A veneer is essentially a 'false-nail' for a tooth , which is glued onto a tooth, in order to improve its appearance, or to change the shape of a tooth. Porcelain is the standard material used for veneers, because of its natural highly polished appearance and it being very hard wearing. Veneers can also be made out of composite, which is a white filling material, and these types of veneers are made in the surgery, on the same day, by the dentist, and glued onto the teeth. They, like porcelain, improve appearance and can change a tooth's shape.

In terms of top-end aesthetics and beauty, Porcelain veneers are still the best. Composite veneers tend to stain with time, but can be re-polished to some degree. Porcelain will retain its shine indefinitely. Composite veneers can be repaired easily if they chip or fracture, whereas porcelain ones cannot, and tend to need re-done if this happens. Composite veneers are also about half the price of porcelain ones.
