The Path to Becoming a Dentist: General Timeline
The short answer is that it can take between six and eight years to become a dentist. However, the exact timeline can vary based on a few different factors. Let’s take a look at the most common ones.
Specialization
If you choose to specialize in a certain type of dental treatment, such as oral surgery or periodontology, you’ll need to complete additional training and educational programs before offering those services. Some of the top specializations include:
-
Endodontics: Treat diseases and injuries related to the soft tissues inside the tooth
-
Orthodontics: Correct irregularities of the teeth and jaws
-
Pediatric Dentistry: Treat dental conditions in younger patients
-
Oral and Maxillofacial Pathology: Diagnose and treat diseases that affect the mouth and jaw
-
Periodontics: Treat conditions that affect the gums and bone surrounding the teeth
-
Prosthodontics: Restore or replace teeth using crowns, implants, and cosmetic solutions
If you choose not to specialize, you’ll follow a general dentistry path, providing preventive care and performing procedures such as fillings, extractions, and crowns.
Most specializations require a residency of one to two years, while advanced fields like oral surgery may take four to six years.
Academic Program
There are two main routes to become a dentist:
-
Traditional Route: Four years of undergraduate study, followed by four years of dental school (total of eight years).
-
Combined Program: A six-year BS/DDS or BS/DMD program that merges undergraduate and dental training within one institution.
Undergraduate Studies
Your undergraduate major can influence your dental school readiness. Students majoring in biology, chemistry, or pre-med typically meet the prerequisites for dental school earlier.
If you’re also considering optometry or comparing the two paths, check out our DAT vs OAT Difficulty Guide to see how the exams differ.
Before applying, you must earn a bachelor’s degree. In combined programs, students complete both degrees simultaneously, saving up to two years.
Dental Program
After undergrad, you’ll apply to dental school — and the first step is taking the Dental Admission Test (DAT).

If you pass and are admitted, you’ll complete four years of advanced coursework and clinical training, earning one of two degrees:
-
DDS: Doctor of Dental Surgery
-
DMD: Doctor of Medicine in Dentistry
Both degrees are equivalent and meet the same licensing standards.
Common courses include:
General Biology • General and Organic Chemistry • Oral Microbiology • Dental Anatomy • Dental Radiology
Many programs also include internships and residencies for hands-on experience.
Admission to Dental School
Admission is highly competitive. If you aren’t accepted on your first try, it can delay your timeline — so preparation matters.
Start with a solid understanding of the DAT’s new 3-digit scoring system using our DAT Percentiles – How to Interpret Your Score and Improve Your Chances.
We offer up-to-date study materials, tutoring sessions, and live DAT classes designed by Dr. Jim Romano to help students master every section.
In addition to strong DAT scores, you’ll need a competitive GPA and strong recommendation letters from professors or employers who can vouch for your dedication.
Licensing Exam
After dental school, you’ll take the National Board Dental Exam, which includes two parts and a total of 500 questions. Passing this exam allows you to obtain a license to practice in your state.
If you’ve specialized, you’ll also complete board exams specific to your field.
