Bimaxillary hyperhypodontia (BHH) is a very rare numeric anomaly with a prevalence of 0.002% to 3.1% described by the presence of a supernumerary tooth in the premaxilla region and a missing mandibular incisor tooth. This case highlights the multidisciplinary management of a child presenting with BHH who complies with the recommended protocol by surgically removing the supernumerary tooth and then proceeding with orthodontic treatment for function and aesthetics. A 9-year-old healthy Malay boy presented with a fully erupted tooth 21, a labially palpable bulge of unerupted tooth 11, a missing tooth 32, and a tendency for an anterior and posterior crossbite. The radiographs showed an inverted, unerupted, conical-shaped supernumerary tooth overlapping the unerupted tooth 11 and hypodontia of tooth 32. The management was surgical removal of the supernumerary tooth and the placement of an upper removable appliance with a palatal expansion screw followed by comprehensive fixed orthodontics.
