These photos are examples of Porcelain Laminate Veneers. As you can see, this treatment can make a dingy, unattractive smile become a beautiful one in a short time. Often these can be done with little or no alteration of the teeth. And they work on both top and bottom teeth.
In addition, laminates will solve other problems; such as spaces between teeth, chipped teeth, malpositioned or rotated teeth. They also can replace old bonding that is no longer attractive.
