Gold Foil Restorations

Gold Foil Restorations

When decay erodes through the protective enamel covering of a tooth, it is then called a cavity because the rate of damage increases eight fold. Today there are an abundance of materials to select from in order to repair the damage caused by the germs. No material is as good as the original enamel, and no one material is best for all situations. One of these materials is called “gold foil”. Gold foil comes in tiny packets slightly larger than a pin head and is composed of a thin pure gold foil surrounding pure gold powder. These individual packets can be pressed into a hole left by the decay removal. However each packet compresses to a very thin layer; so to fill a tiny hole takes an enormous amount of time. The benefits are many. First gold is the only material that never tarnishes and in the mouth will last forever. Larger types of gold fillings are made to fit replicas of the tooth and then at a later date are transfered to and cemented into the tooth using a process called “inlay”. The weak link in the inlay process is in the cements. Cements can erode with time; however with gold foil restorations there is no cement, just gold. The gold is indestructable, and the tooth will never again need to be drilled.
