Possible problem: This generally does not signal a serious problem, unless the sensitivity remains for an extended period of time. It may be caused by minor decay, a loose filling or by minimal gum recession that exposes small areas of the root surface.
What to do: Try using toothpaste made for sensitive teeth and brush with a soft or extra-soft brush, using an up-and-down motion, never side-to-side, which wears away exposed root surfaces. If the issue persists, it’s time to see a dental health practitioner.
Possible problem: This jarring symptom may be caused by decay, a loose filling or a crack in the tooth. It’s also possible there is damage to the pulp tissue inside the tooth.
What to do: Get the matter evaluated by a dentist, who may refer you to an endodontist if there is pulp tissue damage. These specialists perform pulp-related procedures, such as root canals, which involve cleaning out the damaged pulp and filling and sealing the remaining space.
