Tooth Abscess

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 pulp of the tooth dies, the toothache may stop, unless an abscess develops. This is especially true if the infection remains active and continues to spread and destroy tissue.

Symptoms

The main symptom is a severe toothache. The pain is continuous and may be described as gnawing, sharp, shooting, or throbbing.

Other symptoms may include:

Bitter taste in the mouth

Breath odor

General discomfort, uneasiness, or ill feeling

Fever

Pain when chewing

Sensitivity of the teeth to hot or cold

Swollen glands of the neck

Swollen area of the upper or lower jaw -- a very serious symptom

Treatment

Prompt treatment usually cures the infection. The tooth can usually be saved in many cases.

Call your dentist if you have a persistent, throbbing toothache. 1300SMILES offers an emergency and afterhours service if needed.  Prompt treatment of dental caries reduces the risk of tooth abscess. Traumatized teeth should be examined promptly by the dentist.

The goals of treatment are to cure the infection, save the tooth, and prevent complications.

Antibiotics may be given to fight the infection. Warm salt-water rinses may be soothing. Over-the-counter pain relievers may relieve the toothache and fever.

Do NOT place aspirin directly over the tooth or gums, because this increases irritation of the tissues and can result in mouth ulcers. 

A root canal may be recommended in an attempt to save the tooth.

If there is a severe infection, the tooth may be removed or surgery may be needed to drain the abscess. Some people may need to be admitted to the hospital.

Untreated abscesses may get worse and can lead to life-threatening complications.

Prompt treatment usually cures the infection. The tooth can usually be saved in many cases.
