Until recently, dentists used an inexpensive silver and mercury amalgam to fill and seal cavities. Because silver fillings do not bond to a tooth, a chamber must be cut into the tooth that is larger than the exterior. This "undercut" keeps the filling in the tooth. Because a larger amount of the original tooth must be removed, these types of fillings often weaken teeth.
Recent innovations now allow us to replace old silver fillings with composite or porcelain fillings that are stronger, safer and more natural looking. Unlike silver fillings, composite fillings bond to the tooth and provide more protection from fracturing. The quartz-like material is layered into the tooth and hardened with highly intense visible light. The final surface is shaped and polished to match the tooth, making it virtually invisible to the naked eye. Say goodbye to "metal mouth" and hello to a beautiful new smile.
