A porcelain veneer is a thin shell of porcelain that is bonded onto the front surface of a tooth so to improve its cosmetic appearance. A porcelain veneer can be an ideal way to make a cosmetic change for a tooth. Compared to dental bonding, porcelain veneers usually look more lifelike and they have the added benefit of resisting staining well. The chemical bond between porcelain and enamel creates a translucent, tooth-shaded unit with perfect natural aesthetics. Even a dentist can have difficulty telling veneered teeth from untreated ones.
