Dental veneers are tooth-colored shells of porcelain or composite placed over the top of the facial surfaces of the teeth to correct worn tooth enamel, uneven alignment or spacing issues, discoloration, chips or cracks. Veneer placement requires the permanent alteration  or shaping  of the host tooth/teeth. (Minimal preparation veneers offer an alternative to traditional veneers in that they require less preparation of the natural teeth; however they too are more invasive than whitening.).
