title: Nonvital teeth and porcelain lanminate veneers--a contradiction?
abstract: Porcelain laminate veneers are widely accepted as the treatment of choice to noninvasively restore the esthetics and function of anterior teeth, provided there is a sufficient amount of tooth structure to support the reconstruction. However, there are certain esthetic limitations if the underlying tooth structure is discolored, which may occur in cases of nonvital roots. This article describes how to manage this esthetic challenge. Internal bleaching, tooth-colored internal buildups, and preparation guidelines are discussed via clinical case presentations.
