What is a Abscessed Tooth.
A dental abscess is a complication of tooth decay. Dental abscess an also result from tooth trauma such as a broken or chipped tooth. Opening in the tooth enamel allow bacteria to infect the center of the tooth. This infection can spread out from the root of the tooth and to the bones supporting the tooth if the tooth is not treated. The infection causes pus and swelling of tissues within the tooth, which will normally cause a painful toothache.
