Ugly grey fillings are a thing of the past. Cavities today are filled with composite resins. These resins are constantly being improved and most are enhanced with microscopic Nano particles. Nano particles in combination with advanced dental resins result in very esthetic fillings that resist abrasion and polish to look like real enamel. When bonded in place, the restored tooth is stronger than teeth restored with silver/mercury amalgam. These restorations are also formulated with fluoride to help resist decay. These materials come in many colors to enhance your smile. Below you can see two teeth that have had old amalgam silver fillings replaced with newer composite resins.
