Veneers are just that, a veneering layer applied most commonly to the fronts of your teeth. Veneers can also cover the entire tooth similar to a crown. Veneers are a good way to resurface damaged or worn teeth, as well as address various cosmetic concerns. Veneers frequently require some limited preparation to your teeth in order to correct teeth that are crooked or rotated. Veneers are also an excellent way to close spaces between teeth, and to cover badly discolored teeth.
