Most people know a dentist fixes teeth, but dentistry includes several distinct specialties, each focused on a different part of oral health. This guide explains the main types of dentists — general dentists, orthodontists, periodontists, endodontists, oral surgeons, and pediatric dentists — and describes, at concept level, what each one focuses on.
The General Dentist: Your Primary Oral Health Provider
A general dentist is the entry point to dental care for most people and the professional most of us picture when we hear the word "dentist." General dentists provide routine examinations, professional cleanings, fillings for cavities, simple extractions, crowns, and preventive guidance on brushing, flossing, and diet. Think of the general dentist the way you think of a family doctor: the clinician who knows your overall situation, handles everyday problems, and decides when something needs a specialist's attention.
General dentists also act as coordinators. When a condition falls outside their training — a complex root canal, advanced gum surgery, or a complicated wisdom tooth extraction — they refer the patient to the appropriate specialist and often continue to oversee the broader treatment plan. If you are unsure which dental professional fits your situation, starting with a general dentist is the conventional first step. Our overview of what a dentist does covers the general dentist's role in more depth.
Orthodontist: Alignment and Bite Specialist
An orthodontist focuses on the alignment of the teeth and jaws — how the teeth are positioned and how the upper and lower teeth meet when you bite. The treatments most associated with orthodontics are braces and clear aligners, which gradually move teeth into better positions over months or years. Orthodontists also treat jaw-growth issues in children and adolescents, and they manage retainers after active treatment ends.
People usually end up with an orthodontist through a referral from a general dentist, often after a routine exam reveals crowding, gaps, overbite, underbite, or crossbite. Orthodontic treatment is not purely cosmetic: misaligned teeth can be harder to clean, wear unevenly, and strain the jaw. Our comparison of braces versus aligners explains the two main approaches at a high level.
Periodontist: Gum and Supporting-Structure Specialist
A periodontist specializes in the gums and the bone that supports the teeth — the periodontium. Periodontists diagnose and treat gum disease at its more advanced stages, perform procedures such as scaling and root planing (deep cleaning below the gumline), gum grafts, and surgery to reduce deep pockets around teeth. They also place dental implants, since implant placement depends heavily on the condition of the underlying bone and gum tissue.
A general dentist typically refers a patient to a periodontist when gum disease has progressed beyond what routine treatment can manage, or when bone loss around teeth is a concern. Some periodontists also focus on cosmetic gum procedures, such as reshaping an uneven gumline. Prevention remains relevant at every stage: consistent daily oral hygiene and regular professional cleanings are the main defenses against the conditions periodontists treat.
Endodontist: Inside-the-Tooth Specialist
An endodontist focuses on the interior of the tooth — the pulp, which contains nerves and blood vessels — and the tissues surrounding the tooth root. The treatment most associated with endodontics is the root canal, which removes infected or damaged pulp from inside the tooth, cleans and seals the canal space, and preserves a tooth that would otherwise need extraction.
General dentists perform many routine root canals themselves, but they refer cases with complex root anatomy, retreatments of previously treated teeth, or difficult-to-reach areas to endodontists. Endodontists use specialized microscopes and imaging to work inside teeth with high precision. If your dentist mentions a referral for a root canal, an endodontist is the likely destination — our plain-language guide to root canal treatment explains the concept in more detail, though practices vary in who performs it.
Oral and Maxillofacial Surgeon: Surgical Specialist
Oral and maxillofacial surgeons handle surgical procedures of the mouth, jaws, and face. Common procedures include surgical extraction of impacted wisdom teeth, corrective jaw surgery, treatment of facial trauma, and complex dental implant cases. They are trained in anesthesia and sedation, which is why patients needing deeper sedation for surgery are often referred to them.
Not every extraction needs an oral surgeon — general dentists remove many teeth themselves. Referrals happen when a case is expected to be complicated: a wisdom tooth angled against its neighbor, a tooth fused to surrounding bone, or a patient whose medical history requires a surgical setting. Oral surgeons typically work closely with the referring dentist and the patient's physician to plan care safely.
Pediatric Dentist: Children's Dental Specialist
A pediatric dentist specializes in the oral health of infants, children, and teenagers. Their training covers the development of children's teeth and jaws, behavior management for young patients who may be anxious or uncooperative, and conditions specific to growing mouths — such as thumb-sucking effects, early tooth decay (sometimes called baby-bottle tooth decay), and the timing of permanent tooth eruption.
Many families see a general dentist for children without issue, and general dentists treat children routinely. A pediatric dentist referral makes sense for very young children, children with significant dental anxiety, or children with special healthcare needs. Pediatric practices are usually designed around children, with communication styles and office environments adapted to them.
Prosthodontist: Restoration and Replacement Specialist
A prosthodontist specializes in restoring and replacing teeth: crowns, bridges, dentures, veneers, and dental implants. While general dentists also place crowns and dentures, prosthodontists handle the most complex cases — full-mouth rehabilitation, patients who have lost many teeth, congenital conditions affecting tooth formation, and cases where bite alignment and aesthetics must be rebuilt together.
If a treatment plan involves replacing several teeth or rebuilding the bite, a general dentist may refer to a prosthodontist for planning and execution. Prosthodontists often work as part of a team with oral surgeons and periodontists when implants are involved.
Other Recognized Specialties
A few additional specialties complete the picture:
- Dental anesthesiologist — manages pain, anxiety, and sedation during dental procedures.
- Dental public health specialist — focuses on community-level oral health programs and prevention policy.
- Oral pathologist — diagnoses diseases of the mouth and jaws through laboratory analysis of tissue samples.
- Oral radiologist — interprets complex dental imaging.
Most patients will never interact directly with these specialists, but they are part of the professional infrastructure behind dental care.
How Referrals Work in Practice
Understanding specialties matters because referrals are a normal part of dental care, not a sign that something is seriously wrong. A general dentist who refers you to a specialist is doing exactly what good primary care should do: matching the problem to the clinician with the most relevant training. The referring dentist typically sends records and X-rays ahead, and the specialist reports findings back, so your care stays coordinated.
You can always ask questions about a referral: why this specialist, what the specialist will do differently, and what information will be shared. A clear referral with a stated reason is better than a vague one — and if cost or logistics are a concern, discuss them with the referring dentist before the specialist visit.
Choosing Where to Start
For most adults and children without a specific diagnosed condition, the general dentist is the right starting point. The general dentist evaluates, treats what falls within routine care, and routes everything else. Specialty visits usually begin with that evaluation.

FAQ
Do I need a referral to see a dental specialist?
It depends on the practice and your insurance plan. Many specialists accept patients directly, but some insurance plans require a referral from a general dentist before they cover specialty care. Even when not required, a referral helps because the specialist receives your records and knows exactly what to evaluate. Check your plan's rules and ask the general dentist whether a referral makes sense for your situation.
What is the difference between an orthodontist and a regular dentist?
An orthodontist is a dentist who completed additional years of specialty training focused on tooth and jaw alignment. A general dentist may handle simple alignment issues, but orthodontists manage the full range: braces, clear aligners, jaw-growth guidance in children, and retention after treatment. Think of it as the difference between a family doctor and a cardiologist — related fields, different depth of focus.
Which dentist treats gum disease?
Early gum disease (gingivitis) is usually managed by a general dentist or dental hygienist through cleanings and improved home care. More advanced gum disease (periodontitis), involving bone loss or deep pockets around teeth, is typically treated by a periodontist. The general dentist monitors gum health at every checkup and refers when the condition progresses beyond routine management. If you notice persistent bleeding, bad breath, or receding gums, mention it at your next checkup so it can be evaluated early.
Can a general dentist do a root canal?
Yes, general dentists perform many root canal treatments, particularly on front teeth with straightforward anatomy. They refer complex cases — molars with curved or multiple canals, retreatments, or teeth that are difficult to access — to endodontists, who have additional training and specialized equipment for exactly those situations. The decision usually depends on the tooth and the dentist's assessment of complexity.
How do I know if my child needs a pediatric dentist?
Many children receive excellent care from general dentists. Consider a pediatric dentist for very young children (under three), children with significant dental anxiety, children with special healthcare needs, or complex developmental concerns. Pediatric dentists have extra training in child behavior and growth. Either way, the standard guidance is a first dental visit around the first birthday or when the first tooth appears — discuss timing with a dental professional.
