An endodontist is a dental health professional who specializes in treating damaged root canals in teeth.

Endodontists have a college degree and then attend 4 years of dental school. In addition, endodontists have 2 to 3 years of specialized graduate education in endodontic care.

Endodontists are licensed by the state in which they practice. While it's not mandatory, endodontists may acquire certification from the American Association of Endodontists' Board of Directors after passing a review and examination. To retain certification, endodontists are required to pass examinations every 10 years.
