A<unk>  is a localized collection of pus associated with a tooth. The most common type of<unk>  is a periapical<unk> , and the second most common is a periodontal<unk> . In a periapical<unk> , usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth. This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar<unk> . A<unk>  is a type of odontogenic infection, although commonly the latter term is applied to an infection which has spread outside the local region around the causative tooth.
