Metachronous supernumerary teeth in a non-syndromic patient

This paper presents a case of metachronous supernumerary teeth in the mandibular premolar region, following previous removal of a supernumerary tooth and orthodontic treatment, in an adolescent patient following an interval of eight years. Individual or multiple supernumerary teeth can develop anywhere in the jaws, although it is unusual for sequential supernumerary teeth to develop in late adolescence and after orthodontic treatment, particularly in non-syndromic patients. The management of asymptomatic supernumerary teeth should fully consider the risks and benefits of surgical removal. Clinicians should remain aware of the possibility of subsequent supernumerary removal, and the presented case emphasises the importance of radiographic monitoring if subsequent orthodontic treatment is being considered following previous identification of supernumerary teeth.
