An abscessed tooth is an infection in or around the tooth. It can be very painful. If the infection isn't treated, it can spread and you can lose your tooth or have other health problems.
Damage to the tooth, an untreated cavity (tooth decay), or gum disease can cause an abscessed tooth.
If a cavity isn't treated, the inside of the tooth (called the pulp) can become infected. Bacteria can spread from the tooth to the tissue around it, creating an abscess.
Gum disease causes the gums to pull away from the teeth, leaving pockets. If food builds up in one of these pockets, bacteria can grow, and an abscess can form. Over time an abscess can cause the bone around the tooth to dissolve.
You may have:
Over time as the infection spreads, the bone in your jaw may start to dissolve. When this happens, you may feel less pain, but the infection will still be there. If you lose too much bone, your tooth will become loose and may have to be removed.
If you have a severe toothache, swelling of the gums or face, or drainage of pus, call your dentist right away. You may have an abscessed tooth. If it isn't treated, the infection could spread and become dangerous.
Your dentist will ask about your symptoms and look for swelling and other signs of infection in your mouth. He or she may tap on the tooth and apply heat or cold to the tooth.
Your dentist may also take dental X-rays.
An abscessed tooth needs treatment right away. Your dentist may:
You and your doctor can decide what's best for you.
To reduce pain and swelling, you can put an ice pack wrapped in a towel against your cheek. You can also try over-the-counter pain medicine, including acetaminophen (such as Tylenol) or ibuprofen (such as Advil or Motrin). Be safe with medicines. Read and follow all instructions on the label. If you smoke or use any kind of tobacco, try not to do so while your tooth is healing.
The best way to prevent an abscessed tooth is to take good care of your teeth and gums:
If you have a very dry mouth, you may be more at risk for deep cavities and tooth infections. To help prevent these, take frequent sips of water, chew sugarless gum, or suck on sugarless candy. Talk to your doctor about medicines that can help.
