Long used in anterior teeth, composite fillings have advanced over the years. With strides in dental technology and materials, composite fillings are now more durable and stronger than they have ever been. Many people are choosing composites over amalgam for a variety of reasons. Metal allergies have long been a problem for some with silver fillings. Though rare, for those who have it, composite fillings offer a relieving alternative in cosmetic dentistry.
When you open your mouth wide, such as for singing or a hearty belly laugh, even your back teeth can be seen. Composite fillings hide the fact that your molars have seen better days. Composites make it possible for even the biggest smile to look completely natural with no glint of metal.
What is a Composite Resin?
Composite resins are created from a mixture of plastic and glass or ceramic. After the cavity is cleaned out and made ready for filling, the putty-like substance is placed in the cavity and molded to the confines of the tooth. Once set, it is trimmed, smoothed and polished.
Some resins require a special light to cure them. The light causes a chemical reaction in the resin which causes it to harden. The tooth-colored material comes in a wide variety of shades to match any color of teeth. When finished, the composite filling looks and feels like the natural tooth.
Another reason composite fillings are preferred has to do with tooth structure. Amalgam fillings require additional healthy tooth material to be lost in order to prep the tooth so that the filing will not fall out. Amalgam fillings also expand and contract over time. Composite fillings do not have these issues. A bonding agent is used to adhere the composite to the tooth. No extra tooth structure needs to be damaged to place a composite filling.
