Veneers - A veneer is a layer of tooth-coloring material that is applied to a tooth for aesthetically restoring localized or generalized defects or internal discolorations. Common indications are teeth with facial surfaces that are malformed, discolored, abraded or eroded by chemicals. Depending upon the type of material by which the veneer is processed it can last for a period of at least 7 to 8 years.
