Teeth are capped or "crowned" for various reasons, often to restore form and function lost to decay or an accident, but also to restore a youthful vibrant appearance. It may be possible t change the appearance of the smile without compromising healthy tooth structure, by placing porcelain veneer restorations on the front teeth. Made from the same porcelain as caps or crowns, they are permanently bonded to the teeth to change color, alignment or form (or a combination of all three). It can be very amazing to see the results after a very short time that veneers can make.
