Tooth-colored fillings are made from composite resins and provide good durability and fracture resistance for small- to mid-size fillings. They are versatile and can be easily used on both front and back teeth. Tooth-colored fillings are now used more often than amalgam (contains mercury) most likely due to aesthetics. Many people are focused on a white, bright smile and tend to want fillings that blend with the natural color of their teeth. For patients looking for a more natural look, tooth-colored composite resins are a good choice.
