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.
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.
See a dentist if you have toothache that lasts more than 2 days. There are things you can do to ease it while you wait for an appointment.
