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.
Dental caries, or tooth decay, destroys tooth enamel. Recession of the gums away from the teeth, combined with an increased incidence of periodontal (gum) disease, can expose tooth roots to plaque, making them more sensitive and susceptible to tooth-root decay. This can lead to tooth loss, pain and more serious problems.
