No sense of a tooth's characteristic translucency. Porcelain veneers, because they are glass-like, have a great advantage over other types of cosmetic dental bonding by the fact that they are translucent. When they are bonded onto a tooth's surface they mimic the light handling characteristics of enamel. Light striking a porcelain veneer will penetrate its thickness, and then subsequently be reflected back out once it has reached the opaque cement and tooth structure lying underneath the veneer. This translucency effect provides a sense of depth, and thus a very life-like appearance.
Porcelain veneers resist staining.
Cosmetic dental bonding materials utilized in the past had the shortcoming of being susceptible to staining and discoloring. This was especially a problem for those people who's teeth had excessive exposure to tea, coffee, red wine, or cigarette smoking. A significant advantage of porcelain veneers over other types of cosmetic dental bonding is related to the fact that a porcelain veneer's surface is just that, porcelain. Since porcelain is a ceramic, and therefore glass-like, its surface is extremely smooth and impervious. This means that the surface of a porcelain veneer will not pick up permanent stains.
