Abscesses
A tooth abscess is a complication of tooth decay. It may also result from trauma to the tooth, such as when a tooth is broken or chipped. Openings in the tooth enamel allow bacteria to infect the center of the tooth (the pulp). Infection may spread out from the root of the tooth and to the bones supporting the tooth.
Infection results in a collection of pus (dead tissue, live and dead bacteria, white blood cells) and swelling of the tissues within the tooth. This causes a painful toothache. If the root of the tooth dies, the toothache may stop, unless an abscess develops.
Symptoms of an abscessed tooth:
- Toothache
- Severe, continuous pain
- Gnawing or throbbing pain
- Sharp or shooting pain
- Pain when chewing
- Sensitivity of the teeth to hot or cold
- Bitter taste in the mouth
- Breath odor
- Possible fever
- Swollen glands of the neck
- General discomfort, uneasiness, or ill feeling
- Swollen area of the upper or lower jaw — a very serious symptom
