Pick orthodontics if you want tooth movement and bite correction delivered over long treatment horizons, without a surgical residency; pick oral and maxillofacial surgery if you want operative work with anesthesia training and can carry a longer program.
The floors say it plainly: orthodontics residency runs at least 24 months, oral surgery at least four years.
BLS medians run $289,140 for orthodontists and $352,220 for oral and maxillofacial surgeons (May 2025).
Here is the full comparison.
Orthodontist vs. oral surgeon: the short answer
Both are recognized dental specialties, and the body that recognizes them draws the line by what each treats.
The National Commission on Recognition of Dental Specialties and Certifying Boards (NCRDSCB) defines orthodontics and dentofacial orthopedics as covering the diagnosis, prevention, interception and correction of malocclusion, plus neuromuscular and skeletal abnormalities of the developing or mature orofacial structures.
Oral and maxillofacial surgery it defines as the diagnosis and surgical and adjunctive treatment of diseases, injuries and defects of the hard and soft tissues of the oral and maxillofacial region β the mouth, jaws and face.
Everything else in this comparison follows from that split.
Orthodontics has the shorter training floor: at least 24 months and 3,700 scheduled hours.
Oral and maxillofacial surgery (OMS) has the longer one: at least four years of full-time study, with required time on an anesthesia service.
The daily work divides between planned, visit-by-visit tooth and bite correction and surgical treatment across a whole region.
Even the federal pay data splits into two direct wage series rather than one shared line.
So the honest answer to "which is better for me" runs through three questions: whether you want surgery at the center of your work, how many extra residency years you can carry, and which patient relationship suits you β an orthodontist's scheduled visits across months or years of treatment, or an oral surgeon's procedure-centered care.
The deep dives live in the role guides β the orthodontist career guide and the oral surgeon career guide β and this page stays on the comparison itself: training first, then the work, then what the pay numbers do and don't settle.
If your real question is how an orthodontist divides cases with general dentists, that is a different match-up: orthodontist vs. general dentist.
Training: 24 months vs. four years at the floor
Both residencies sit after dental school and are accredited by the Commission on Dental Accreditation (CODA), which sets a minimum length for each.
For orthodontics and dentofacial orthopedics: at least 24 months and 3,700 scheduled hours β the orthodontics floor is written in scheduled hours, where the OMS floor is written in years and clinical weeks.
For OMS: at least four years of full-time study, with at least 120 weeks devoted to clinical oral and maxillofacial surgery.
The Bureau of Labor Statistics describes the wider pattern: dental specialty training is usually a 2- to 4-year accredited residency, and OMS programs typically take 4 to 6 years and may lead to a joint M.D. degree.
The M.D. sits in optional territory β in 2025-26, 51 dental schools or institutions offered accredited OMS programs with an option to pursue an M.D. degree, out of 103 OMS programs operating that year, per the CODA/ADA Health Policy Institute survey.
That is the survey's own wording for an option, not a requirement.
Actual programs run longer than the floors.
Across 2025-26, accredited orthodontics programs averaged 31.2 months and accredited OMS programs averaged 53.1 months β close to two extra years of training on the oral surgery side.
Anesthesia is the sharpest divide between the two standards.
CODA requires OMS residents to spend at least 32 weeks on anesthesia and medical services, including at least 20 weeks on the anesthesia service functioning as an anesthesia resident, and graduating OMS residents must be trained to competence in delivering general anesthesia or deep sedation to patients aged 8 and older.
The orthodontics standard's requirement weight sits elsewhere β in the 3,700 scheduled hours that build the diagnosis, prevention, interception and correction work the specialty definition names.
Side by side, the two pipelines look like this:
| Training | Orthodontics | Oral and maxillofacial surgery |
|---|---|---|
| CODA minimum | 24 months + 3,700 scheduled hours | 4 years, full-time (at least 120 weeks clinical OMS) |
| Average length, 2025-26 | 31.2 months | 53.1 months |
| Accredited programs | 69 | 103 |
| First-year residents | 431 | 285 |
| Total enrolled | 1,180 | 1,307 |
| Graduates in 2025 | 414 | 257 |
| Avg. first-year tuition and fees | $55,640 (57 of 69 programs charging) | $40,651 (28 of 103 charging) |
| Avg. first-year stipend | $33,390 (31 programs paying) | $66,596 (90 paying) |
Two caveats on the money rows.
The survey's averages count only the programs that charge tuition or pay a stipend β programs reporting $0 are excluded β and the columns run in opposite directions: most orthodontics programs charge first-year tuition (57 of 69) while far fewer pay a stipend (31), and OMS runs the other way, with 90 of 103 programs paying a first-year stipend against 28 charging tuition.
What the table cannot tell you is how hard each residency is to enter: these are program and enrollment counts, not applicant pools, so treat any acceptance percentage quoted elsewhere as unsourced.
Daily work: tooth movement over time vs. surgical sessions
An orthodontist's clinical work is the correction of malocclusion and of the neuromuscular and skeletal abnormalities the specialty definition names β planned treatment carried across a course of care rather than delivered in a single operative session.
The definition's own reach, from the developing to the mature orofacial structures, is why orthodontists treat both growing patients and adults.
An oral surgeon's clinical work is surgery and adjunctive treatment across the hard and soft tissues of the oral and maxillofacial region.
The residency builds anesthesia in as a core skill: graduating OMS residents must be trained to competence in delivering general anesthesia or deep sedation to patients aged 8 and older, so sedation planning is part of the job the training prepares you for.
The structural difference is the shape of a case.
Orthodontic care is planned correction delivered over a course of treatment; oral surgery is delivered in discrete operative sessions, each with its own preparation, anesthesia and recovery considerations.
Practices vary on both sides, but the specialty definitions mark where each career's center of gravity sits.
For scale, the workforces are differently sized.
ADA HPI counted 10,844 professionally active dentists holding an orthodontics and dentofacial orthopedics certificate or degree in 2025 and 7,482 holding one in oral and maxillofacial surgery.
Both are credential counts β HPI counts a dentist in every practice area in which they hold a certificate or degree, so a dentist with two specialty credentials appears in each.
The neighboring surgical match-up has its own page: oral surgeon vs endodontist, where the line is surgery versus the tooth's interior rather than surgery versus alignment.
Pay: two direct federal series, two older survey medians
This is one comparison where both sides get their own federal number.
BLS publishes separate wage series for only a handful of dentist occupations, and orthodontists and oral and maxillofacial surgeons are two of them.
The May 2025 medians: $289,140 for orthodontists and $352,220 for oral and maxillofacial surgeons.
For context within the same release, prosthodontists sit at $311,180, general dentists at $170,950, and the grouped "dentists, all other specialists" line at $224,990.
Because the two titles are separate occupation lines, a search for an "orthodontist surgeon salary" resolves into two different measurements β there is no single figure for both roles, and neither median is a proxy.
What the BLS wage measure covers is the catch.
BLS wage estimates exclude the self-employed and the owners and partners in unincorporated firms β so income from self-employed dentists and from unincorporated practices' owners and partners sits outside those medians, on both sides of the comparison.
ADA HPI's net income survey covers owners and employees together, but its specialty medians are older.
The most recent reportable figures for private-practice specialists are $445,120 for oral and maxillofacial surgeons, from the 2022 survey year, and $242,630 for orthodontists, from 2024.
HPI suppressed the 2025 figures for both specialties because there were too few observations, and the reportable values swing year to year on those small samples.
Read carefully, the direction is consistent β the OMS figure sits above the orthodontics figure in both the federal wage series and the survey data β but the comparison is not like-for-like: the measures differ (wage versus net income), the survey years differ, and the survey publishes no owner-versus-associate split for either specialty.

Handle these numbers with care
Lifestyle: what the data does β and doesn't β say
Start with the honest part: our research found no reliable published data on call schedules, weekly hours or after-hours coverage for either specialty.
Any claim that one specialty's lifestyle beats the other's is not something the available data can settle, so treat hour-for-hour comparisons that circulate online as anecdotes.
What the data does cover is the training runway you would be signing up for.
On the 2025-26 averages, an oral surgery residency runs 53.1 months against 31.2 for orthodontics β and the years are financed differently: 90 of 103 OMS programs paid an average first-year stipend of $66,596, while 57 of 69 orthodontics programs charged an average first-year tuition of $55,640.
Longer program, and more often a paid one, on the OMS side.
Day to day, the schedule follows the work: orthodontic care is delivered through planned visits across a course of treatment, and surgical care through discrete procedures with anesthesia built into the training.
How that lands on a calendar β evenings, call, hospital time β is set practice by practice, so ask it directly of residency programs and of employers in interviews, and weigh posted schedules over general impressions.
The market you graduate into is the one part that is measured.
BLS counted 7,100 orthodontist jobs and 5,600 oral and maxillofacial surgeon jobs in 2025 β employment estimates measured differently from HPI's credential counts above β and projects 6% employment growth from 2025 to 2035 for both occupations.
How orthodontists and oral surgeons work together
The clearest collaboration is the orthognathic case: treatment for a patient whose bite problem is skeletal rather than purely dental.
The orthodontics definition puts skeletal abnormalities of the orofacial structures inside the specialty's scope, and the OMS definition puts surgical treatment of defects of the hard and soft tissues inside its own β so one case can draw on both.
On such a case the two scopes are complementary.
The orthodontist's side is the alignment work β moving teeth and arches so the jaws can meet correctly β and the oral surgeon's side is the surgical phase on the jaws and surrounding tissues.
Choosing one career keeps you on that side of the loop: the orthodontist runs the alignment plan, the oral surgeon the operative phase.
How any specific case is sequenced and divided β including whether alignment continues after surgery β is a decision for the treating clinicians and their state licensing rules, not something a career guide settles.
If you sit on the employer side of that relationship β a practice building out its orthodontic capacity or its referral network β the employer-side guide covers hiring an orthodontist.
