Supernumerary teeth are relatively common in the general population, affecting the primary and the permanent dentition and have been reported in many genetic syndromes. They are classified according to form and shape. Seven different examples of hyperodontia are presented to highlight the numerical and morphological variation in dental abnormalities manifestations, empathising the importance of thorough clinical and radiological examination and of a correct therapeutic approach. The patients presented single or multiple hyperodontia, with particular interest for a 12 supernumerary teeth case. The clinical problems linked to supernumerary teeth were: impaction or ectopic eruption, crowding, possible root resorption of adjacent teeth. The therapeutical approach of supernumerary teeth varied on the position of the element in excess and on the complexity of the clinical case. In some cases the single extraction of the supernumerary tooth was indicated, while in other cases the extraction of the tooth was needed in addition to orthodontic treatment to gain sufficient space for the tooth with delayed eruption.
