What is the difference between crowns and veneers?

A crown is a covering used for a tooth that is badly shaped or colored, or to support a tooth with a large filling when there is not enough tooth structure left. Crowns can be made of porcelain fused to metal or just metal. Placing a crown onto a patient’s tooth requires that some of the natural tooth structure be removed. A veneer is a very thin overlay that is placed on the front of a tooth. It does not require removal of as much natural tooth structure. Veneers are best for restoring healthy and strong teeth that need to be adjusted for cosmetic purposes.
