An endodontist is a dentist who specializes in treating the dental pulp and tissues surrounding the roots of teeth, which is known as the endodontium. Endodontists are experts in performing root canal treatments, which involve removing infected or damaged pulp from the inside of a tooth and sealing the root canal to prevent further damage or infection.
Endodontists receive advanced training in endodontic procedures, including diagnosing and treating tooth pain, performing root canal treatments, and managing complications associated with endodontic procedures. They also use specialized tools and techniques, such as dental microscopes and digital imaging, to provide accurate diagnoses and precise treatments.

If you have a tooth that is causing pain or discomfort, your general dentist may refer you to an endodontist for specialized treatment. Endodontists can help save damaged or infected teeth and prevent the need for extraction.
