The most common reason for having a root canal treatment is when the inside part of the tooth is dead or dying.
Sometimes this process can be extremely painful and people are grateful for the relief offered by the procedure. At other times the tooth can die without warning and infection can spread through the bone around tooth and you don’t even know about it until an x-ray is taken or the infection spreads to the point where it is noticed.
In either situation, root canal treatment can help you keep your damaged tooth.
