Special thin laminates, called veneers, can often be used to correct discolored, worn down, cracked and chipped teeth. Veneers can also be used to close unsightly gaps between teeth. Stronger types of veneers made of porcelain, also called composite veneers, typically last longer because they are bonded to the tooth.
Another process called bonding can accomplish some of the same things, but it does not last as long. Material that looks much like the enamel on your teeth is used during a bonding procedure. The material is shaped to the tooth, and when it becomes hard it is polished.
In addition, dental contouring and reshaping can correct chipped, cracked, crooked, or even overlapping teeth. This procedure can alter the shape, length, or position of teeth.
