A composite resin is a tooth-colored plastic mixture filled with glass (silicon dioxide). Similar in color and texture to natural teeth, the fillings are less noticeable, and much more attractive, than other types of fillings. Composites are not only used for restoring decay, but are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth. These tooth-colored fillings were created as an alternative to traditional metal
dental fillings. Composite resin fillings are strong, durable, and make for a very natural looking smile.
Bonding and composite resin fillings do not bleach. If you are unhappy with the look, it is time to replace those. There are now many ways to restore teeth with materials that virtually disappear and blend with the natural color of your teeth.
Remember, only replace these fillings and bonding after whitening in order to match the new improved color of your own natural tooth.
