For longer than you’d like to admit, you’ve had sensitivity in the first molar on the lower right side of your mouth. Drinking hot coffee or cold ice water is always a problem and you have to consciously avoid coming in contact with that area. And, for the past few weeks, the tenderness has increased and is a constant problem – your mouth is chronically sore. When you see Dr. Angelo Julovich, your dentist in Zionsville, he tells you that you have an oral infection and that a root canal will end the pain. In this post, he discusses what root canal therapy is and how it can benefit you.
