What are advantages and disadvantages of composite resin filling?

Composite resin fillings are tooth colored and can be matched to the color of the rest of the teeth. They are bonded to the tooth structure chemically so there is no need for mechanical lock as the metal fillings do. Therefore they require less tooth structure reduction.
