Warning Signs Of A Tooth Abscess

Multiple types of tooth abscess can occur for a variety of reasons. As the name implies, a tooth abscess develops in or around one tooth. The abscess is a pus-filled pocket caused by infectious bacteria. Periodontal abscesses occur in the gums and at the sides of the root of teeth. Periapical abscesses form at the tip of a tooth's root. Periapical abscesses are usually the result of a cavity, prior dental work, or an injury. To treat a tooth abscess, dentists will drain the pus and remove the infection. The tooth can sometimes be saved through a root canal, but there are other cases where the teeth require pulling.
