Best answer
The element used in expensive dental fillings is Au, or gold.
Gold is used because it is inert and will not react with body fluids or cause an adverse reaction. Fillings can be either inlays or onlays. Inlays are smaller than onlays and are placed on the biting surface. Onlays are used when a larger surface of the tooth is missing.
