Tooth Colored Fillings also known as white fillings or composite resin are used to restore the natural appearance of teeth that have decayed or fractured. They look identical to natural teeth and are cost effective compared to gold fillings. Unlike other materials which take days to harden, composite resin takes only a few seconds to harden. Since the time they were introduced in the 1960’s, tooth colored fillings have undergone improvements in durability, aesthetics and material handling. They are chemically bonded to the teeth and do not require anesthesia in most cases. In cases of tooth decay numbing of the area may be required.
