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.
If the decay was very deep to the pulp of the tooth, this toothache response may indicate this tissue is no longer healthy. If this is the case, root canal treatment may be required. Referred pain. This is pain or sensitivity in other teeth besides the one that received the filling.
