The Timeline: 10 to 14 Years After High School

Becoming an oral surgeon takes 10 to 14 years of education and training after you finish high school. The exact length depends on whether you pursue additional specializations and how quickly you complete each stage. Most oral surgeons finish dental school in four years, then complete a surgical residency that runs three to four years, with some choosing to add fellowship training afterward.

The path is longer than becoming a general dentist (which takes six to eight years total) because oral surgery requires both a dental degree and specialized surgical training. Unlike some professions where you can start working partway through, you cannot practice as an oral surgeon until you have completed your residency and passed your licensing exams.

Key Takeaways

  • Dental school takes four years and is required before any surgical training can begin.
  • A surgical residency in oral and maxillofacial surgery takes three to four years after dental school.
  • Some oral surgeons add a one- to two-year fellowship for additional subspecialty training in areas like orthognathic surgery or implant dentistry.
  • You must pass the Dental Admission Test (DAT) before dental school and obtain state licensure after dental school before starting your residency.
  • The total time from high school to independent practice ranges from 10 to 14 years depending on whether you pursue fellowship training.

Dental School: Four Years

Dental school is the first major milestone and takes four years of full-time study. During these four years, you learn general dentistry, anatomy, pharmacology, and the fundamentals of oral surgery. You spend time in classrooms and laboratories, then move into clinical rotations where you work with patients under supervision.

Before you can enter dental school, you must take the Dental Admission Test (DAT), which tests your knowledge of biology, chemistry, organic chemistry, and reading comprehension. Most students take the DAT during their junior or senior year of undergraduate study. Dental schools also require a bachelor's degree, though it does not have to be in a science field—you just need to complete prerequisite courses in biology, chemistry, organic chemistry, and physics.

Dental school is competitive. Schools look at your DAT score, your undergraduate GPA, volunteer experience in dental settings, and letters of recommendation. Many students shadow dentists or work as dental assistants before explore to strengthen their candidacy.

Oral Surgery Residency: Three to Four Years

After dental school, you enter a surgical residency in oral and maxillofacial surgery, which lasts three to four years depending on the program. During residency, you train in a hospital or surgical center under the supervision of experienced oral surgeons. You perform extractions, place implants, repair jaw fractures, remove tumors, and handle complex surgical cases that general dentists do not manage.

Residency is competitive. Programs rank candidates based on their dental school grades, performance on the National Board Dental Examination (NBDE), letters of recommendation from dental school faculty, and interview performance. You must also have passed the NBDE Part I and Part II exams and obtained your state dental license before starting residency.

During residency, you are paid a salary (typically between $40,000 and $70,000 per year, though this varies by program and location), so unlike dental school, you are earning income while training. However, the hours are long—many residents work 50 to 60 hours per week, including on-call shifts.

Licensing and Board Certification

After you complete your residency, you must pass the Oral and Maxillofacial Surgery Board Examination to become board-certified. This is a written and oral exam administered by the American Board of Oral and Maxillofacial Surgeons. Board certification is not legally required to practice, but most employers and patients expect it, and many insurance plans reimburse at higher rates for board-certified surgeons.

You also need a state dental license and a state surgical license in the state where you plan to practice. Requirements vary by state, but most require you to pass the NBDE exams and show proof of your residency training. Some states require additional exams or paperwork.

Optional Fellowship Training: One to Two Years

Some oral surgeons pursue a fellowship after residency to specialize further in areas like orthognathic surgery (jaw realignment), reconstructive surgery, or dental implant surgery. A fellowship typically lasts one to two years and is completed at a university hospital or specialized surgical center.

Fellowship training is optional and not required to practice as an oral surgeon. However, it can make you more competitive for certain jobs, especially in academic medicine or specialized surgical centers. If you pursue a fellowship, add one to two years to your total timeline.

Why the Timeline Is Longer Than Other Dental Specialties

Oral surgery requires more training than other dental specialties because it involves surgery in the operating room, general anesthesia, and complex medical cases. A periodontist (who specializes in gum disease) or an orthodontist (who straightens teeth) typically completes a two- to three-year specialty program after dental school. Oral surgeons need longer because they must master surgical technique, manage surgical complications, and handle medical emergencies that can arise during procedures.

The surgical residency also includes rotations in hospital departments like anesthesia, emergency medicine, and internal medicine so that you can safely manage patients with complex medical histories and handle complications that may occur during surgery.

Timeline Variations and What Affects Your Speed

The 10 to 14-year timeline assumes you complete each stage without delays. Some factors can shorten or lengthen your path. If you finish your undergraduate prerequisites early and take the DAT in your junior year, you might enter dental school a year earlier. Conversely, if you do not get into dental school on your first attempt, you may reapply the following year, adding 12 months to your timeline.

Residency length varies slightly by program. Some programs are three years; others are four. A few programs offer combined degrees (like a DDS/MD) that take longer but train you as both a dentist and a physician. If you pursue a fellowship, add another one to two years. If you pursue additional board certification in a subspecialty (like the American Board of Oral and Maxillofacial Pathology), that adds more time.

Your undergraduate timeline also matters. If you need to take prerequisite courses before starting your degree, or if you take a gap year to gain experience before dental school, your total time increases. Most students take at least one gap year between high school and dental school to work, volunteer, or strengthen their process.

Frequently Asked Questions

Can I start practicing as an oral surgeon before I finish my residency?

No. You cannot practice oral surgery independently until you have completed your residency and passed your board examination. During residency, you work under the supervision of attending surgeons. Once you finish residency and pass your boards, you can open your own practice or join an established surgical center.

Do I have to do a fellowship after my residency?

No. A fellowship is optional. Most oral surgeons complete their residency and begin independent practice without additional fellowship training. A fellowship is useful if you want to subspecialize or work in academic medicine, but it is not required to become a practicing oral surgeon.

What if I don't get into dental school on my first try?

Many students reapply after strengthening their candidacy. You can retake the DAT, improve your GPA through additional coursework, gain more dental experience, or get stronger letters of recommendation. Reapplying typically adds one year to your timeline, though some students take longer to prepare for a second attempt.

Is the timeline the same in every state?

The dental school and residency timeline is the same nationwide. However, state licensing requirements vary. Some states require additional exams or have different continuing education requirements. You should check with the dental board in the state where you plan to practice for specific requirements.

How much does it cost to become an oral surgeon?

Dental school tuition ranges widely depending on whether you attend a public or private school and what state you live in. Public dental schools typically cost $20,000 to $40,000 per year; private schools often cost $50,000 to $80,000 per year. Over four years, total dental school debt can range from $80,000 to $320,000 or more. Residency is paid, so you earn income during those three to four years, which helps offset some of your dental school debt.
