A dental practitioner is a licensed healthcare professional who diagnoses, treats, and manages conditions affecting your teeth, gums, jaw, and surrounding oral structures. The term is broadly used to describe anyone who practices dentistry, though it most commonly refers to a general dentist. In the United States, general dentists serve as the primary oral health care provider for patients of all ages, coordinating everything from routine cleanings to complex treatment plans.
What a General Dentist Actually Does
A general dentist’s scope is far wider than most people realize. Beyond filling cavities and pulling teeth, they are trained and licensed to diagnose oral diseases, interpret X-rays, manage gum disease, perform root canals, place crowns, treat jaw joint disorders, and handle dental emergencies. They also screen for signs of systemic diseases that show up in the mouth, such as diabetes or autoimmune conditions, and adjust treatment plans accordingly.
General dentists can perform roughly 500 different procedures. That range covers preventive care like sealants and fluoride treatments, restorative work like fillings and bridges, surgical procedures like extractions, and cosmetic treatments like veneers. They also have prescriptive authority, meaning they can prescribe antibiotics, pain medications, and other drugs related to your oral health. When a case falls outside their expertise, they refer you to a specialist.
About 78% of dentists work in private dental offices. Another 12% are self-employed, running their own solo practices. The remainder work in government settings, physician offices, or outpatient care centers like community health clinics.
DDS vs. DMD: Two Degrees, Same Training
You may see dentists with either a DDS (Doctor of Dental Surgery) or DMD (Doctor of Medicine in Dentistry) after their name. Despite the different titles, these degrees are clinically identical. Both require the same admissions standards, the same accreditation requirements, and the same state licensure exams. The distinction is purely historical: DDS evolved from the surgical roots of dentistry, while DMD came from the medical side. The degree a dentist holds depends on which dental school they attended, not on any difference in training or skill.
12 Recognized Dental Specialties
After completing a general dental degree (typically four years of dental school following an undergraduate degree), some dentists pursue additional residency training to specialize. The National Commission on Recognition of Dental Specialties currently recognizes 12 specialties:
- Orthodontics: straightening teeth and correcting bite alignment
- Periodontics: treating gum disease and the tissues supporting your teeth
- Endodontics: root canal therapy and treating problems inside the tooth
- Oral and Maxillofacial Surgery: surgical treatment of the mouth, jaw, and face
- Pediatric Dentistry: oral care for infants through adolescents
- Dental Public Health: community-level prevention and disease control
- Oral and Maxillofacial Pathology: diagnosing diseases of the mouth and jaw
- Oral and Maxillofacial Radiology: interpreting diagnostic images of the mouth and face
- Oral Medicine: managing oral health in patients with complex medical conditions
- Orofacial Pain: diagnosing and treating pain in the jaw, mouth, face, and head
- Dental Anesthesiology: managing pain, anxiety, and sedation during dental procedures
- Prosthodontics: replacing missing teeth with dentures, implants, or other restorations
Specialists complete two to six additional years of training beyond dental school, depending on the field.
How Dentists Differ From Dental Hygienists
Dental hygienists focus on preventive care. They clean your teeth, take X-rays, apply fluoride, and educate you on oral hygiene habits. Hygienists can spot signs of potential problems, like gum inflammation or areas of decay, but they are not licensed to diagnose conditions or create treatment plans. When a hygienist notices something concerning during your cleaning, they flag it for the dentist, who then examines the area, makes a diagnosis, and decides on next steps.
Dentists hold full diagnostic and treatment authority. They can identify the cause of a problem, develop a personalized treatment plan, perform restorative and surgical procedures, prescribe medications, and manage complex cases over time. The hygienist and dentist work as a team, but the dentist carries legal responsibility for your overall oral health care.
Dental Therapists: A Newer Mid-Level Role
A growing number of states have introduced dental therapists, a mid-level practitioner role that sits between a hygienist and a dentist. Dental therapists are trained to provide preventive and routine restorative care: filling cavities, placing temporary crowns, performing simple extractions, applying sealants, and administering local anesthesia, among other procedures. They can perform around 60 procedures compared to a dentist’s 500.
Dental therapists work under the supervision of a licensed dentist, who remains responsible for diagnosis, risk assessment, and treatment planning. The role was designed to expand access to care in underserved communities where dentists are in short supply. As of early 2025, Alaska, Minnesota, and Washington have established dental therapy education programs, and numerous other states have passed legislation authorizing the role in various forms, whether statewide, on tribal lands, or in specific practice settings.
Education for dental therapists typically requires a three-year program resulting in a bachelor’s degree, as outlined by the Commission on Dental Accreditation. This is significantly less training than the eight-plus years (undergraduate degree plus dental school) required to become a dentist, which reflects the narrower scope of procedures they are authorized to perform.
