For patients with tooth imperfections, resin bonding provides an effective and affordable means of remedying tooth discolorations, gaps, and chips. However, porcelain veneers are superior in terms of strength, durability, and aesthetics. These factors may make porcelain veneers preferable to bonding for correcting tooth defects, particularly in the most visible teeth. In addition, porcelain veneers may be used to lengthen a tooth and to give the illusion that malpositioned teeth are straighter. The veneers are rigid shells that are firmly attached to outer tooth surfaces once the surfaces have been prepared to accept them. This preparation consists of removing a thin layer of enamel and etching the surface. Usually three office visits are required for the entire process.

P.S. Because porcelain veneers are individually sculpted, they are difficult to differentiate from natural teeth.
