Composite resin is a versatile white material used in dentistry to repair teeth. It is quick, inexpensive, polishes to a smooth lustre and looks like a normal tooth. It is not the strongest material, yet it will achieve good results for around 5 - 7 years. (For more long term options see Crowns and Porcelain Veneers). As it bonds extremely well to enamel, composite resin is a good material to add new shape to teeth without having to remove or reshape the natural tooth.
