A dental abscess is a collection of pus that can form inside the teeth, in the gums, or in the bone that holds the teeth in place.
It’s caused by a bacterial infection. An abscess at the end of a tooth is called a periapical abscess. An abscess in the gum is called a periodontal abscess.
Dental abscesses are often painful, but aren’t always. In either case, they should be looked at by a dentist.
It's important to get help as soon as possible, because abscesses don't go away on their own. They can sometimes spread to other parts of the body and make you ill.
