A mamelon (from French mamelon nipple) is one of three rounded protuberances which are present on the cutting edge of an incisor tooth when it first erupts through the gum. Mamelons are quickly worn away by use.Examine the newly emerged incisor teeth of a 6- or 7-year-old child. Three prominences or scallops are usually seen along the incisal edge. These prominences are developmental structures called mamelons but are ordinarily of no clinical importance.
