No β the medical degree is optional.
CODA's accreditation standard for oral and maxillofacial surgery sets a four-year, full-time training floor for every program and does not require an M.D.; in 2025-26, 51 of the institutions behind the country's 103 accredited OMS programs offered an option to pursue one.
This page sets out what each path involves in training and credentials, what first-year residency cost and paid across all programs, and where the published data on pay and hospital privileges stops.
Short answer
No β the M.D. is optional, and "4-year vs 6-year" is shorthand rather than two official categories.
CODA's accreditation standard for oral and maxillofacial surgery sets a single four-year, full-time floor for every OMS program and does not define a "six-year track" at all.
What the labels describe is whether a program also offers the medical degree alongside specialty training.
In 2025-26, 103 accredited OMS programs were operating, and 51 dental schools and institutions offered accredited programs with an option to pursue an M.D.
BLS describes OMS programs as typically taking 4 to 6 years, and says they may result in a joint M.D. degree.
Either path trains you for the same recognized specialty, which the National Commission on Recognition of Dental Specialties and Certifying Boards defines as including diagnosis and surgical and adjunctive treatment of diseases, injuries and defects of the hard and soft tissues of the oral and maxillofacial region.
Either way, the decision attaches to specific programs: each program either offers an M.D. option or it doesn't, so the practical choice is between programs.
For how applications and matching work, and what the four-year floor covers, see oral surgery residency; this page stays on the path decision.

The 4-year certificate path
The 4-year path is an accredited OMS program completed without the medical degree, finishing with the specialty credential the program itself confers.
Its floors are CODA's, and every OMS program meets them regardless of degree: a minimum of four years of full-time study, with at least 120 weeks devoted to clinical OMS inside that time.
The block that looks least like dental school is anesthesia.
CODA requires at least 32 weeks on anesthesia and medical services, including at least 20 weeks on the anesthesia service functioning as an anesthesia resident.
Graduating residents must also be trained to competence in delivering general anesthesia and deep sedation to patients aged 8 and older.
The didactic side is covered within the program too.
CODA's standard allows some of the required biomedical science instruction to be met "through the completion of the requirements for the M.D./D.O. or any other advanced degrees" β the requirement stands whether or not a resident collects a second degree; the M.D. is one allowed way to meet it.
The pipeline's scale in 2025-26: 103 programs enrolled 285 first-year residents, and 257 residents graduated in 2025.
That graduate count covers both structures.
The 6-year MD path
The MD path is specialty training at an institution that also offers the medical degree.
The CODA/ADA HPI survey lists 51 dental schools and institutions offering accredited OMS programs with an option to pursue an M.D. in 2025-26, out of 103 programs operating that year.
Read the wording precisely: the count pairs institutions against programs, and "option to pursue" is the survey's phrase β it does not say the M.D. is mandatory at those institutions.
What CODA's standard itself says about integration is narrow: coursework taken for the M.D./D.O. may satisfy some of a program's biomedical science instruction requirements.
That is the mechanism the standard names.
It sets no separate duration for integrated programs β the only length CODA fixes for OMS is the same four-year floor every program meets.
The "six years" label traces to BLS's description of the specialty: "Oral and maxillofacial surgery programs typically take 4 to 6 years and may result in candidates earning a joint Medical Doctor (M.D.) degree."
No separate length for MD-integrated programs appears in this research: CODA's standard sets only the four-year floor, and BLS's description stops at the 4-to-6 range.
What is measured is the average across all accredited programs: 53.1 months in 2025-26 β one figure covering programs with and without an M.D. option, so it doesn't show how long any single program runs.
Does the MD change pay or scope?
On pay, the published data cannot answer the question.
BLS reports a single median for the whole specialty β $352,220 per year for oral and maxillofacial surgeons in May 2025 β with no split between MD and non-MD graduates.
That one figure is the federal data for this specialty, so it is the number to quote, with its limits; no source in this research gives the degree a pay premium.
On scope, the two paths don't produce two specialties.
The NCRDSCB definition is one definition, and CODA's clinical floors β the 120 clinical weeks, the 32-week anesthesia and medicine block, competence in general anesthesia and deep sedation for patients aged 8 and up β are the same standards for every accredited program, degree or no degree.
The workforce is counted as one group too.
ADA HPI tallied 7,482 professionally active dentists holding an OMS certificate or degree in 2025 β one count, no degree-path split.
Hospital privileges are the other place the degree question comes up, and they are where this page's sources run out: neither CODA's training standard nor the federal wage data addresses how hospitals credential OMS graduates.
If operating privileges are central to your plans, ask the programs on your list directly β and ask the credentialing offices at the hospitals you'd want to operate in.
Where this page's data stops
How to decide
You don't pick a path in the abstract β you apply to specific programs, and each program either offers an M.D. option or it doesn't.
That makes the decision concrete: compare the programs on your list, not the two categories.
For where the specialty's match stands this cycle, see OMS match competitiveness.
Time is the clearest difference to price out.
The floor is four years, BLS describes typical programs at 4 to 6 years, and the 2025-26 average was 53.1 months.
Every month past the floor is training time rather than specialist earning time, whatever degree is attached to it.
Money during residency varies more than the category labels suggest.
In 2025-26, 90 of 103 OMS programs paid first-year residents an average stipend of $66,596, while 28 of 103 charged first-year tuition and fees averaging $40,651.
Both averages count only the programs that paid or charged, so ask each program on your list where it actually sits.
- Is the M.D. required, optional, or not offered here?
- What credential does the program confer, and how long does it run?
- How are the anesthesia and hospital medicine rotations structured?
- What do first-year residents earn or pay β stipend, tuition, or neither?
- Where do you want to practice β office-based, hospital-based, or both?
The answers, plus where you want to operate, are the decision.
The published data in this article can frame those questions; it can't rank the two paths for you.
