Dental school takes 4 years. But that’s not all! The whole path to become a dentist takes 8-12+ years.

Let’s break it down step by step!
The Step-by-Step Path to Become a Dentist
1. College Years (4 Years)
Before dental school, you need to go to college. You will take classes like:
- Biology
- Chemistry
- Physics
You need good grades to get into dental school. You also need to take a big test called the DAT (Dental Admission Test) in your junior year.
2. Dental School Years (4 Years)
Dental school has two parts:
First 2 Years:
- Learn about teeth and the body
- Study in classes and labs
- Take tests about dental facts
Last 2 Years:
- Work with real patients
- Do more than 1,500 hours of hands-on work
- Learn how to fix teeth
During dental school, you take big tests called the National Board Dental Examinations.
3. Extra Training (1-6+ Years)
After dental school, you can:
- Start working as a general dentist
- Get more training to be a special dentist
If you want to be a special dentist, here’s how long it takes:
- Orthodontist (braces doctor): 3 more years
- Oral Surgeon (teeth surgeon): 4-6 more years
- Pediatric Dentist (kids’ dentist): 2-3 more years
This Table Shows How Long Each Step Takes
Step | Time | What You Do | Tests |
---|---|---|---|
College | 4 years | Biology, Chemistry, Physics | DAT |
Dental School | 4 years | Learn about teeth, work with patients | NBDE Part I/II |
General Dentist | 0-1 year | Optional extra training | State license exams |

Things That Can Make Dental School Take Longer
Sometimes, it might take more time to finish. Here’s why:
- Failed Tests: If you don’t pass a test, you might need to wait and take it again. This can add 6-12 months to your time.
- Gap Years: Some people take time off between college and dental school to:
- Get better grades
- Get more experience
- Save money
- Dual Degrees: If you want two degrees (like DDS/PhD), it takes 7-8 years instead of 4 years.
- Part-Time Programs: These are rare but can make school take longer.
- International Students: If you studied dentistry in another country, you might need to take a 2-3 year program to work in the US.
What You Learn in Dental School
