Viking tooth filing may have intimidated enemies

Long before grills and gold caps, Vikings used tooth decoration as a way to intimidate their enemies. Evidence can be seen in the intricate horizontal patterns filed into the teeth of Viking warriors found buried in Dorset.

David Score, of Oxford Archaeology, has been studying the bones and teeth of the Vikings found in a mass grave. "The purpose behind filed teeth remains unclear but as we know these men were warriors, it may have been to frighten opponents in battle or to show their status as a great fighter," he said.
