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?
  1. Fever
  2. Pain when chewing
  3. Sensitivity of the teeth to hot or cold
  4. Bitter taste in the mouth
  5. Foul smell to the breath
  6. Swollen neck glands
  7. General discomfort, uneasiness, or ill feeling
  8. Redness and swelling of the gums
  9. Swollen area of the upper or lower jaw
  10. 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.

Abscessed Tooth

Baby bottle tooth decay

Baby bottle tooth decay (also called early childhood caries, nursing caries, and nursing bottle syndrome) occurs when a baby's teeth are in frequent contact with sugars from liquid carbohydrates, such as fruit juices, milk, formula, fruit juice diluted with water, sugar water or any other sweet drink. Human breast milk can cause tooth decay as well. As these liquids break down in the mouth into simple sugars and are allowed to sit in the mouth, bacteria start feeding on the sugars, causing tooth decay.

If left untreated, decayed teeth can cause pain and make it difficult to chew and eat. Also, baby teeth serve as "space savers" for adult teeth. If baby teeth are damaged or destroyed, they can't help guide permanent teeth into their proper position, possibly resulting in crowded or crooked permanent teeth. Badly decayed baby teeth could lead to an abscessed tooth, with the possibility of infection spreading elsewhere...
