Silver fillings known as amalgam have been around for decades. Made from a metal alloy, it was the best restoration for fillings. The metal expands and contracts with the heat and cold placed in the mouth. This allowed for little bacteria to enter a tooth once filled; keeping the tooth healthy and strong.
White fillings, also known as composites are often made of plastic or glass polymers. These cosmetic fillings allow us to fill a cavity with a substance that will look and feel just like your existing tooth structure. This restoration is created with a resin material and fits tightly into a tooth to prevent decay. Rather than a gray or silver material in your mouth, the composite color will match the tooth color.
