Patients go to an endodontist when they experience significant, unexplained dental pain or have other complicated dental problems. An endodontist's job is to get to the root of the problem and find the best solution to return the tooth to a healthy and natural state. Most people don't know the difference between a dentist and an endodontist, but the American Association of Endodontists clarifies that by explaining that endodontists specialize in “saving teeth.” Endodontists focus on the inside of the tooth and think about endodontic procedures (or don't if it makes you uncomfortable). They focus on dental pulp, as well as soft tissue and nerves.
Unlike dentists, they don't do the outside work, such as filing or biannual cleanings.
