Silver fillings, also known as amalgam fillings, are made of metal alloy and are considered the best restorative solutions to cavities. However, the metal expands and contracts with the heat and cold placed in the mouth. This allows bacteria to enter a tooth once filled.
White fillings are often made in plastic or glass polymers. These cosmetic fillings allow Dr. Villalobos to fill a cavity with a substance that looks and feels just like your existing tooth structure. This restoration is created with a resin material and fits tightly into a tooth and prevents decay. Rather than a gray or silver material, the composite color is designed to match your tooth color.
