In clinical pediatric dentistry, there are not few occasions in which we encounter the cases with an anomaly in the number of teeth. The abnormality in the number of teeth directly affects the development of the dentition and occlusion. We experienced a very rare case of a patient with four supernumerary teeth in the maxillary anterior region.The patient was 7 year 3 month old boy when he was first examined. His chief complaint was an anomaly in the shape of the upper anterior teeth. Intraoral and radiographic examination revealed the presence of one erupted supernumerary tooth and three impacted supernumerary teeth in the maxillary anterior region. The tooth germs of the maxillary central incisors were located infraversion due to the presence of the supernumerary teeth. All the four supernumerary teeth were extracted under local anesthesia at the 7 years and 4 months of age. Two of the supernumerary teeth extracted were monocuspid types with the apex closed, and the other two teeth were rootless incisor types.Fenestration was rendered at the age of 8 years and 3 months, because the upper central incisors still had not erupted after extraction of the supernumerary teeth. After the upper central incisors erupted, the maxillary anterior teeth were aligned using a lingual arch with helical springs. The occlusal management with a multi-brackets appliance was then rendered because of a case of discrepancy, and this led to normal permanent occlusion.
