The management of supernumerary teeth, especially mesiodens, consists of a wide range of treatment options. Constant monitoring of supernumerary teeth is mandatory to decide whether to retain it in case of its favourable positioning in the arch by reshaping or endodontically or orthodontically treating it. If its position is unfavourable, surgical removal may be followed. This case report consists of treating labially erupted mesiodens, resulting in early exfoliation of primary maxillary incisor in a five-year-old and modifying the mesiodens into primary incisor until its successor erupts.
