A dental abscess is a pocket of fluid (pus) at the tip of a tooth root in your jawbone. It's caused by an infection that often starts with a crack or cavity in a tooth. Symptoms of a dental abscess may include mouth pain and swelling, fever, red gums, and bad taste in the mouth. The pain is often made worse by having hot or cold food or drinks, or biting on hard foods. The pain may spread from the tooth to your ear, or to the area of your jaw on the same side.
If the infection isn’t treated, more serious infections may spread to the face (facial cellulitis). Facial cellulitis is an infection of the skin and underlying soft tissues. This is a very serious condition. Once the infection and swelling starts, it can spread quickly. Symptoms of cellulitis may include red and swollen skin, fever, chills, and extreme tiredness (fatigue).
Follow these tips when caring for yourself at home:
Don't have hot and cold foods and drinks. Your tooth may be sensitive to changes in temperature. Don’t chew on the side of the infected tooth.
Put a cold pack on your jaw over the sore area. This can help reduce pain.
You may use over-the-counter medicine to ease pain, unless another medicine was prescribed. Talk with your healthcare provider before using acetaminophen or ibuprofen if you have chronic liver or kidney disease. Also talk with your provider if you’ve had a stomach ulcer or GI (gastrointestinal) bleeding.
Your provider will prescribe an antibiotic. Take it exactly as directed. Don’t miss any doses.
Follow up with your provider, dentist, or oral surgeon, as advised. Severe cases of cellulitis must be checked again in 24 hours. Once a tooth infection occurs, it will be a problem until the infection is drained. This is done through surgery or a root canal. Or you may need to have your tooth pulled.
