There is a definite need for an esthetically acceptable conservative treatment to correct the disfiguring appearance of malformed and discolored teeth. This type of dental disturbance can introduce a grave psychologic effect on the patient. With the use of a specially shaded resin material, a thin plastic veneer, and an acid etch technique, an esthetic and functional restoration can be produced that will give the dentist and the patient consistently acceptable clinical results. The technique is essentially reversible and requires minimal or no tooth reduction, except where necessary for caries removal.
