Dental veneers are tooth covers people get for cosmetic and dental-health reasons. The veneers are very thin and adhered to teeth to improve their shape and appearance, and to protect them. Patients with stained, gapped, misshapen, cracked, or chipped teeth often get veneers to improve their dental health and their smile, and the veneers look very natural, providing a natural-looking smile. These are the main benefits of veneers, but there are others too, and they all explain why veneers are so popular.
