Supernumerary teeth may be single or multiple, unilateral or bilateral, and may occur in one or both jaws. The incidence of supernumerary is 1–3% and most occur in the maxillary anterior region, followed by maxillary molars, and the (maxillary/mandibular) premolars.1
Multiple supernumerary teeth are often found in syndromes such as cleidocranial dyostosis, Gardner's syndrome and cleft lip and palate. However, the occurrence of a supernumerary tooth is rare in the incisor region of the mandible. The first case of bilateral supernumerary mandibular incisors was reported by Tanaka et al in Japan.2 Bodin et al examined 21,609 patients and found 422 supernumerary teeth, of which only four were seen in the mandibular incisor region.3 Locht studied the radiographs of 704 children and found no cases of supernumerary teeth in the anterior part of the mandible.4
