white fillings
White fillings are cosmetic dental prosthetics which are used to restore the natural structure and appearance of teeth. The dental filling material is called composite resin. It is a combination of different materials including glass ionomer, thermoplastics, silica, polymers, and quartz.
What makes composite resin unique is that it bonds with the tooth enamel. Unlike porcelain which needs cement to adhere to the tooth surface, composite resin can attach to the tooth. This process is called “dental bonding”.
In applying white fillings, the surface of the tooth needs to be etched with an acid gel first. This acid will roughen up the surface, making it easier for the filling to stick to the surface of the tooth. When cured with light, a chemical process allows the dental fillings to bond with the tooth surface. Once cured, the fillings become bonded to the tooth.
