Abstract

Supernumerary teeth are teeth added to the normal complement of teeth. They are most often found in the maxillary anterior region. Most supernumerary teeth in the maxillary anterior region have complications, such as impaction or malposition of permanent teeth, formation of diastema, cysts, and eruption into the nasal cavity or into the oral cavity. These complications have influence on deciding the treatment and its prognosis is depends on how these complications are treated. In clinical studies, it has been found that the removal of supernumerary teeth before the age of 5 years resulted in significant fewer eruption problems of the permanent tooth compared to removal at 7 years of age or later. However, such an early removal may leads to serious consequences of tooth development and behavioral management of patients. Therefore clinicians must consider complications of supernumerary tooth when deciding the time of removal. These cases report five-type of complication associated with supernumerary tooth such as diastema, delayed eruption, external root resorption, migration into nasal cavity and cyst formation.
