Composite resin fillings, also known as "white" fillings, are a more modern way of restoring a tooth without the noticeable visability almost matching the color of your natural tooth. The composite filling is made up of quartz granules in a glue-like matrix that chemically bonds to the tooth structure, providing further support. This procedure is a more cosmetic way of resorting teeth and an alternative to the amalgam filling. Composite fillings are a more tooth-sparing preparation when compared with amalgam fillings, when removing decay and preparing for the filling, less tooth structure needs to be removed. Silver (amalgam) fillings are metal and have Mercury in them, and are more prone to leaking, resulting in decay beneath the filling and leading to root canals.
Composite fillings natural like color has its advantages and are used for many different things such as filling material for decay, repairing a chipped, broken, or worn tooth with out anyone ever knowing.
How it’s done
The procedure is done by first removing the decaying portion of the tooth. Once that is complete,
composite material can be stuck onto the teeth, the drilling is restricted only to that part of the tooth which is decayed. In the next step the surrounding healthy tooth is mildly etched and rendered porus. The treated tooth is then coated with a bonding liquid. Once the liquid has set, the composite resin material is applied to the tooth, trimmed to the desired shape, polished and adjusted to a natural appearance to fit your bite for maximum comfort.
