Treating a cavity is usually fairly simple, but you still have options in the filling you choose. While metal amalgam has been a popular material for quite some time, more and more patients are choosing acrylic-based composite resin, which blends in discreetly with the tooth it repairs. Known as tooth-colored fillings, composite resin restorations are often the best option for restoring a mild to moderate cavity. Not only is the filling unnoticeable, the material also performs better in many respects compared to its metal counterpart.
How does the filling blend in with my tooth?
As a mixture of metals, the color of dental amalgam is dictated by the color of its components. As a blend of fine acrylic and quartz-like particles, composite resin can be tinted to match the color and shade of any healthy tooth. Instead of clashing with your tooth’s appearance, a resin filling will appear as part of your tooth’s natural structure.
What makes tooth-colored fillings more effective?
An attractive appearance is only one of the many benefits of tooth-colored fillings. Composite resin can also be bonded to a tooth’s surface more effectively than metal amalgam, so it can better repel oral bacteria from infecting the tooth again. Bonding the resin also helps improve the tooth’s structural integrity by holding its structure together.
What if I already have a metal filling?
Even if you’ve already had to treat a cavity with a metal filling, we can upgrade the older restoration with a tooth-colored replacement. Besides being a better option for your smile’s appearance, a resin filling will also produce less friction against opposing teeth, and replacing your metal one can benefit your overall oral health as well as the tooth in question.
