Composites are a plastic-like material in the resin family used to fill teeth. The traditional composite resins are made up of a large amount of inorganic filler particles bound by an organic polymer matrix or mesh. The newer generation composites have superior properties which include higher strength, hardness, elasticity, abrasion resistance and high polishability to make the restoration appear lifelike. Uses include cosmetic, filling cavities, correcting size, color and shapes of teeth. They can be used in front as well as back teeth.
