For years, amalgam was the only option for filling teeth. Those who wanted natural-looking restorations had to opt for more expensive cosmetic treatments, such as a dental crown. However, the new composite resin enables dentists to cosmetically treat dental cavities without using invasive procedures.
Composite resin, a filling material designed for aesthetic dental restorations, is formulated to resemble the color of your natural tooth, and is often used for filling dental cavities or for dental bonding of the front teeth.
In its structure, composite resin consists of glass or quartz filler that’s added to a resin medium, producing a tooth-colored filling. The invention of composite resin offers a substitute to the amalgam dental fillings we've grown so accustomed to. This plastic and glass mixture contains no metal, and can be shaped to resemble a real tooth. Onlookers usually can't tell that a tooth has even been filled!
