Veneers are thin, custom-made shells crafted of tooth-colored materials designed to cover the front side of teeth. Veneers lasts longer than bonding and are made out of a harder material. Less tooth is removed than a traditional crown, and the don’t change color. They are an option for correcting stained, chipped, decayed or crooked teeth. Veneers are made by a dental technician, usually in a dental lab, working from a model provided by your dentist. Your dentist may recommend that you avoid some foods and beverages that may stain or discolor your veneers such as coffee, tea or red wine. Sometimes a veneer might chip or fracture. But for many people the results are more than worth it.
If you have any questions about veneers ask your dentist.
