Tooth abscess

Swollen gums and abscessed tooth, with detail of an abscessed tooth and a healthy tooth

An abscessed tooth is a tooth that has a pocket of pus in the tissue next to it. This often occurs because the inside (pulp) of a tooth is infected and the bacteria spread to the tissue underneath the tooth. An abscess usually causes throbbing pain in the tooth and red, swollen gums.
