Becoming an oral radiologist — formally, an oral and maxillofacial radiologist — takes three milestones: a dental degree, a CODA-accredited residency of at least 24 months (accredited programs averaged 28.7 months in 2025-26), and a state dental license.
Board certification is the layer every other recognized specialty has and this one doesn't yet: no recognized certifying board exists as of October 2026, though an application is pending.
Here is each step and the small market at the end of it.
The short answer: dental degree, residency, state license
Oral and maxillofacial radiology is the dental specialty concerned with the production and interpretation of images and data produced by all modalities of radiant energy, used to diagnose and manage diseases, disorders and conditions of the oral and maxillofacial region.
The Bureau of Labor Statistics' Occupational Outlook Handbook puts the work plainly: diagnosing diseases in the head and neck through the use of imaging technologies.
It is one of the 12 dental specialties the ADA's National Commission on Recognition of Dental Specialties and Certifying Boards currently recognizes.
Because it is a dental specialty, the schooling and the credentials underneath it are dentistry's own.
Three milestones, plus the optional credential this specialty doesn't have yet:
- Dental school. A dental degree — the "required dental education" in the National Commission's definitions — is the first requirement in its definitions of specialist status.
- The specialty residency. A CODA-accredited oral and maxillofacial radiology program of at least 24 months full-time or its equivalent; accredited programs averaged 28.7 months in 2025-26.
- A state dental license. The National Commission calls a specialist "educationally qualified" once dental school and the advanced residency are complete and a state dental board has granted a license to practice dentistry.
- Optional credentials, where they exist. Board certification is the voluntary credential the specialties with a recognized board offer — but this specialty has no recognized certifying board to offer one yet.
What you hold at the end is a dental degree, a residency credential and a license — and, uniquely among the recognized specialties right now, no recognized board certification to add to them.

One size check before you commit: the ADA's Health Policy Institute counted 225 professionally active dentists holding an oral and maxillofacial radiology certificate or degree in 2025, and 17 people graduated from the specialty's residency programs that year.
Every stage below — the residency pool, the board question, the job search — is shaped by how small this field is.
The residency: at least 24 months, with hospital radiology inside
The residency is the specialty's defining stage.
CODA — the Commission on Dental Accreditation — requires an advanced oral and maxillofacial radiology program to run a minimum of 24 months full-time or its equivalent.
Read that as the accreditation floor, not a typical length: the average accredited program ran 28.7 months in the 2025-26 survey year.
One requirement inside those months shapes where you train.
CODA requires oral and maxillofacial radiology residents to complete a rotation in an active, hospital-based radiology department or other similar facility of at least three months, or its part-time equivalent.
The medical-radiology exposure is written into the specialty's accreditation standard, not left to each program's preference.
The pipeline through these programs is small at every stage.
Per the CODA/ADA Health Policy Institute's 2025-26 Survey of Advanced Dental Education, there were 8 accredited programs, 24 residents entering their first year, 58 residents enrolled in total, and 17 graduates in 2025.
Those programs counted 270 applications — a number to read carefully, because HPI tallies an applicant once for every program applied to, so 270 is applications, not applicants, and no acceptance rate can be computed from it.
Cost runs in both directions.
First-year tuition and fees averaged $19,992 across the five programs that charged them, while first-year stipends averaged $35,392 across the programs that paid one.
Both averages exclude the programs charging or paying nothing, and individual programs vary widely — confirm current terms with each program directly.
How applications, accreditation and advanced education fit together across all of dentistry's specialties is a bigger question than this page: the dental residency overview explains that machinery once for every specialty.
For the programs themselves, the oral and maxillofacial radiology program directory lists the individual accredited residencies.
Board certification: voluntary — and no recognized board yet
This is where the specialty diverges from most of dentistry.
The National Commission recognizes 12 dental specialties but currently lists 11 national specialty certifying boards, and it accepts no more than one certifying board per specialty — oral and maxillofacial radiology has none among the 11.
The specialty is recognized; a board to certify its specialists is not.
In the specialties that do have a board, certification is a voluntary layer.
The Commission's own wording: "Board certification is a voluntary process that demonstrates a commitment to lifelong learning and continued professional development."
The Commission defines a "board eligible" specialist as one who has completed the required dental education and the advanced residency and is eligible to take the board certification examination — a rung that, for this specialty, currently has no examination to land on.
That may change.
ADA News reported on September 30, 2026 that the American Certifying Board of Oral and Maxillofacial Radiology had applied to the National Commission to be recognized as the specialty's national certifying board, with public comments due by 5 p.m. CST on November 13, 2026.
Until a recognition decision lands, nobody can hold certification from a National Commission-recognized board in this specialty — so treat any "board-certified oral radiologist" claim you encounter skeptically, and check the Commission's recognized certifying boards list for the current status before relying on one.
No recognized certifying board as of October 2026
First jobs: a small market and a state-license wrinkle
The market you enter is sized to the field.
The ADA's Health Policy Institute counted 225 professionally active dentists holding an oral and maxillofacial radiology certificate or degree in 2025 — up from 190 in 2022, with 204 in 2023 and 213 in 2024 in between.
HPI's supply table counts a dentist under every specialty credential they hold, so that is a count of credential-holders, not of full-time specialists.
And the pipeline feeds it slowly: 17 residency graduates in 2025.
The role you'd be hired into follows the specialty's definition — producing and interpreting the images other dentists use to diagnose and manage disease.
No source we found counts hiring volume for the title, so treat the search practically: the career guide covers the settings the specialty works in, and a market this small rewards watching specialist and imaging-heavy dentist listings and the specialty's professional networks rather than any one channel alone.
Licensure is the step with a state line in it.
State rules differ: some states issue separate specialty licenses or certificates and others do not — Kansas recognizes specialist certificates in branches including oral and maxillofacial radiology, separate from the general dental license, and Michigan may issue specialty licenses in branches of dentistry.
Where the requirement exists, it can reach how you present your work: in South Carolina, a dentist must obtain a special license from the Board of Dentistry (S.C. Code § 40-15-220) before announcing or holding out to the public as limiting their practice to, being a specialist in, or giving special attention to any special area of dentistry.
Because the answer changes at the state line, confirm the rules with your state dental board before you practice or advertise as a specialist.
