Dental Abscess
An abscess is a sac of fluid (pus). A dental abscess forms when a tooth or the tissue around it becomes infected with bacteria. The bacteria can enter through a cavity or a crack in a tooth. It can also infect the gum tissue or bone around a tooth. An untreated abscess can cause the loss of the tooth. It can even spread to other parts of the body and become life-threatening.

Symptoms of a dental abscess
Symptoms include:
-
Toothache, often severe
-
Tooth pain with hot, cold, or pressure
-
Pain in the gums, cheek, or jaw
-
Bad breath or bitter taste in the mouth
-
Trouble swallowing or opening the mouth
-
Fever
-
Swollen or enlarged neck glands
Diagnosing a dental abscess
The dentist will ask about your symptoms and check your teeth and gums. You will be told if you need any tests, such as dental X-rays.
Treating a dental abscess
Treatments for a dental abscess may include:
-
Antibiotic medicines. These treat the underlying infection.
-
Pain relievers. These help you feel more comfortable. Your healthcare provider may prescribe a medicine for you. Or you may use over-the-counter pain relievers, such as acetaminophen or ibuprofen.
-
Warm saltwater rinses. These can soothe mild pain and help clear away pus.
-
Root canal surgery. This may be done if needed to save the tooth. With a root canal, the infected part of the tooth is removed. A special substance is then used to fill the empty space in the tooth.
-
Draining the abscess. This may be done if needed. Cuts (incisions) are made to let the infected material drain from the tooth.
-
Removing the tooth. This is done in cases of severe infection that can’t be treated another way.
You may need to be admitted to a hospital if the infection is severe, has spread, or doesn’t respond to treatment.
When to get medical advice
Call your dentist right away if you have any of the following:
-
Fever of 100.4°F ( 38°C) or higher
-
More pain, redness, drainage, or swelling in the treated area
-
Face or jawbone swelling
-
Pain that can't be controlled with medicines
Preventing dental abscess
To prevent another abscess in the future, keep your teeth clean and healthy. Brush twice a day and floss at least once daily. See your dentist for regular exams and tooth cleanings. And stay away from sugary foods and drinks that can lead to tooth decay.
