Tooth Colored Restorations are fillings designed to match the color of your teeth. They may be used to restore a decayed tooth or repair a defect. Although they are often used on the front teeth (see Direct Resin Bonding) where a natural appearance is important, they are also commonly used on the back teeth. These restorations are prepared and placed in one dental visit. Your dentist will mix the composite material and match it to your tooth color for a natural appearance.
