In the United States, becoming a dentist usually takes about 7–8 years of education after high school: typically 3–4 years of undergraduate study followed by a four-year DDS or DMD program. You must also meet your state’s licensing requirements before practicing; application timing, prerequisite coursework, gap years, and optional specialty training can extend the path. The ADA describes this common education sequence.
The 7–8 year estimate is a typical route, not a guarantee or a licensing deadline. Some schools have different admission rules, and the amount of undergraduate study needed varies. A DDS and a DMD meet the same educational standards; the degree name depends on the school.

The typical U.S. timeline
- Undergraduate preparation: about 3–4 years. Complete the courses and other prerequisites required by the schools you plan to apply to. A bachelor’s degree is common, but requirements differ, so confirm each school’s current admissions policy.
- Dental school: typically 4 years. Accredited DDS and DMD programs combine classroom learning, laboratory work, and supervised clinical care.
- State licensure: timing varies. Graduation alone does not authorize practice. Each state or territory sets its licensing process, including examination and application requirements.
- Specialty training: optional and additional. A dentist who pursues a recognized specialty completes postgraduate education; the length depends on the specialty and program.
If you are already completing the required undergraduate courses, the dental-school portion is typically four years. If you are starting after high school, the common education estimate is about seven to eight years before adding any time needed for admissions, licensure processing, or specialty training.
What can make the timeline longer?
The four-year dental-school program is only one part of the calendar. These factors can add time to an individual route:
- Prerequisites may take longer if you change majors, repeat courses, or complete additional undergraduate study.
- Dental-school applications follow an annual cycle. Applying after a deadline, strengthening an application, or reapplying can add a cycle. Check the current ADEA application timeline and each school’s dates.
- DAT preparation or a retake may shift the date you submit an application. The ADA maintains the current DAT requirements, scoring information, and candidate guide.
- A leave of absence, part-time enrollment, or personal circumstances can change a student’s completion date.
- Specialty residency or advanced training comes after the DDS/DMD and is not included in the general-dentist estimate.
DAT and the dental-school application
The DAT is an admissions test, not a dental license exam. The ADA says U.S. dental schools require applicants to take it; schools also evaluate their own prerequisites and application materials. Confirm the current test format, scoring scale, submission deadlines, and accepted coursework directly with the ADA and each school.
Most U.S. dental schools use ADEA AADSAS, although some applicants use a different service. ADEA publishes cycle dates, and individual schools set their own deadlines and supplemental requirements. Plan backward from the intended start date rather than assuming an application or review period is identical every year.
What happens during dental school?
A typical DDS or DMD program takes four years. Students build biomedical and clinical knowledge, develop practical skills, and provide supervised patient care. Program structures vary, so review the curriculum and accreditation status of each school rather than relying on a single universal year-by-year schedule.
The ADA states that DDS and DMD degrees satisfy the same educational requirements and are accepted as equivalent for general dentistry licensure. The letters are different; the education standard is the same.
Licensure: graduation is not the final step
Dentists must be licensed in the jurisdiction where they practice. The ADA says state boards set the requirements; candidates generally need an accredited DDS or DMD, a written examination, and a clinical assessment or another state-accepted pathway. All U.S. licensing jurisdictions require the Integrated National Board Dental Examination (INBDE); the INBDE replaced the former NBDE Part I and Part II. Clinical assessment options and other details vary by state, so check the ADA licensure overview and your state dental board.
Older pages may refer to the NBDE or quote a fixed number of days or months for licensure. Those are not a reliable guide to today’s process: verify current exams, accepted assessment routes, documents, and processing times with the licensing board where you intend to work.
Optional specialty training
A DDS or DMD prepares a graduate for general dentistry after licensure. Becoming a specialist requires additional postgraduate education, and training length varies by specialty and program. If you are considering a specialty, check the accredited program’s current requirements and duration through the Commission on Dental Accreditation program directory.
Plan finances and course credentials separately
The time estimate does not predict the cost of dental school. Tuition, fees, living expenses, aid, and debt vary by school and student; use each school’s current cost-of-attendance and financial-aid pages when planning.
CareersForge’s Foundations in Dentistry course is an introductory learning resource. Its course-completion certificate documents completion of that course; it is not a DDS or DMD, an accredited dental-school qualification, an ADA exam result, or a state license, and it does not authorize someone to practice dentistry.

Frequently asked questions
How many years does it take to become a dentist in the U.S.?
A common route is about seven to eight years of education after high school: three to four years of undergraduate study and four years in dental school. Add any admissions delays, state licensing steps, or specialty training that applies to your route.
Does dental school itself take four years?
Most traditional U.S. DDS and DMD programs take four years. Check the specific program for its schedule and admission requirements.
Do I need a bachelor’s degree before dental school?
A bachelor’s degree is common, but the required undergraduate coursework and degree policy vary by dental school. Follow the current rules of each program you are applying to.
Is the DAT the same as the INBDE?
No. The DAT is used in dental-school admissions. The INBDE is a written examination required for U.S. dental licensure.
Can I practice as soon as I graduate?
No. You must meet the licensing requirements in the state or territory where you plan to practice. Contact that jurisdiction’s dental board for current steps and timing.
How much longer does a dental specialty take?
Specialty training is additional to the DDS or DMD, and its duration depends on the specialty and accredited program. Confirm the current program length in the CODA directory.
