Reshaping a mesiodens.

A mesiodens is a supernumerary tooth that is found in the midline of the maxilla. Fifteen percent erupt usually between the ages of 3 and 7. The standard treatment is extraction of the supernumerary to allow the permanent incisors to erupt properly. This case report describes an instance where the primary incisor was prematurely exfoliated due to the eruption of the mesiodens. Because of the favorable position of the mesiodens in the dental arch, it was decided to reshape the supernumerary to resemble a primary incisor. This was accomplished successfully, and the mesiodens is being monitored to assess any need to trim or add to the bonding material as the child grows.
