During archaeological excavation of St George's church, Canterbury, 269 skeletons ranging from early medieval to late nineteenth century were recovered. A medieval female aged ca. 23-28 years displayed an unusual dental anomaly, an odontome. Odontomes are infrequent in clinical dentistry. A search of the literature suggests thzt very few archaeological examples have been published and our specimen is the first excavated case reported from Britain. Archaeological material, if subject to radiographic examination, provides a unique source of information for the prevalence of odontomes from prehistoric to modern times.
