Reported increases of mesiodens within various ethnic groups are documented. For instance, supernumerary teeth in Japanese children are reported to be 0.05%, in Canadian pupils, 0.64%, and in Caucasian general populations between 0.1 and 3.8%. Higher percentages are reported in African and Asian populations as well.
The mesiodens interfere with eruption and cause other alignment problems with the existing teeth. Only a small portion of supernumerary teeth eventually erupts (approximately 25%) and the pattern of eruption is usually the first indication of a problem in the case of mesiodens. Because of the concern in eruption patterns, the dental professional usually orders radiographs to assess any problems that may be unseen clinically. Radiographs provide some assistance, but are often vague because of primary teeth obstruction.
Early intervention is suggested to prevent additional damage such as misalignment and delayed eruption of the permanent central incisors. Meighani and Pakdaman (2010) point out in a review of the literature that some practitioners prefer to wait to remove mesiodens until the root of the central and the lateral teeth are completely formed, so that damage to the permanent tooth is not an issue.
