What to do: See your dentist or endodontist to save the tooth with root canal treatment. Symptom: Constant and severe pain and pressure, swelling of gum and sensitivity to touch. Possible problem: A tooth may have become abscessed, causing an infection in the surrounding tissue and bone.
A root canal removes the diseased or infected part of the tooth, and it removes the nerve from a severely broken tooth, allowing the tooth to be saved. You may need a root canal if you have a severe toothache, usually along with swelling in your jaw around your tooth. When the pulp (the soft tissue inside the roots and center of a tooth) is damaged from a cracked tooth or other injury, or from a deep cavity, it can get infected.
