Supernumerary teeth are defined as an excess in the number of teeth when compared to the normal dental formula. The prevalence of non-syndrome multiple supernumerary teeth are comparatively lesser in prevalence. The term 'supplemental' is however used when the teeth are extra but have the shape and size of normal teeth. The etiology of supernumerary or supplemental teeth is ambiguous, with different factors giving rise to different types of supernumeraries with combined etiological factors responsible for same. Supernumeraries generally cause problems of malocclusion of local nature like tipping of adjacent teeth, rotation, bodily displacement, delayed eruption or prevent eruption of tooth of normal series. Also, they may lead to esthetic disharmony and functional distortion. Since the supplemental teeth did not cause alterations in the eruption, position or integrity of the permanent dentition, a conservative approach was preferred.
