Introduction: Supernumerary teeth are additional teeth besides the normal series causing interference to the developing permanent incisors and resulting in poor dental and facial esthetics. Many complications can be associated with these supernumerary teeth such as impaction, delayed eruption or ectopic eruption of adjacent teeth, crowding or the development of median diastema. Aim: The aim of this work is to present two cases of Supernumerary teeth treated in the dental department of Farhat Hached teaching Hospital in Sousse. Résultats et discussion: Two male patients aged 12 and 8 respectively were referred to the dental departement of Farhat Hached Hospital due to swelling in their maxilla and delayed eruption of central incisors. The intra-oral examination showed the absence of the left central incisor for the first patient and an ectopic erupted one in the second patient. Upon radiological examination, impacted supernumerary teeth with partial root development were found. Both supernumerary teeth in both patients impeded the eruption of their central incisors and were surgically removed. The prevalence of supernumerary teeth in Caucasians has been reported to be between 1% and 3% which is slightly higher than the Asian populations. Single tooth hyperdontia was found in approximately 76% to 86% of the cases. Although supernumerary teeth could erupt normally, they may remain impacted. The most common complication of supernumerary teeth is maxillary incisors eruption failure. Early diagnosis and treatment of patients with supernumerary teeth may prevent or minimize complications. The treatment options depend on the supernumerary teeth type and position. Orthodontic treatment is often necessary to achieve optimum occlusal and aesthetic results. The disadvantage of the combined surgical/orthodontic therapy is that it requires a longer treatment period and some complication including ankylosis, non-vital pulps and root resorptions.
