Temporary paresthesia of the lower lip: a complication of orthodontic treatment. A case report.

Abstract

Temporary mental paresthesia of the lower lip as a result of orthodontic treatment is extremely rare. Only two cases seem to have been reported earlier, a further case is described and discussed. The cause of this uncommon complication in the present case is obviously the close relationship between the distal root of the lower left second permanent molar and the mandibular canal.
