An abscess is a collection of pus that forms in the body. It can be caused by a bacterial infection, and it can occur anywhere in the body, including the mouth. A dental abscess is an abscess that forms in the mouth, usually around the root of a tooth. Dental abscesses can be very painful, and they can lead to serious health problems if they are not treated.
Dentists can diagnose a dental abscess by examining the mouth and taking X-rays. The X-rays will show the abscess as a dark spot around the root of the tooth. Dentists may also use a probe to gently press on the abscess. If the abscess is painful, it is likely that it is infected.
