Overview

An abscessed tooth is a tooth that has a pocket of pus in the tissues around it. Pus forms when the body tries to fight an infection caused by bacteria. If the pus cannot drain, it forms an abscess. An abscessed tooth can cause red, swollen gums and throbbing pain, especially when you chew. You may have a bad taste in your mouth and a fever, and your jaw may swell.

Damage to the tooth, untreated tooth decay, or gum disease can cause an abscessed tooth.

An abscessed tooth needs to be treated by a dental professional right away. If it is not treated, the infection could spread to other parts of your body. Your dentist will give you antibiotics to stop the infection. If antibiotics don't stop the infection, you may need other treatments.

How can you care for yourself at home?

• Brush and floss gently.
• Reduce pain and swelling in your face and jaw by putting ice or a cold pack on the outside of your cheek. Do this for 10 to 20 minutes at a time. Put a thin cloth between the ice and your skin.
• Avoid using tobacco products. Tobacco and nicotine slow your ability to heal.
• Take pain medicines exactly as directed.
  • If the doctor gave you a prescription medicine for pain, take it as prescribed.
  • If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine such as acetaminophen (Tylenol) or ibuprofen (Advil or Motrin). Be safe with medicines. Read and follow all instructions on the label.
• Take antibiotics as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
