There are 12 dental specialties recognized by the National Commission on Recognition of Dental Specialties and Certifying Boards, the body that officially designates specialty areas within dentistry in the United States. Each requires additional years of residency training beyond dental school. Most general dentists can handle routine care, but these specialists focus on specific conditions, patient populations, or treatment techniques that go beyond the scope of everyday practice. Here’s what each one does and when you might be referred to one.
1. Endodontics
Endodontists specialize in the inside of your teeth, specifically the soft tissue (called the pulp) that contains nerves and blood vessels, along with the root structures beneath. If you’ve ever had a root canal, an endodontist likely performed it. They treat infections deep within a tooth, manage dental trauma like a cracked or knocked-out tooth, and perform surgical procedures on the root tip when a standard root canal isn’t enough. There are roughly 5,685 active endodontists in the U.S.
2. Orthodontics and Dentofacial Orthopedics
This is the specialty behind braces, clear aligners, and other devices that correct misaligned teeth and jaws. Orthodontists diagnose and treat crooked teeth, overbites, underbites, and skeletal imbalances in the jaw. The “dentofacial orthopedics” part of the name refers to guiding the growth and development of facial bones, which is why orthodontic treatment often starts in childhood or adolescence when the jaw is still growing. Adults benefit too, but the approach may differ.
3. Periodontics
Periodontists focus on the structures that support your teeth: the gums, the bone underneath, and the connective tissue that holds everything in place. Gum disease is their primary territory. In its early stages, your general dentist can manage it, but advanced cases with deep pockets of infection, bone loss, or receding gums typically require a periodontist. They also place dental implants, since implant success depends heavily on the health of the surrounding bone and tissue.
4. Prosthodontics
Prosthodontists restore and replace missing or damaged teeth. Their toolkit includes crowns, bridges, full and partial dentures, dental implants, and custom restorations like inlays and onlays (used when a tooth is too damaged for a filling but doesn’t need a full crown). They also design oral splints and night guards for TMJ disorders. If you’ve lost several teeth or need a full-mouth reconstruction, a prosthodontist is the specialist who plans and executes that level of rehabilitation.
5. Oral and Maxillofacial Surgery
Oral surgeons handle the most complex surgical procedures in dentistry. This includes wisdom tooth extractions, corrective jaw surgery, treatment of facial trauma (broken jaws, fractured cheekbones), removal of tumors or cysts in the jaw, and surgical placement of dental implants in complicated cases. Many oral surgeons train in hospital settings alongside medical residents and can administer general anesthesia. With about 7,424 active practitioners in the U.S., this is one of the larger specialty groups.
6. Pediatric Dentistry
Pediatric dentists provide dental care for infants, children, and adolescents, including those with special health care needs. Their training, which involves a two-year residency after dental school, covers child behavior management, growth and development of the teeth and jaws, and preventive strategies tailored to younger patients. Their offices are typically designed to reduce anxiety in kids, and they’re trained to handle the unique challenges of treating a nervous five-year-old or a teenager with developmental disabilities.
7. Oral and Maxillofacial Pathology
These specialists are the diagnostic detectives of dentistry. When a dentist finds an unusual lesion, lump, or discoloration in your mouth, an oral pathologist examines tissue samples under a microscope to determine what it is. They identify oral cancers, precancerous conditions, infections, and autoimmune diseases that show up in the mouth. You likely won’t visit one directly. Instead, your dentist or surgeon sends a biopsy to the pathologist’s lab for analysis.
8. Oral and Maxillofacial Radiology
Oral radiologists are dentistry’s imaging specialists. While every dentist takes X-rays, these specialists have advanced training in interpreting complex imaging like cone-beam CT (CBCT) scans, which create 3D views of your teeth, jaw, and surrounding structures. They’re consulted when standard X-rays don’t provide enough information, such as before implant placement, jaw surgery, or when an unusual finding needs closer evaluation. They also focus on radiation safety and ensuring patients receive the lowest effective dose.
9. Dental Public Health
This specialty operates at the population level rather than the individual patient level. Dental public health specialists design community programs to prevent oral disease, analyze epidemiological data, shape health policy, and work to improve access to dental care for underserved groups. They often work for government agencies, health departments, or academic institutions. Their training includes epidemiology, biostatistics, health policy, and behavioral science, and many earn a master’s in public health alongside their specialty certification.
10. Oral Medicine
Oral medicine specialists bridge the gap between dentistry and medicine. They manage patients whose medical conditions complicate dental care, such as those undergoing chemotherapy, people with autoimmune disorders that cause painful mouth sores, or patients on blood-thinning medications who need careful coordination before dental procedures. They also diagnose conditions like chronic dry mouth from medication side effects and oral manifestations of systemic diseases. Their approach is primarily nonsurgical.
11. Orofacial Pain
This specialty focuses on chronic pain in the jaw, mouth, face, head, and neck. TMJ disorders are a major part of their practice, but they also diagnose and treat nerve-related facial pain, chronic headaches linked to dental or jaw problems, and pain conditions that don’t have an obvious dental cause. Patients often reach an orofacial pain specialist after seeing multiple providers without finding a clear diagnosis. These specialists use a combination of physical therapy approaches, behavioral strategies, medications, and oral appliances.
12. Dental Anesthesiology
Dental anesthesiologists manage sedation and pain control during dental procedures. They’re especially valuable for patients who need deep sedation or general anesthesia but are being treated in a dental office rather than a hospital operating room. This includes patients with severe dental anxiety, young children who can’t cooperate for lengthy procedures, and people with medical complexities that make sedation riskier. Because dentists work inside the airway, having a dedicated anesthesiologist monitor the patient’s breathing and vital signs while the treating dentist focuses on the procedure adds a significant safety layer.
How Specialists Differ From General Dentists
Every dental specialist first completes four years of dental school to earn a DDS or DMD degree, the same degree your general dentist holds. After that, they complete an additional residency program ranging from two to six years depending on the specialty. Oral and maxillofacial surgery residencies are the longest, often lasting four to six years, while pediatric dentistry requires a minimum of two years. Out of roughly 159,562 general dentists practicing in the U.S., specialists make up a smaller but critical portion of the dental workforce.
Your general dentist serves as the first point of contact for most dental issues and refers you to a specialist when a problem falls outside their training or when a case is unusually complex. Some situations make the referral obvious: a child goes to a pediatric dentist, an impacted wisdom tooth goes to an oral surgeon. Others are less intuitive. Persistent jaw pain that doesn’t respond to basic treatment, for example, might eventually lead to an orofacial pain specialist after your dentist and perhaps an ENT have ruled out simpler causes.
