Amalgam fillings, also known as silver fillings, are a common and durable solution for restoring teeth affected by decay. Composed of a mixture of metals, including silver, tin, copper, and mercury, these fillings have been used for decades due to their strength and affordability. They are especially suited for restoring molars and teeth that endure heavy chewing forces. The procedure for placing an amalgam filling involves removing the decayed portion of the tooth, shaping the cavity, and placing the amalgam material, which hardens quickly to provide a strong restoration.
