Peg lateral incisors describes a condition where the second tooth on either side of the upper front teeth does not develop correctly and is small, often pointed, and looks like a cone. Sometimes, the permanent adult teeth do not develop at all, leaving only the baby teeth or primary teeth in place. While some people refer to these teeth as peg laterals, a true peg lateral incisor is a term reserved for the under-developed adult permanent tooth that erupts after the baby tooth has been lost.
Because upper lateral incisors play such an important role in the appearance of your smile, peg lateral incisors receive a great deal of attention. A prosthodontist can determine the best treatment for any misshapen teeth and is uniquely qualified to restore a peg lateral incisor to give you an esthetically pleasing smile.
Commonly, these can be treated using composite resins, porcelain veneers, or crowns.
