Seek dental care: Seek dental care ASAP. Have the dentist radiograph the area or areas if the last full mouth series of x-rays was taken over three to five years ago. If possible, have your dentist e-mail any pertinent x-rays to the dentist for a point of comparison. This should help the dentist ascertain your problem or problems.

Needs Evaluation: A dentist needs to evaluate the tooth in question. A fracture, a recurrent abscess, or even periodontal problems may be contributing to the pain. One tooth should not make all your teeth sensitive, so there may be two issues.

See a dentist ASAP: A tooth infection won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your body. Dentist will treat a tooth abscess by treating the cause and getting rid of the infection. Do not delay. Good luck.
