Are thin, custom-made shells that are designed to cover the front side of teeth. They are used to close spaces between teeth and treat teeth that are permanently stained, poorly shaped, or slightly crooked. Veneers can also be placed over teeth which will not whiten effectively. Veneers are facades of teeth that can be made of ideal shape and color to improve the clients smile. The process is usually irreversible and requires removing a small amount of enamel to accommodate the thickness of the shell. The procedure may take two or more appointments.
