If you’re considering a dental career in the United States, one of the first questions is: how many years will it take to become a dentist?
The short answer: For general dentistry, about 8 years — and up to 14 years if you specialize. But the full timeline includes specific steps: undergrad, dental school, licensing, and possibly residency.
Let’s walk through it.
1. Undergraduate Degree: 4 Years
Most dental schools require a full bachelor’s degree, though technically 90 college credits can qualify.
Students usually major in:
- Biology
- Chemistry
- Health sciences
- Pre-med or pre-dent
Core science prerequisites are required no matter the major.
2. Dental Admission Test (DAT)
Before applying to dental school, students take the DAT — a standardized test that assesses:
- Natural sciences
- Perceptual ability
- Reading comprehension
- Quantitative reasoning
✅ Preparation often takes 3–6 months and overlaps with undergrad.
3. Dental School: 4 Years
Once accepted, students complete a 4-year dental program (either a D.D.S. or D.M.D. — both are equivalent).
Dental school includes:
- 2 years of science-heavy classroom learning
- 2 years of clinical experience with real patients
4. Licensure Exams: A Few Months
To legally practice, graduates must:
- Pass the INBDE (national dental board exam)
- Pass a clinical board exam (varies by state).
- Licensing requirements are regulated at the state level across the U.S., so the timeline may vary slightly depending on where you plan to practice.
- Meet any state-specific requirements (e.g., jurisprudence exam, background check)
This process usually happens right after dental school and takes a few months.
5. Optional: Dental Residency (1–6 Years)
Required only for specialization (not general practice).
Common specialties:
- Orthodontics
- Oral Surgery
- Pediatric Dentistry
- Endodontics
Residencies range from 1 to 6 years, depending on the specialty.
