Understanding Dental Specialties
Most people see a general dentist for everything and never think twice about it — until a referral letter mentions an “endodontist” and they’re left wondering what just happened. Dentistry has several recognized specialties, each focused on a different part of oral health. Knowing who does what helps you understand referrals and find the right provider faster.
General dentistry
The general dentist is your primary point of contact and handles the vast majority of dental care: routine exams, cleanings, fillings, crowns, bridges, basic extractions, and preventive advice. Think of them as the family doctor of teeth. Many general dentists also perform procedures that overlap with specialties — simple root canals or clear-aligner treatment, for instance — depending on their training and interest. If you only ever see a general dentist, that’s completely normal and usually sufficient.
Orthodontics
An orthodontist specializes in the alignment of teeth and jaws. If you or your child needs braces, clear aligners, or correction of an overbite or crowding, this is the specialist involved. Orthodontists complete two to three additional years of training after dental school focused entirely on tooth movement and jaw development, which is why complex alignment cases are usually referred to them.
Endodontics
An endodontist focuses on the inside of the tooth — specifically the pulp and the tiny canals within the root. The procedure most people associate with them is the root canal. While many general dentists perform routine root canals, complicated cases (curved canals, re-treatment of a previous failure, or significant infection) are often sent to an endodontist, who has specialized tools and microscopes for the job.
Periodontics
A periodontist specializes in the gums and the bone that support your teeth. If you have gum disease that has progressed beyond what regular cleanings can manage, you may be referred here for deep cleaning, gum grafts, or treatment of bone loss. Periodontists also commonly place dental implants, since that involves the supporting bone.
Prosthodontics
A prosthodontist specializes in restoring and replacing teeth — dentures, bridges, crowns, veneers, and full-mouth reconstruction. For complex cases involving multiple missing teeth or a complete smile rebuild, a prosthodontist coordinates the aesthetics and the bite.
Oral and maxillofacial surgery
An oral surgeon handles surgical procedures: complicated extractions (such as impacted wisdom teeth), corrective jaw surgery, and the surgical placement of implants. They have extensive hospital-based training and can manage cases under sedation or general anesthesia.
Pediatric dentistry
A pediatric dentist focuses on children, from infancy through the teen years. Beyond child-sized equipment, they’re trained in the behavioral side of treating kids and managing the development of baby and adult teeth.
What this means for you
In practice, you’ll start with a general dentist, and they’ll refer you to a specialist only when a case calls for it. A referral isn’t a red flag — it’s usually a sign your dentist recognizes the limits of routine care and wants you to get the best result. Understanding the map of specialties simply means you’ll know what to expect, and which provider to look for, when that letter arrives.
