Since the color of a composite resin filling can be customized, it is the most aesthetically pleasing option. However, it is more expensive and not as strong as an amalgam filling. Composite resin is ideal for repairing chipped or cracked teeth, filling in a tooth gap, correcting dental discoloration, protecting any exposed tooth root from gum recession, or changing the shape of teeth. Patients may also choose composite resin for cavity fillings as they are bonded to the teeth in layers and therefore require less drilling of the natural tooth.
