How Many Years Does It Take to Become a Dentist?
If you are considering a career in dentistry, one of the first questions you will probably ask is: how many years does it take to become a dentist?
In the United States, becoming a dentist typically takes about 8 years of full-time education after high school. This generally includes four years of undergraduate college followed by four years of dental school. However, the total timeline can be longer depending on the dental school, the student's academic path, and whether the dentist chooses to specialize.
Dentistry is a highly educated healthcare profession, and becoming a licensed dentist requires completing dental education, passing licensing examinations, and meeting the requirements of the state where you plan to practice.

For the traditional pathway, the timeline looks approximately like this:
StepTypical LengthHigh school4 yearsBachelor's degree4 yearsDental school4 yearsTotal after high schoolAbout 8 yearsTotal including high schoolAbout 12 years
The most common route is to earn a bachelor's degree and then attend dental school for four years. Dental schools award either a Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DMD). Despite the different names, DDS and DMD degrees are equivalent professional degrees for practicing dentistry.
Step 1: Complete an Undergraduate Degree
The first major step toward becoming a dentist is attending college.
Most students complete a four-year bachelor's degree before entering dental school. Common majors include biology, chemistry, biochemistry, and other sciences, although dental schools generally do not require students to major in a particular subject as long as they complete the required prerequisite courses.
Dental school applicants typically need coursework in subjects such as biology, general chemistry, organic chemistry, and physics. Requirements vary by dental school.
Students also generally need to build a competitive dental school application through strong academic performance, dental or healthcare experience, extracurricular activities, and other qualifications.
Step 2: Apply to Dental School
Dental school admission is competitive, so students often begin preparing their applications well before graduation from college.
Applicants commonly take the Dental Admission Test (DAT), although requirements can vary by school and program.
Dental schools evaluate applicants using multiple factors, including academic performance, prerequisite coursework, standardized testing where required, personal statements, recommendations, interviews, and relevant experiences.
Because admission can take additional time if a student needs to strengthen an application or reapply, the actual path to becoming a dentist can sometimes exceed eight years after high school.
Step 3: Complete Four Years of Dental School
Once admitted, students generally spend four years in dental school.
The first portion of dental school typically emphasizes foundational biomedical sciences and the scientific basis of oral health. Students study subjects such as anatomy, physiology, microbiology, pathology, pharmacology, and dental sciences.
As students progress, the curriculum increasingly focuses on clinical dentistry.
Dental students learn and practice procedures involving areas such as:
Preventive dentistry
Restorative dentistry
Periodontics
Prosthodontics
Oral surgery
Endodontics
Pediatric dentistry
Radiology
Diagnosis and treatment planning
Clinical education allows students to treat patients under faculty supervision before they graduate.
DDS vs. DMD: Is One Faster?
No.
A Doctor of Dental Surgery (DDS) and Doctor of Dental Medicine (DMD) are both professional dental degrees. The difference is primarily the name of the degree rather than the level of education.
Both generally require approximately four years of dental school after completing the necessary undergraduate education.
Therefore, whether a student attends a DDS or DMD program does not normally change the basic eight-year post-high-school timeline.
How Long Does It Take to Become a Licensed Dentist?
Finishing dental school is not necessarily the final step.
After earning a DDS or DMD, graduates must satisfy the licensing requirements of the state in which they intend to practice. Requirements can include examinations and other state-specific requirements.
Once the graduate fulfills the applicable requirements and receives a dental license, they can practice as a general dentist within the scope permitted by that license.
Because licensing requirements vary by state, students should check the requirements of the state where they intend to practice.
How Long Does It Take to Become a Specialist Dentist?
Becoming a general dentist usually takes about eight years of education after high school.
Becoming a dental specialist takes longer.
After dental school, dentists who want to specialize generally complete an additional postgraduate residency. The length depends on the specialty.
Examples include:
Dental SpecialtyTypical Additional TrainingOrthodonticsAbout 2–3 yearsPediatric dentistryAbout 2 yearsPeriodonticsAbout 3 yearsProsthodonticsAbout 3 yearsEndodonticsAbout 2–3 yearsOral and maxillofacial surgeryGenerally 4–6 yearsOral and maxillofacial pathologyAbout 3 years
Exact residency lengths vary by program.
For example, someone who completes four years of college, four years of dental school, and a three-year specialty residency could spend approximately 11 years in higher education after high school.
Can You Become a Dentist in Less Than Eight Years?
There are accelerated educational pathways that can shorten the traditional timeline, including some combined undergraduate and dental programs.
However, these programs are not the standard route and can have highly competitive admissions requirements.
Students should also distinguish between becoming a dental professional and becoming a licensed dentist. Dental assistants and dental hygienists, for example, can enter the dental field with substantially less education, but they are not dentists and cannot perform the full scope of services reserved for licensed dentists.
Is Becoming a Dentist Worth the Time?
Dentistry requires a substantial investment of time and education, but it also provides a professional career centered on healthcare, patient relationships, and oral health.
Dentists can work in private practices, group practices, hospitals, community health centers, academic institutions, and other healthcare settings. Some eventually own their own practices or pursue careers in education, research, public health, or dental administration.
The education and licensing requirements are demanding because dentists perform procedures that directly affect patients' health and well-being.
Dentist Education Timeline: The Bottom Line
For most students in the United States, becoming a general dentist takes approximately eight years after high school:
4 years of college + 4 years of dental school = approximately 8 years.
After dental school, the graduate must complete the applicable licensing requirements before practicing independently.
Students who pursue a dental specialty should expect additional postgraduate education, often adding two to six or more years depending on the specialty.
For someone interested in dentistry, the best time to start planning is during high school or college. Understanding prerequisite courses, dental school admissions requirements, the DAT, clinical experience, and state licensing requirements early can make the path to becoming a dentist much easier to navigate.
