A root canal in your tooth can become infected due to a cavity or fracture that allows in bacteria. When a root canal becomes infected it can die. At this point you will begin to feel pain and pressure in and around the infected tooth. According to Dr. Abraham Katz of Herndon, VA this is your first sign that you will need one of the most common procedures in general dentistry, root canal therapy. Without treatment the infection spreads and could lead to tooth loss.
