There are 12 officially recognized dental specialties in the United States, plus general dentists who handle the bulk of everyday care. Most people will only ever need two or three types of dentists in their lifetime, but knowing what each one does helps you understand why your dentist might refer you to a specialist and what to expect when they do.
General Dentists
General dentists are the primary care providers of the dental world. They perform cleanings, fillings, crowns, extractions, whitening, and routine X-rays. They also screen for oral cancer, gum disease, and cavities at your regular checkups. When a problem falls outside their training or requires advanced techniques, they refer you to one of the recognized specialties below.
Most general dentists complete four years of dental school after their undergraduate degree, earning either a DDS (Doctor of Dental Surgery) or DMD (Doctor of Medicine in Dentistry). The two degrees are functionally identical.
Orthodontists
Orthodontists straighten teeth and correct bite problems. They treat conditions like overbites, underbites, crossbites, open bites, and overcrowding using metal braces, clear aligners, headgear, and sometimes coordinating with surgeons for jaw correction. If your upper and lower teeth don’t line up properly when you close your mouth, an orthodontist is the specialist who fixes that. Treatment typically spans one to three years depending on severity.
Oral and Maxillofacial Surgeons
Oral surgeons handle procedures that go beyond what a general dentist can do in the chair. Their scope includes wisdom tooth extractions, dental implant placement, jaw surgery to correct alignment or breathing problems, bone grafting, cleft lip and palate repair, reconstructive facial surgery, and even surgery for sleep apnea. They complete four to six years of surgical residency training after dental school, and many also hold medical degrees. If you need teeth removed under general anesthesia or have a fractured jaw, this is the specialist you’ll see.
Periodontists
Periodontists specialize in the gums and bone that support your teeth. They’re the go-to specialists for gum disease, which affects roughly half of adults over 30. Their nonsurgical treatments include deep cleanings called scaling and root planing, where they clean beneath the gumline and smooth the root surfaces so bacteria can’t reattach easily.
When gum disease has progressed further, periodontists perform surgical procedures: pocket reduction surgery to clean damaged bone and reposition gum tissue, bone grafting to rebuild areas destroyed by infection, and gum grafting to cover exposed roots where gums have receded. During a gum graft, they typically take tissue from the roof of your mouth and stitch it over the receded area. They also place dental implants, since implants require healthy bone and gum tissue to succeed.
Endodontists
Endodontists focus on the inside of the tooth, specifically the pulp and nerve tissue. Root canals are their signature procedure. When a cavity or crack reaches deep enough to infect the pulp, an endodontist removes the damaged tissue, cleans the inner canals, and seals the tooth to prevent reinfection. They also perform surgical root procedures when standard root canals aren’t enough and place dental implants when a tooth can’t be saved. General dentists do perform root canals, but endodontists handle the complex cases, like teeth with unusual anatomy, prior failed treatments, or severe infections.
Prosthodontists
Prosthodontists restore and replace missing or damaged teeth. They handle dentures, bridges, crowns, veneers, and full-mouth reconstructions. If you’ve lost multiple teeth, have severe wear from grinding, or need a complete smile rebuild, a prosthodontist designs the treatment plan and manages the process. Some also create maxillofacial prosthetics for patients who’ve lost parts of their jaw or face to cancer surgery or trauma. This is one of the fastest-growing dental specialties, driven in part by rising patient interest in cosmetic improvements.
Pediatric Dentists
Pediatric dentists treat patients from infancy through adolescence. Their offices, training, and approach are designed around children’s behavior, development, and anxiety management. Beyond routine care for kids, they have specific training in treating children with special health care needs, including developmental disabilities, complex medical conditions, and behavioral challenges that make dental visits difficult. They coordinate with a child’s other medical providers when sedation or special precautions are needed. Once patients reach adulthood, they typically transition to a general dentist or another specialist.
Oral and Maxillofacial Pathologists
These specialists diagnose diseases of the mouth, jaw, and face. If your dentist finds an unusual sore, lump, or discoloration and sends a tissue sample to a lab, an oral pathologist is often the one examining it under a microscope. They identify oral cancers, autoimmune conditions, infections, and cysts. You’re unlikely to visit one in person, but their work happens behind the scenes whenever a biopsy is needed.
Oral and Maxillofacial Radiologists
Oral radiologists are the imaging experts of dentistry. They specialize in taking and interpreting advanced scans of the teeth, jaws, and surrounding structures. While general dentists read standard X-rays, radiologists handle complex imaging like cone-beam computed tomography (a 3D scan of your jaw) that has significantly improved the ability to diagnose infections, tumors, and jaw abnormalities. They also advise on radiation safety. Like pathologists, they mostly work behind the scenes rather than seeing patients directly.
Orofacial Pain Specialists
Orofacial pain specialists diagnose and treat chronic pain in the jaw, mouth, face, head, and neck. Their most common cases involve temporomandibular disorders (TMJ/TMD), where the jaw joint and surrounding muscles cause persistent pain, clicking, or limited movement. After dental cavities and gum disease, musculoskeletal problems like TMD are the most common source of mouth and face pain. These specialists use MRI and other tools to pinpoint the cause and develop treatment plans that may include physical therapy, splints, or medication management. This is one of the newer recognized specialties.
Oral Medicine Specialists
Oral medicine specialists manage dental care for patients with complex medical conditions. If you have a disease that affects your mouth (like autoimmune disorders that cause chronic sores) or take medications that create dental complications (like drugs that cause severe dry mouth or bone loss in the jaw), an oral medicine specialist coordinates your care. Their residency training is a minimum of two years, with some programs extending to five years when combined with advanced research degrees.
Dental Anesthesiologists
Dental anesthesiologists manage sedation and anesthesia during dental procedures. They monitor your pain control, anxiety levels, and vital signs, particularly during longer or more invasive treatments. They’re especially valuable for patients with medical conditions that make sedation risky, patients with extreme dental anxiety, and children or individuals with special needs who can’t tolerate standard dental visits. This specialty has been growing as more complex procedures are performed in dental offices rather than hospitals.
Dental Public Health Specialists
Dental public health specialists work at the community level rather than treating individual patients. They design and run programs like community water fluoridation, school-based sealant programs, and fluoride rinse initiatives. They collect data on dental disease in populations, develop health policy, and work to improve access to care for underserved groups. Their focus is prevention and education on a large scale, partnering with local health departments and government agencies.
What About Cosmetic Dentists?
Cosmetic dentistry is not a recognized specialty. Any general dentist can market themselves as a cosmetic dentist. Procedures like teeth whitening, veneers, and smile makeovers are performed by general dentists, prosthodontists, and others. There’s no separate board certification or residency for cosmetic work. If you’re seeking major aesthetic changes, a prosthodontist has the most advanced training in that area, but many general dentists develop strong skills in cosmetic procedures through continuing education.
