Composite fillings or tooth colored fillings are a new age of resin that is reinforced with silica particles in a small spherical shape to allow for strength, density and the ability to highly polish the restoration which results in the resistance to staining. They look very natural and are virtually indistinguishable from the natural tooth. They are used in the anterior and posterior teeth and also to replace old unsightly amalgam or gray fillings. They will also provide years of service but do need to be replaced periodically.
Old amalgams need to be replaced when they become corrosive and their marginal seal breaks allowing bacteria to invade underneath causing recurrent carries. It is strongly recommended when they break or have extensive decay underneath.
