The majority of supernumerary teeth seen in primary dentition are of a supplemental type and usually unilateral. Presence of supernumerary teeth has been noted in primary dentition but bilateral occurrence is rare. A 4-year-old girl with the symptoms of decayed teeth was brought to the dental clinic. Medical and family history was not significant. The patient had normal development and build for her age and sex. On clinical examination, an extra tooth was noted on either side of the maxillary quadrants, which mimicked, in shape and size, the lateral incisors more than they did the central incisors. These supplemental teeth were noted bilaterally mesial to the primary canines. Dental caries was noted in relation to 51, 52, 61 and 62 (figures 1–3). Intraoral periapical radiograph showed dental caries involving the pulp of 51 and 52 (figure 4). An orthopantomogram was taken to rule out other additional supernumerary teeth in the arches (figure 5). Bilateral supernumerary teeth mesial to primary canine was diagnosed based on the morphology of the primary lateral incisor crown, which was smaller in all dimensions compared to the supplemental; also, the roots of the supernumerary teeth appeared to be longer than those of the lateral incisors.
