A supernumerary tooth is a dental abnormality, which, in some cases, causes disturbance in the eruption of permanent teeth. A seven-year-and-four-month-old female was diagnosed with eruption disturbance in mandibular canine eruption caused by a supernumerary tooth. At the age of eight years and six months, the supernumerary tooth was extracted and space maintenance by a lingual arch was started. Long-term follow-up and interproximal enamel reduction of the primary molar led to the mandibular canine eruption and prevented malalignment. This report highlights the importance of a comprehensive approach to managing supernumerary teeth through timely extraction and space maintenance to facilitate proper permanent tooth eruption.
多生牙是一种牙齿异常情况，在某些病例中会导致恒牙萌出紊乱。一名7岁4个月大的女性被诊断为因多生牙导致下颌尖牙萌出紊乱。8岁6个月时，拔除了多生牙，并开始使用舌弓进行间隙保持。对乳磨牙进行长期随访和邻面釉质磨除，促使下颌尖牙萌出并防止了牙列不齐。本报告强调了通过及时拔除和间隙保持来全面处理多生牙以促进恒牙正常萌出的重要性。
