The discomfort [pain] caused by changes in the health of teeth. The best advice is to go and visit a dentist as soon as possible.
The teeth and the tooth attachments may give rise to painful symptoms as a result of decay, abscess, periodontal (gum) disease or eruption problems. The pain may vary from an intermittent or fleeting sensitivity to hot and cold that may indicate the early onset of decay to the most dreadful acute throbbing pain caused by advanced decay and a dental abscess. In this latter case it may be impossible even to touch the teeth together and eating may be difficult.
