So you’re wondering how long does it take to be a dentist? The short answer: roughly 8-12 years after high school. But that’s just the headline. The real journey involves undergrad, dental school, licensing exams, and potentially specialty training. Let’s break down exactly what you’re getting into, step by step, so you know what to expect before committing to this rewarding career path.

Undergrad Requirements First
Before you even touch a dental school application, you need a bachelor’s degree. This typically takes 4 years, though some students finish in 3 with AP credits or summer courses. During undergrad, you’ll need to complete specific prerequisites: biology, chemistry, organic chemistry, biochemistry, physics, and sometimes microbiology. These aren’t electives—dental schools require them.
Here’s the thing: you don’t necessarily need a degree in biology or pre-dental studies. You can major in whatever interests you, as long as you complete those science courses. Many students take 4 years because they’re building their GPA, volunteer hours, and shadowing experience alongside coursework. The stronger your application, the better your chances at competitive dental schools.
Dental School: The Core Years
This is where the real dental training happens, and it takes 4 years. The first two years are typically classroom and lab-based—you’re learning anatomy, pharmacology, dental materials, and clinical techniques on phantom heads before touching real patients. The last two years flip the script: you’re working with actual patients under supervision, managing cases, and building clinical skills.
Dental school is intense. You’re looking at classes, labs, clinical rotations, and studying for board exams simultaneously. Some students describe it as medical school’s equally demanding cousin. The curriculum covers general dentistry, and you’ll get exposure to different specialties so you can figure out your career direction. By graduation, you should be competent to practice general dentistry independently.
Licensing Exams and Boards
After dental school graduation, you’re not quite done. You need to pass licensing exams to legally practice. In the US, this means passing the National Board Dental Examination (NBDE) Part I and Part II, plus a state-specific clinical exam. Most students take these exams while still in dental school or immediately after graduation.
The NBDE Part I covers basic sciences and typically happens during your second year of dental school. Part II focuses on clinical sciences and patient care. Then there’s the Integrated National Board Dental Examination (INBDE), which some states now require instead of separate exams. These exams aren’t quick—you’ll spend weeks or months studying and preparing. Most students pass on their first attempt, but if you don’t, you’re adding more time to your timeline.
Specialty Programs Add Time
Want to be an orthodontist, oral surgeon, or endodontist? Add 2-4 more years. Specialty residencies vary in length. Orthodontics typically takes 2-3 years, while oral and maxillofacial surgery can take 4-6 years depending on the program and whether you pursue additional training. Periodontics, prosthodontics, and pediatric dentistry each have their own timelines, usually 2-3 years.
Getting into a competitive specialty program requires excellent grades, board exam scores, and sometimes research experience. If specialization is your goal, you’re looking at 12-16 total years from high school to becoming a specialist. That’s a significant commitment, but specialists often earn more and have different career flexibility than general dentists.

Total Timeline Breakdown
Let’s do the math on the standard path:
- High school to bachelor’s degree: 4 years
- Dental school (DDS or DMD): 4 years
- Licensing exams: Overlap with school, 3-6 months of dedicated study
- Starting practice: Immediately after passing boards
Total for general dentist: 8 years minimum, typically 8-9 years. Add specialty training (2-4 years) if you’re going that route. Like any major goal, the timeline depends on your specific path and choices.
Accelerated Program Options
Some dental schools offer 3-year DDS/DMD programs instead of the standard 4. These are compressed and intense—you’re in school year-round with minimal breaks. They’re competitive to get into and definitely not for everyone. You’ll need a strong undergrad record and dental school prerequisites completed before enrollment. A few programs even allow you to start dental school with just 2-3 years of undergrad completed if you finish remaining requirements during dental school.
The advantage? You save a year or two. The disadvantage? You’re working harder and faster with less time to absorb material, build clinical skills, or explore specialties. Most students choose the traditional 4-year path because it allows better work-life balance and more thorough learning.
Real-World Factors That Matter
Your actual timeline might differ based on several factors. If you need to retake the NBDE or state exams, you’re adding months. If you want to pursue a specialty but don’t get accepted on your first try, you might work as a general dentist for a year or two before reapplying. Some people take gap years between undergrad and dental school to work, volunteer, or boost their application.
Financial constraints can also affect timing. Some students work part-time during undergrad to manage costs, which might extend their degree timeline. Others take out loans and finish faster. According to the American Dental Association, the average dental school graduate carries significant student debt, so many new dentists spend their early career managing loans while building their practice.
Geographic location matters too. If you want to practice in a specific state, you might need to take that state’s clinical board exam, which has different schedules and requirements. International dental graduates have an even longer path because they need additional exams and certifications to practice in the US.
Getting Started Today
If you’re serious about becoming a dentist, start now. Take challenging science courses in high school. Shadow a dentist to confirm it’s the right career. Volunteer at dental clinics or community health centers. Build strong grades—dental schools look at your entire academic record, not just science courses.

During undergrad, maintain a high GPA (3.5+), complete all prerequisites, take the Dental Admission Test (DAT), and get clinical experience. The DAT is similar to the MCAT for medical school—it’s competitive and requires serious preparation. Most students study 3-4 months for it. Start thinking about dental school applications in your junior year so you’re ready to submit early in your senior year. Early applications have better acceptance rates.
Research dental schools thoroughly. Some are 4-year programs, others offer 3-year options. Some emphasize research, others focus on clinical practice. Find programs that match your goals and learning style. The American Dental Association’s website lists accredited programs and provides detailed information about dental education requirements.
Frequently Asked Questions
Can you become a dentist in less than 8 years?
Technically, yes, with an accelerated 3-year dental program and no gap years. However, this is rare and extremely demanding. Most dentists complete the journey in 8-9 years following the traditional path. Specialty training adds additional years on top.
Do you need a specific undergraduate major?
No. You can major in anything as long as you complete the required science prerequisites. Some students major in biology or chemistry, others in engineering, business, or humanities. Dental schools care about your prerequisite courses and overall GPA, not your major.
What’s the difference between DDS and DMD?
DDS (Doctor of Dental Surgery) and DMD (Doctor of Dental Medicine) are equivalent degrees from different schools. The curriculum and training are essentially the same. It’s just terminology—some schools use DDS, others use DMD. Both qualify you to practice general dentistry and take the same licensing exams.
How much does dental school cost?
Dental school is expensive. Private schools run $60,000-$80,000 per year, while public schools average $30,000-$40,000 annually. Four years adds up to $120,000-$320,000 depending on the school. Most graduates use federal loans, private loans, or scholarships to cover costs. The Association of American Medical Colleges provides information about dental education financing.
Is becoming a dentist worth the time investment?
That’s personal, but consider this: dentists earn a median salary around $160,000-$180,000 annually, with experienced practitioners earning significantly more. You’re building a career with strong job security, flexibility to specialize or work independently, and the satisfaction of helping people. The 8-12 year investment pays off professionally and financially for most dentists.
Can you practice dentistry while in dental school?
No, not independently. You’ll work on patients under close supervision during your clinical years, but you can’t legally practice on your own until you graduate and pass licensing exams. Some dental schools allow students to work as dental assistants or hygienists before or during school to gain experience and earn income.
