Types of Dentists and What They Do

Choosing the right dentist can feel confusing when names and specialties sound alike, so this guide gives you a simple map of who handles what.

You’ll see which dentist is usually your first stop, when a specialist offers a better fit, and how each role supports your long-term oral health. By the end, you’ll know how to match your symptoms or goals with the right provider.

Remember, your situation is always unique, so think of this as a starting point to help you plan your next visit with more confidence.

Different Types of Dentists

General and family dentists handle most day-to-day oral health needs, while 12 ADA-recognized specialties cover more advanced problems.

These titles reflect the training and scope of these professionals, helping you understand who’s best for your teeth, gums, bite, or jaw concerns. Because each dentist offers different care, a quick overview can make your next decision easier.

The common dental provider roles are:

• General dentist ⁠— Handles exams, cleanings, fillings, and many restorations for most ages.
  
• Family dentist ⁠— A general dentist who treats all ages and offers a single home for household care.
  
• Pediatric dentist ⁠— Provides dental care for infants, children, teens, and those with special health needs.
  
• Endodontist ⁠— Treats tooth-nerve problems, including complex root canal therapy.
  
• Periodontist ⁠— Specializes in gum disease, supporting tissues, and related surgical care.
  
• Orthodontist ⁠— Corrects bite, jaw alignment, and tooth position to improve function and long-term health.

What is the Difference Between General and Family Dentistry?

General and family dentists share the same training, yet they differ in who they routinely see. A family dentist is a general dentist who welcomes patients of all ages, making them a convenient option for households with children or older adults.

Care for young children often needs a gentler approach, because developmental changes and behavior can shape the visit. A family dentist would be more comfortable managing these stages, while a general dentist may choose to see only older children and adults.

This small distinction helps you decide whether you want a single office for everyone or a practice that focuses mainly on teens and adults. If your child is very young or has special health needs, your dentist may suggest a pediatric dentist for extra support.

Who Should You See First?

A general or family dentist is usually your starting point because they provide comprehensive checkups, preventive care, basic restorations, and guidance on when you may need advanced treatment.

They are trained to address most routine issues, so they naturally function as your “dental home.” This reflects the structure of U.S. dentistry, where most practitioners are generalists who support your ongoing oral health and coordinate specialist care when cases become more complex.

Some situations call for an immediate specialist visit, such as:

• Dental trauma
• Rapidly increasing swelling
• Concerns about an impacted tooth

These cases often need advanced imaging or surgical planning, which a specialty office is equipped to provide. If any red-flag symptoms worsen—like intense pain with fever or spreading swelling—reach out right away for same-day guidance.

To get started, schedule a full exam so your dentist can confirm what type of care you need next.

12 Recognized Dental Specialties

The United States currently recognizes 12 dental specialties, each overseen by the National Commission on Recognition of Dental Specialties and Certifying Boards. 

These specialties exist because certain problems require additional training, specialized tools, or procedures beyond what is taught in dental school.

Knowing the official specialties also helps you understand why some areas—like cosmetic or implant dentistry—are considered practice focuses rather than formal specialties.

Here’s a clear look at each specialty:

• Dental Anesthesiology ⁠— Manages pain, anxiety, and sedation for dental and surgical procedures.
  
• Dental Public Health ⁠— Focuses on community-level disease prevention and oral health programs.
  
• Endodontics ⁠— Treats conditions of the dental pulp and tissues around the root tip.
  
• Oral and Maxillofacial Pathology ⁠— Diagnoses diseases of the mouth, jaws, and related structures.
  
• Oral and Maxillofacial Radiology ⁠— Interprets dental imaging, including 3-D scans and radiographic studies.
  
• Oral and Maxillofacial Surgery ⁠— Performs surgical treatments for teeth, jaws, trauma, and facial conditions.
  
• Oral Medicine ⁠— Manages medically related oral diseases and complex health interactions.
  
• Orofacial Pain ⁠— Treats chronic jaw, facial, head, and neck pain conditions.
  
• Orthodontics and Dentofacial Orthopedics ⁠— Corrects bite and jaw alignment to improve function and growth.
  
• Pediatric Dentistry ⁠— Provides comprehensive care for infants, children, and adolescents.
  
• Periodontics ⁠— Treats gum disease and supports the tissues that anchor teeth.
  
• Prosthodontics ⁠— Restores or replaces missing or damaged teeth with advanced rehabilitation.

Match these one-liners with your symptoms or goals, then ask your dentist whether specialty care is the right next step.

Common Services and Providers

Dentists share many services, but some treatments are better suited for specialists. General dentists provide routine exams, cleanings, fillings, and most everyday restorations, while specialists handle cases that require deeper expertise.

This shared model helps you get comprehensive care without having to guess where to start. A few services, like root canal therapy or gum surgeries, are often referred to a specialist because the procedures are more complex or require advanced equipment. 

Endodontists perform far more root canal treatments each week than general dentists do, so their experience can be especially helpful for difficult cases. Simple extractions, crowns, and fillings are usually handled by a general dentist, while surgical extractions and complex implant cases are handled by surgeons or prosthodontists.

Here’s a quick guide that shows where common treatments usually fall:

• Routine care ⁠— Exams, cleanings, X-rays, and fluoride treatments are provided by general and family dentists.
  
• Restorations ⁠— Fillings, crowns, dentures, and many implant restorations start with a general dentist, while complex full-mouth cases go to prosthodontists.
  
• Root canal therapy ⁠— General dentists treat straightforward cases; endodontists manage difficult canals or previously failed treatments.
  
• Gum disease care ⁠— General dentists handle early treatment, while periodontists take advanced or surgical cases.
  
• Tooth removal ⁠— Simple extractions are performed by general dentists; impacted or surgical extractions are performed by oral surgeons.

If you’re unsure who should perform a procedure, ask your general dentist to explain the reason for treating or referring.

Orthodontics

Orthodontic care focuses on improving how your teeth and jaws work together, benefiting both your health and appearance. Treatment often begins with an evaluation around age seven to identify early bite issues, though most children do not need braces at that age.

Clear aligners, braces, retainers, and growth-guiding appliances are used to correct bite problems and support long-term function.

Periodontics

Periodontists treat advanced gum disease and protect the tissues that support your teeth. They handle cases that don’t improve after deep cleanings or that require gum surgery, bone grafting, or tissue repair.

Your dentist may refer you if gum pockets stay deep, bleeding persists, or bone loss becomes more severe.

Endodontics

Endodontists manage problems involving the tooth nerve and root tip, such as severe pain, lingering sensitivity, or recurring infections.

They use case-difficulty guidelines to determine when a tooth needs specialist care, which helps protect both your comfort and long-term success.

Prosthodontics

Prosthodontists restore or replace missing or damaged teeth, especially when aesthetics and function must work together. They plan complex reconstructions, full-arch rehabilitations, and implant-supported options.

Many general dentists complete simpler restorations, while prosthodontists take on the cases that need more advanced planning.

Oral Surgery

Oral and maxillofacial surgeons perform surgical procedures ranging from removing impacted teeth to repairing jaw or facial injuries. They also provide advanced anesthesia options for patients who need deeper sedation.

How Do Dentists Receive Their Degrees and Training?

Dentists receive either a DMD or a DDS degree, and these degrees are equivalent in terms of training, curriculum, and scope of practice.

After dental school, some dentists pursue multi-year residency programs to become specialists, while others expand their skills through continuing education. Cosmetic dentistry is not a recognized specialty, so additional training in that area is voluntary rather than required.

Licensing boards set rules for sedation and radiology, which means permits can vary by state. When you’re planning a procedure involving deep sedation, confirm your provider holds the appropriate state credentials.

To feel confident in your care, check whether your dentist has completed specialty residency training or holds certifications relevant to your treatment.

How Often Should You Visit a Dentist?

Your ideal schedule for dental visits depends on your level of risk, not a fixed timeline. Evidence from clinical trials shows that adults with a low risk of cavities or gum disease can safely follow personalized intervals, while those with a higher risk may need more frequent checkups.

Children follow similar principles, with visit timing adjusted based on their needs and habits. Imaging also follows a risk-based approach, so your dentist selects X-rays based on symptoms, age, and cavity risk.

Does Insurance Cover Dental Visits?

Insurance plans may still encourage twice-yearly visits, but your specific schedule should reflect your personal risk assessment. It’s always best to ask your dentist how your cavity and gum risk influences your visit schedule.

How to Prepare For Your Dental Appointment

It’s normal to feel a little nervous before a dental visit, so a small plan can help you feel prepared. Bringing the right information makes your appointment smoother and helps your dentist understand your concerns.

Here’s what to have ready:

• A current medication list for safe treatment planning.
  
• Your dental and medical history, so changes are easy to track.
  
• Insurance information or benefits details to estimate coverage early.
  
• A short symptom timeline describing when issues started and how they’ve changed.

If your symptoms worsen before your appointment, call the office so they can guide your next steps.
