What are veneers? Veneers are custom-fit, ultra-thin shells that are placed over the top of teeth in order to enhance appearance and cover up imperfections. Most often, veneers are made from dental porcelain, although they are also sometimes made from composite resin material. They are made in a variety of color shades so that it’s possible to match them with your natural tooth color. At Green Tree Dental, it’s our priority to give you a natural-looking smile over the long-term!
