A root canal is a treatment used to save teeth that have become infected or are extremely damaged. There must still be enough tooth left to restore or another treatment such as an implant may be indicated. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed.

Without treatment, the tissue surrounding the tooth will become infected and abscesses may form. Tooth pain upon chewing, prolonged sensitivity to hot and cold temperatures, or swelling and tenderness in nearby gums may indicate the need for treatment.
