What’s the difference between tooth-colored and silver fillings?

Silver fillings, also known as amalgam, have been around for decades. Made from a metal alloy, this type of filling expands and contracts with the heat and cold to stop decay but has become less common in modern dentistry. Tooth-colored fillings, also known as composites, are cosmetic fillings that look and feel just like your existing tooth structure. This restoration is created with a resin material and fits tightly into a tooth to prevent decay without being detectable.
