You don’t have to put up with unsightly metal fillings any more with the development and use of natural-colored fillings, which are undetectable to the eye. Properly restored teeth with these types of fillings function and wear normally, appearing indistinguishable from natural teeth. And scientific studies and clinical experience have validated their use as safe and predictable. The most commonly used materials consist of resin plastic (methacrylate) and fillers made of silica, a form of glass. The fillers are what give the tooth composite wear resistance and translucency (see through properties).
