An exciting option in the field of cosmetic dentistry is the porcelain veneer. During this procedure, a thin shell of translucent porcelain is bonded to the front of the tooth, much like an artificial fingernail is attached. Candidates for this technology must have structurally sound teeth. The best results are usually obtained when multiple teeth are treated. Porcelain veneers are ideal for covering over discolored teeth, as well as reshaping teeth, closing gaps, and straightening some teeth. Veneers are usually completed in two office visits because they require that the tooth surface be prepared. Some patients are candidates for zero reduction veneers, where minimal tooth structure is removed in the preparation. This procedure is prevalent in the reality makeover shows.
