Late development of supernumerary teeth in the premolar region: a case report.

Supernumerary teeth are considered to be among the most significant dental anomalies affecting the primary and the early mixed dentitions. Early removal of such teeth is recommended if they impede the eruption of adjacent permanent teeth, appear inverted or rudimentary, or are associated with certain pathologic conditions. This report describes the appearance of late-developing supernumerary teeth in the premolar region in three quadrants.
