“Silver stars” are another name we use for silver fillings. It is made of dental amalgam. Dental amalgam is a mixture of mercury and an alloy of silver, tin and copper. Mercury is used to bind the metals together and provide a strong, hard durable filling material. Mercury in dental amalgam is not poisonous. When mercury is combined with other materials in dental amalgam, its chemical nature is changed making it harmless.
