Transmigration of mandibular canines: report of six cases and review of the literature.

Six young adults were found to have transmigrated mandibular canines. One patient presented with two transmigrated canines. Of the seven impacted teeth, the left mandibular canines was involved in five instances and the right two. In all patients, the primary canine was present in the dental arch. A supernumerary tooth was disclosed on the panoramic radiograph of two patients. Five patients underwent surgical removal of the transmigrated tooth from an intraoral approach. One patient experienced transient postoperative paresthesia in the zone innervated by the mental nerve. When the transmigrated canine is accessible, and especially if it is symptomatic, removal of unerupted tooth is recommended. Otherwise, it should be left alone and kept under observation.
