A case of supernumerary teeth in the premaxilla, maxillary cuspid, and mandibular premolar regions

A case of several developing supernumerary teeth is reported. A seven-year-old African-American boy presented with retained primary maxillary central incisors, two impacted mesiodens, and unerupted permanent maxillary central incisors. A dentigerous cyst was removed at the time of surgical removal of the mesiodens. Approximately fourteen months post-extraction, a new panoramic radiograph showed the presence of six previously unidentified developing and unerupted supernumerary teeth, one on each of the maxillary cuspid areas and two on the mandibular premolar regions bilaterally. Practitioners should be aware that supernumerary teeth may develop late. Thus, periodic reevaluation with appropriate radiographs is indicated, especially in patients who have presented with supernumerary teeth.
