This is a case report of multiple supernumerary teeth of identical twins with 5 years of follow-up. The occurrence of supernumerary teeth in twins is an unusual event. This case report describes 7-year-old Taiwanese twin brothers who both presented with multiple supernumerary teeth in the premaxillary and mandibular premolar regions. The supernumerary premolars developed much later than the premaxillary supernumerary teeth in these twins. The supernumerary premolars caused impaction of the mandibular first premolars. Cases with multiple supernumerary teeth in twins are unusual, especially of supernumerary teeth affecting both the premaxilla and mandible. Such cases imply that heredity plays a role in the occurrence of supernumerary teeth.
