A case of bilateral 'double teeth' is described. The patient, aged 8 at initial presentation, was unhappy with the appearance of his two abnormally large upper central incisor teeth. Endodontic treatment was carried out on both teeth followed by surgical splitting and the removal of half of each so as to leave two reasonably-shaped central incisors. Comprehensive orthodontic treatment was then carried out to align the teeth and reduce the overjet, following which the central incisors exhibited no increased mobility or any periodontal problems.
