If the discomfort lasts only moments, sensitivity to hot and cold foods generally does not signal a problem. The sensitivity may be caused by a loose filling or by minimal gum recession which exposes small areas of the root surface.

Try using toothpastes made for sensitive teeth. Brush up and down with a soft brush; brushing sideways wears away exposed root surfaces. If this is unsuccessful, see your dentist.

Dental work may inflame the pulp, inside the tooth, causing temporary sensitivity.

Wait four to six weeks. If the pain persists or worsens, see your dentist.

There are several possible causes of this type of pain: decay, a loose filling, or a crack in the tooth. There may be damage to the pulp tissue inside the tooth.

See a dentist for evaluation. If the problem is a cracked tooth, your dentist may send you to an endodontist. Cracked tooth pain comes from damage to the inner soft tissue of the tooth, the pulp. Endodontists are dentists who specialize in pulp-related procedures. Endodontic treatment, also known as root canal treatment, can relieve that pain.

This probably means the pulp has been damaged by deep decay or physical trauma.

See Drs. Hall or Gailey to save the tooth with root canal treatment.

A tooth may have become abscessed, causing the surrounding bone to become infected.

See Drs. Hall or Gailey for evaluation and treatment to relieve the pain and save the tooth. Take over-the-counter analgesics until you see the endodontist.

The pain of a sinus headache is often felt in the face and teeth. Grinding of teeth, a condition known as bruxism, can also cause this type of ache.

For sinus headache, try over-the-counter analgesics or sinus medicine. For bruxism, consult your dentist. If pain is severe and chronic, see your physician or endodontist for evaluation.

Sometimes pulp-damaged teeth cause pain in other parts of the head and neck, but other dental or medical problems may be responsible.

See Drs. Hall or Gailey for evaluation. If the problem is not related to the tooth, your endodontist will refer you to an appropriate dental specialist or a physician.
