Hyperdontia is more common in the permanent dentition than primary teeth. The rampancy of hyperdontia in the permanent dentition is reported to vary between 0.1 and 3.8 % and its rampancy in the primary dentition is found to be 0.3-0.8 %. A 20-year-old woman contacted the Faculty Practice Clinic at the Tehran University with concern regarding tooth caries. The panoramic radiography showed seven retained supernumerary teeth. Several clinical exams were then performed to rule out the presence of systemic pathology, and they all showed normal results. It is reported that the premolar region in the lower arch is the most common place for supernumerary teeth. Worldwide; many studies have reported the prevalence of supernumerary canines, which has been estimated from 0 to 1.5%. In our case occlusion was normal and no discrepancies observed.
