Treatment of triple tooth: report of case

A case of a young girl with a triple primary tooth that retarded normal development of the maxillary left lateral incisor is described. The primary tooth was extracted to encourage normal development of the permanent tooth. Subsequent examination of the extracted triple tooth suggests that it was composed of the primary left lateral incisor fused either to a geminated central incisor or to a fused central incisor and supernumerary tooth.
