Literature specific to impacted premolars is not extensive despite the fact that mandibular 2nd premolars alone account for 2.4% of dental impactions. The purpose of this paper is to describe the radical approach (extraction) of a transversally impacted 2nd premolar in the mandible through a lingual approach due to its peculiar position presuming it will contribute toward the literature regarding impacted mandible premolars.
