An oral and maxillofacial surgeon (OMS) is a dentist who completed a surgical residency of at least four years — typically four to six — focused on the mouth, jaws, and face; a general dentist is the broad-scope primary provider whose typical duties, per BLS, run from filling cavities to removing damaged teeth and making models for dentures.
The split runs on referral: oral surgery is one of dentistry's referral-driven specialties, with general dentists sending the surgical cases — impacted teeth, jaw surgery, facial trauma — to an oral surgeon.
The short answer
A general dentist is trained broadly and is most people's main dentist; an oral and maxillofacial surgeon is a specialist who added the longest residency minimum in dental specialty education.
Tooth removal is a typical general-dentist duty — BLS lists it — so the difference is the training depth behind complex surgical cases, and how the patient arrives.
Oral surgery is a referral-driven specialty: general dentists treat their own patients and send the surgical work — impacted teeth, jaw surgery, trauma — out to an OMS, rather than that demand arriving walk-in.
What each one does
A general dentist runs comprehensive primary oral care — BLS's typical-duties list has it removing decay and filling cavities, repairing or removing damaged teeth, and making models and measurements for dental appliances such as dentures — and treats surgery of the mouth and jaw as one item on a much longer list.
An oral surgeon does one thing in depth: surgery of the mouth, jaws, and face — dentoalveolar surgery (including impacted wisdom teeth and complex extractions), dental implant placement, corrective jaw (orthognathic) surgery, facial trauma, and oral pathology.
| Comparison | General dentist | Oral surgeon |
|---|---|---|
| Tooth removal | A typical general-dentist duty (BLS) | Dentoalveolar surgery, including impacted and complex extractions |
| Training beyond dental school | None required (BLS) | At least four years — the CODA minimum; BLS says programs typically take 4 to 6 years |
| Board certification | Not applicable to this scope | American Board of Oral and Maxillofacial Surgery (ABOMS) — voluntary |
| How the patient arrives | Existing patient of record | On referral — oral surgery is one of the GP-referral-driven specialties |
What the OMS residency adds
Both start the same way: dental school for a DDS or DMD — most programs require a bachelor's degree first — then licensure.
A general dentist can begin practicing there (BLS: no additional training required).
An oral surgeon continues into an oral and maxillofacial surgery residency — at least four years per CODA's accreditation minimum, typically four to six per BLS, with 51 institutions offering programs with an MD option in 2025-26 — built around dentoalveolar and orthognathic surgery, facial trauma, and oral pathology, with at least 32 weeks on anesthesia and medical services.
After residency, oral surgeons can pursue certification from the American Board of Oral and Maxillofacial Surgery (ABOMS) — voluntary, not a license, but the certifying board the National Commission recognizes for this specialty.
It's the longest residency minimum in dental specialty education; see how to become an oral surgeon for the full sequence, or the residency's CODA-set four-year minimum for what the accrediting standard actually requires.
Where the referral line sits
There's no fixed rule: licensure requirements vary by state, and the line also moves with each dentist's training and comfort.
What's structural is the training difference.
Tooth removal is on BLS's list of typical general-dentist duties, and general dentists need no additional training after dental school (BLS).
The surgical end of that line — dentoalveolar surgery, complex implant work, orthognathic surgery, facial trauma, pathology — is what the OMS residency exists to train.
The procedures that OMS training exists for — impacted and complex extractions, complex implant work, jaw surgery, facial trauma — are the ones that arrive by referral: oral surgery runs on referrals from general dentists rather than on direct-to-consumer demand.
The referral relationship
Oral surgery is referral-driven — a general dentist sends the case, and the OMS's practice depends on that relationship rather than on direct-to-consumer demand the way orthodontics or pediatric dentistry often is.
For the specialty comparison on the orthodontic side of that line — wisdom teeth and jaw surgery versus braces — see orthodontist vs. oral surgeon.
The division of labor holds after surgery too: the surgical phase is the OMS's side of the split, while restorative work — the fillings, crowns, and dentures on BLS's general-dentist duties list, or the final crown on an implant, which belongs to restorative dentistry or a prosthodontist — sits outside the surgical training an OMS completes.
Pay: tracked under separate codes
The U.S. Bureau of Labor Statistics tracks general dentists on their own occupational code: SOC 29-1021, Dentists, General, with a national median of $170,950 a year (OEWS, May 2025).
See the dentist salary guide for the full breakdown.
Oral and maxillofacial surgeons have their own code too: SOC 29-1022, with a national median of $352,220 a year — the highest of the dental specialties BLS tracks separately (OEWS, May 2025).
BLS's wage estimates exclude the self-employed and owners and partners in unincorporated firms, so they understate pay for practice owners.
