Dentigerous cyst originates by the separation of the follicle from the crown of an unerupted tooth or a developing tooth bud. These cysts seldom associate with supernumerary teeth. The resorption of roots which are adjacent to a supernumerary tooth (mesiodens) or its cyst is a rare complication. The purpose of this article is to describe three rare cases of dentigerous cyst associated with supernumerary teeth and their complications and management.
