Composite resin is a filling material designed for aesthetic dental restorations. Composite fillings resemble the color of your natural tooth and are made in a wide range of tooth colors allowing near invisible restorations of teeth. Composite fillings require only the diseased part of the tooth to be removed. The filling is actually bonded to the tooth and restores the tooth’s natural strength allowing it to withstand pressure from chewing rather well.
Mercury “silver” fillings are viewed by some as being toxic. Amalgam fillings require a larger section of the tooth to be removed for retention to hold the filling. As the amalgam filling is exposed to cold and hot temperatures it causes the filling to expand and contract causing teeth to become weak and crack. Since broken teeth are expensive to restore, composites can save a lot of expense over the long run.
