This can be seen in both deciduous and permanent dentition. Depending on the stage of development of teeth at the time of union, fusion may be either complete or incomplete. The prevalence of tooth fusion in the primary dentition is 0.5%–2.5% and 0.1% in permanent dentition. The exact etiology is not known, but it is thought that some physical forces or pressures cause the contact of developing teeth. The fused teeth can lead to various problems. Here, we discuss a case of a fusion in primary central incisor with supernumerary tooth in a 7-year-old male child. ER -
