Also called Composite Fillings, Tooth-Coloured Fillings are made of durable plastic material mixed with small glass particles. Similar in colour and texture to natural teeth, these fillings are less noticeable and much more attractive than silver (amalgam) or gold fillings.
Teeth filled with composite material tend to be stronger as minimal tooth preparation (or drilling) is required and the composite material bonds more effectively to the surrounding tooth structure. Also this composite material has a thermal expansion coefficient very similar to natural teeth. This means that the filling will expand and contract, on drinking hot and cold drinks just as a natural tooth would.
