $79,270, while the top 10% earned more than $239,200+.
These figures include both associates and practice owners. Practice owners who run efficient offices in good locations can earn $250,000-$400,000, but they're also responsible for overhead, staff salaries, equipment costs, and practice loans.
Specialists earn substantially more. Orthodontists and oral surgeons routinely earn $300,000-$500,000, but they invested an additional 2-6 years of residency training to get there.
The BLS projects 4% growth in dentist employment from 2023 to 2033, roughly average for all occupations.1 The stable growth reflects steady demand — people always need dental care — combined with a controlled supply of new graduates (dental school capacity doesn't expand quickly).
What Nobody Tells You
The debt-to-income ratio takes years to resolve. With $293,900 in average dental school debt and starting associate salaries of $120,000-$160,000, your monthly loan payments will be $2,000-$3,000 for 10-20 years. You won't feel "rich" for the first 5-7 years despite the high salary. Many dentists in their 30s have a lower net worth than teachers because of their debt burden.
Practice ownership is a business, not just dentistry. Buying or starting a practice means becoming an employer, accountant, marketer, and HR department. Practices cost $500,000-$1,000,000+ to purchase. The business side overwhelms many dentists who just wanted to do clinical work.
Patient management is harder than clinical work. You'll spend significant energy managing anxious patients, explaining treatment costs, handling insurance disputes, and dealing with patients who don't follow care instructions. Communication skills matter as much as clinical skills.
The physical toll is cumulative. Musculoskeletal disorders affect a large proportion of dentists over their careers. Loupes (magnification glasses) and ergonomic positioning help, but decades of precision work in small spaces takes a toll. Many dentists reduce their clinical hours after age 55.
Corporate dentistry is changing the economics. Dental service organizations (DSOs) are buying up private practices and hiring new graduates as employees. This means more job security but less autonomy and often lower long-term earnings than ownership. The solo-practitioner model is shrinking.
Students weighing dentistry against other healthcare paths should explore whether the overall cost of college education justifies the investment for their specific situation.
Is This Career Right for You?
Dentistry is right for you if you enjoy precision manual work, want a healthcare career without the unpredictability of emergency medicine, and are comfortable with the business side of running a practice. The combination of clinical skill and entrepreneurship is rare — dentistry rewards both.
It's not right for you if you're primarily motivated by the salary (the debt makes the first decade harder than people expect), if you struggle with repetitive tasks (you'll do hundreds of fillings), or if the thought of being $300,000 in debt at age 26 keeps you up at night.
The best predictor of whether you'll enjoy dentistry? Whether you enjoyed your shadowing hours. Not tolerated them. Enjoyed them. If you watched a crown preparation and thought "I want to learn to do that," you're probably on the right track.
FAQ
Can I get into dental school with a low GPA?
A science GPA below 3.0 makes admission very unlikely at US dental schools. Between 3.0-3.3, you'll need exceptional DAT scores (22+) and strong non-academic factors. Some students complete post-baccalaureate programs to raise their GPA before applying. A few international dental schools accept lower GPAs, but their graduates face additional licensing hurdles in the US.
How much does dental school cost?
Annual tuition ranges from $35,000-$50,000 at public dental schools (in-state) to $60,000-$90,000 at private schools. Total cost of attendance including living expenses typically runs $300,000-$450,000 over four years. Financial aid consists primarily of federal loans.
Is the DAT harder than the MCAT?
They test different things. The DAT includes a unique perceptual ability section that tests spatial reasoning, while the MCAT includes a social sciences section. Most students find the MCAT more content-heavy, but the DAT's perceptual ability section is uniquely challenging. The DAT is shorter (about 4.5 hours vs. 7.5 for the MCAT).
Can I specialize after dental school?
Yes, but specialty residencies are competitive. Orthodontics and oral surgery are the most competitive, with acceptance rates around 10-15% for orthodontics programs. Less competitive specialties include public health dentistry and dental anesthesiology. Specialty training adds 2-6 years and often comes with a stipend rather than a salary.
How do I pay for dental school?
Federal Direct Unsubsidized Loans and Grad PLUS Loans cover most costs. Some students receive scholarships, but full-tuition scholarships in dental school are rare. Military scholarship programs (HPSP) pay full tuition plus a stipend in exchange for 4 years of active duty service after graduation. Income-driven repayment plans cap monthly payments at a percentage of your discretionary income after graduation.
