Supernumerary teeth may be defined as any tooth or tooth substance in excess of the usual configuration of twenty deciduous, and thirty-two permanent teeth. Although supernumerary teeth maybe found in any part of the mouth, they are located especially at the ends of tooth series. Unlike other supernumeraries, premolars are more likely to develop in the mandible than in the maxilla and usually resemble normal premolars in shape and size.
