In the not too distant past, fillings were made of a metallic material called amalgam, and they were the best way to quickly repair small cavities and slightly damaged teeth. While these fillings are extremely strong and durable, their big issue is that they are a dark gray color, which makes them instantly stick out in any smile. Their metallic nature inevitably makes a tooth much more sensitive to hot and cold temperatures as well.
Today, fillings are still the ideal way to fix cavities, but they no longer use amalgam. Tooth-colored fillings are actually made of a composite resin material, and it comes in a variety of natural shades. This means we can choose the color that best matches a patient’s enamel, making the restoration blend in seamlessly. Even better, the resin enables us to place smaller and more conservative fillings, allowing us to better preserve a tooth and ensure its longevity.
