A veneer is wafer-thin, custom-made shell that is bonded to a tooth to improve color and/or shape. They can also mask chips or cracks, if they are not serious dental health issues. Veneers are typically made from either porcelain or a resin composite. Porcelain veneers look more natural, and resist stains, but resin veneers can be made thinner, and require less removal of the surface of the tooth before being bonded. Veneers can transform a smile and restore self-confidence for those who have been hiding behind a smile they are not happy with.
