Composite fillings are also known as Tooth Colored Fillings since the material used can be closely matched to the tooth. Composite Fillings can be used to fix gaps between teeth, restore broken, decayed teeth, or worn teeth. Composite fillings are available in a wide variety of shades that blend into the surrounding tooth making them virtually unnoticeable. They are bonded to the teeth which make composites more conservative because less tooth structure is removed.
