Dental Health: Abscessed Tooth
An abscessed tooth is a painful infection at the root of a tooth or between
the gum and a tooth. It's most commonly caused by severe tooth decay. Other
causes of tooth abscess are trauma to the tooth, such as when it is broken or
chipped, and gingivitis or gum disease.
These problems can cause openings in the tooth enamel, which allows bacteria
to infect the center of the tooth (called the pulp). The infection may also
spread from the root of the tooth to the bones supporting the tooth.
What are the symptoms of an abscessed tooth?
A toothache that is severe and continuous and results in gnawing or
throbbing pain or sharp or shooting pain are common symptoms of an abscessed
tooth. Other symptoms may include:

| What does an abscessed tooth look like? |
- Fever
- Pain when chewing
- Sensitivity of the teeth to hot or cold
- Bitter taste in the mouth
- Foul smell to the breath
- Swollen neck glands
- General discomfort, uneasiness, or ill feeling
- Redness and swelling of the gums
- Swollen area of the upper or lower jaw
- An open, draining sore on the side of the gum
If the root of the tooth dies as a result of infection, the toothache may
stop. However, this doesn't mean the infection has healed; the infection
remains active and continues to spread and destroy tissue. Therefore, if you
experience any of the above listed symptoms, it is important to see a dentist
even if the pain subsides.
How is an abscessed tooth diagnosed?
Your dentist will probe your teeth with a dental instrument. If you have an
abscessed tooth, you will feel pain when the tooth is tapped by your dentist's
probe. Your dentist will also ask you if your pain increases when you bite down
or when you close your mouth tightly. In addition, your dentist may suspect an
abscessed tooth because your gums may be swollen and red.
Your dentist may also take X-rays to look for erosion of the bone around the
abscess.
