What is a dental abscess?

A dental abscess is a pocket of pus that forms due to a bacterial infection in or around the tooth. It can occur at the tip of the tooth’s root (periapical abscess) or in the gums (periodontal abscess). Dental abscesses are typically caused by untreated tooth decay, gum disease, or trauma to the tooth. The infection can spread to surrounding tissues and bones, leading to severe pain and swelling. Prompt treatment is necessary to prevent complications and preserve the tooth.
