Most dental care happens with a general dentist. But there are nine recognised dental specialties in the United States, each focused on a specific area of oral health. Understanding the difference helps you know when a referral makes sense — and when it does not.
What a General Dentist Handles
General dentists are your primary dental care providers. They are trained to diagnose and treat a wide range of conditions, including:
- Routine cleanings and check-ups
- Fillings for cavities
- Crowns and bridges
- Simple tooth extractions
- Teeth whitening and cosmetic bonding
- Basic root canals on front teeth
- Dentures and partial dentures
- Gum disease screening and basic treatment
For the vast majority of patients, a general dentist can handle everything without referrals. If your case is complex, they will refer you to the right specialist.
When You Might Need a Specialist
Orthodontist: Crooked teeth, bite problems, or teeth that need alignment correction. Most people are referred by their general dentist, but you can also see an orthodontist directly.
Oral Surgeon (Oral and Maxillofacial Surgeon): Wisdom tooth removal, dental implant placement, jaw surgery, complex extractions, or treating facial injuries.
Periodontist: Gum disease that has not responded to basic treatment, gum recession, or if you need gum grafts or advanced implant placement.
Endodontist: Complex root canals, especially on back teeth with multiple roots, or cases where a previous root canal has failed.
Prosthodontist: Complex tooth replacement cases involving multiple missing teeth, full-mouth reconstruction, or complicated implant-supported restorations.
Pediatric Dentist: Children, especially those with dental anxiety, special healthcare needs, or complex childhood dental issues.
Do You Need a Referral?
In most cases, you do not need a referral to see a dental specialist — you can book directly. However, if you have dental insurance, check your plan, as some HMO-style dental plans require a referral from your primary dentist before they will cover a specialist visit.
