The 12 Dental Specialties Explained

There are 12 recognized dental specialties.

Recognition in the United States is granted by the American Dental Association's National Commission on Recognition of Dental Specialties and Certifying Boards (NCRDSCB), which also recognizes the certifying boards — 11 of them, one for every specialty except oral and maxillofacial radiology, which has no board on the Commission's recognized list.

ADA News reported in September 2026 that a certifying board for oral and maxillofacial radiology has applied for recognition, so the board count may change.

Recognition is what separates a specialty from an area of clinical interest.

A dentist who does implants all day, or who markets a practice around cosmetic work, may be highly skilled — but implantology, cosmetic dentistry, and sleep dentistry are not recognized specialties — none of them is on the Commission's recognized list, and no recognized certifying board stands behind those labels.

The list has also grown, which is the usual source of confusion.

Per the NCRDSCB's April 2026 annual report, the newest three certifying boards — dental anesthesiology's, oral medicine's, and orofacial pain's — were recognized in 2020, 2021, and 2022, while the boards for oral and maxillofacial surgery, pediatric dentistry, periodontology, and prosthodontics all date to 1948.

The three newest fields are recent enough that plenty of textbooks, school pages, and older articles predate them and still say there are nine dental specialties.

Nine is not wrong so much as out of date.

One more role gets confused for a specialty and isn't: the dental lab technician.

It's a distinct, non-clinical member of the dental team — no residency, no diagnosing or treating patients, no certifying board on this list — that fabricates the crowns, bridges, and dentures several of the specialties below prescribe.

Here is the full list of dental specialist types, with what each specialty actually treats.

The first six are the largest fields and the treatment specialties a general practice works alongside; the last six are smaller fields organized differently — the later sections take them in turn.

• Orthodontics and dentofacial orthopedics — aligning teeth and correcting bite and jaw relationships with braces, aligners, and growth-guiding appliances.
• Oral and maxillofacial surgery — surgery of the mouth, jaws, and face: impacted and complex extractions, surgical implant placement, corrective jaw surgery, and facial trauma.
• Endodontics — the inside of the tooth: root canal treatment, retreatment of failed root canals, and surgery at the root tip.
• Pediatric dentistry — comprehensive oral care for infants, children, and adolescents, including patients with special health care needs.
• Periodontics — the gums and the bone that support the teeth: gum disease, soft-tissue and bone grafting, and surgically placing implants.
• Prosthodontics — restoring and replacing teeth: complex crowns and bridges, dentures, restoring implants, full-mouth reconstruction, and maxillofacial prosthetics.
• Oral and maxillofacial pathology — diagnosing diseases of the mouth and jaws, largely through biopsy and microscopic examination.
• Oral and maxillofacial radiology — producing and interpreting images and data from every imaging modality used to diagnose and manage diseases and conditions of the mouth and jaws.
• Dental public health — preventing and controlling dental disease through organized community efforts, with the community rather than the individual as the patient.
• Dental anesthesiology — managing pain, anxiety, and overall patient health during dental treatment with anesthesia and sedation, including for the very young and patients with special health care needs.
• Oral medicine — the oral health care of medically complex patients, and the diagnosis and management of medically related diseases and conditions of the oral and maxillofacial region.
• Orofacial pain — the diagnosis, management, and treatment of pain disorders of the jaw, mouth, face, head, and neck.

Every one of these is reached the same way: dental school first, then an accredited residency in that field — and eleven of the twelve then certify with their field's recognized board.

The 12 types vary enormously in size.

The ADA Health Policy Institute's Supply of Dentists data counts professionally active U.S. dentists by the specialty certificate or degree they hold, and its 2025 counts run from 10,844 dentists in orthodontics and dentofacial orthopedics down to 54 in oral medicine.

Two caveats before reading the table.

The counts overlap slightly: HPI counts a dentist under every practice area in which they hold a certificate or degree, so a dentist with two specialty credentials appears twice.

And HPI only began tracking dental anesthesiology, oral medicine, and orofacial pain after those specialties were recognized, so the three newest types have shorter counting histories than the rest.

The shape of the table is the career signal.

The six largest types are the patient-facing, treatment-delivering specialties; each of the six smallest counts its practitioners in the hundreds or fewer, and their careers are organized differently — the next two sections take the two groups in turn.

For context, the same 2025 data counted 161,733 professionally active U.S. dentists in general practice out of 205,088 professionally active dentists.

Six specialties are the treatment fields a general practice works alongside — orthodontics, pediatric dentistry, oral and maxillofacial surgery, endodontics, periodontics, and prosthodontics — though the work does not all arrive the same way.

Orthodontics and pediatric dentistry are largely direct-to-patient, with families booking the specialist themselves, while endodontics, periodontics, oral and maxillofacial surgery, and prosthodontics are the referral-driven fields built around cases general dentists send them.

The split matters if you are choosing a field.

A referral-driven specialty depends on relationships with the general dentists who send cases, which shapes marketing, location, and how a practice grows.

A direct-to-patient specialty competes for the patient directly.

Scope overlaps at the edges.

A general dentist may do straightforward root canals, simple extractions, or clear-aligner cases in house and refer the difficult versions out, so the line between what a practice keeps and what it refers moves with the dentist's training and comfort — the subject of general dentist vs. specialist.

Implants are the clearest example — how placement and restoration divide between periodontists, oral surgeons, prosthodontists, and general dentists is covered in periodontist vs. prosthodontist.

The specialty mix also changes who a practice hires — a surgical office and an orthodontic office run on different assistant and coordination roles.

If you are a dental assistant or a treatment coordinator choosing where to work, the specialty of the practice shapes your day as much as its size does.

The other six specialties are smaller and less visible to patients, which is exactly why they are worth knowing about as career paths — they are the parts of dentistry that look least like a private office with operatories.

Oral and maxillofacial pathology and oral and maxillofacial radiology are diagnostic fields.

The pathologist identifies and diagnoses disease of the mouth and jaws from biopsy and other specimens; the radiologist produces and interprets images that other clinicians use to diagnose and manage disease.

Both are consultative fields — their work sits behind the care other dentists deliver rather than at the chair.

Dental public health is the population-level specialty: preventing and controlling dental disease and promoting dental health through organized community efforts, with the community — not the individual patient — as the patient.

The NCRDSCB's definition includes dental health education of the public, applied dental research, and the administration of group dental care programs, and one accredited route into the field — the one-year residency — requires a Master of Public Health or comparable degree before it even starts.

Dental anesthesiology covers the management of pain, anxiety, and overall patient health during dental treatment with anesthesia and sedation, including for the very young and patients with special health care needs.

Its practice settings are distinctive for dentistry: in a 2018 survey of American Society of Dentist Anesthesiologists members, 58.7% practiced as mobile providers — bringing anesthesia services into other dentists' offices — and 32.2% provided care in an academic environment.

Oral medicine handles the medically complex end of the mouth: the specialty is responsible for the oral health care of medically complex patients and for diagnosing and managing medically related diseases and conditions of the oral and maxillofacial region.

It sits at the dental-medical border, and its CODA training standards require rotations through medical services and hospital rounds.

Orofacial pain is the newest kind of practice most patients have never heard of.

It covers the diagnosis, management, and treatment of pain disorders of the jaw, mouth, face, head, and neck, and its own specialty definition commits it to improving access to interdisciplinary care.

It is closer to a chronic-pain clinic than a restorative practice.

The common structure across all 12 is the same.

You finish dental school with a DDS or DMD, then complete a residency accredited by the Commission on Dental Accreditation (CODA) in that specialty, running roughly two to six years depending on the field — oral and maxillofacial surgery is the longest, with some programs also awarding a medical degree.

Admission is the hard part for the competitive fields, and several run through a formal match — see which dental specialty is hardest to match into for the applicant and position counts, specialty by specialty.

After residency, most specialists pursue certification from their field's board — for example the American Board of Orthodontics, the American Board of Oral and Maxillofacial Surgery, the American Board of Endodontics, or the American Board of Pediatric Dentistry.

Board certification is voluntary — the NCRDSCB describes it as a demonstration of lifelong learning and continued professional development, not a legal requirement to practice.

The mechanics of residencies, the match, and certification are covered in depth in dental residency and board certification, and the specialty-by-specialty paths in guides like how to become an orthodontist and how to become an oral surgeon.

One distinction is worth keeping straight: a residency is what makes someone a specialist, not a weekend course or a manufacturer's certificate.

Continuing-education credentials are real and often valuable, but they are not specialty training and no certifying board stands behind them.

General dentistry is not a 13th specialty.

It is the broad primary-care scope every dentist starts with, and most dentists practice in it — 161,733 of the 205,088 professionally active U.S. dentists counted in 2025 — diagnosing, restoring, extracting, and managing a patient's overall oral health while sending out the cases that call for depth.

A general dentist can legally perform a great deal of what specialists do; what a dentist cannot freely do is announce a specialty they have not trained in, because state dental boards regulate how specialty credentials are advertised and those rules vary by state.

Skill and title are separate questions.

Pay differs too.

Specialists are tracked under separate federal occupational codes from general dentists and generally earn more than general dentists, though the ranges overlap and ownership matters as much as the letters after a name.

Which dental specialty pays the most ranks the dental SOC codes side by side.

See the dentist salary guide for the general-dentist benchmark, and the orthodontist and oral surgeon salary guides for two of the specialty figures.

If you are weighing the decision itself, general dentist vs. specialist covers the trade-off, and what a dentist does covers the base role.
