Odontogenic infection

Infection originating in a tooth

An odontogenic infection is an infection that originates within a tooth or in the closely surrounding tissues. The term is derived from odonto- and -genic. The most common causes for odontogenic infection to be established are dental caries, deep fillings, failed root canal treatments, periodontal disease, and pericoronitis. Odontogenic infection starts as localised infection and may remain localised to the region where it started, or spread into adjacent or distant areas.
