The price of a filling depends on the material used. Single silver amalgam fillings (the most common and widely covered by insurance) cost anywhere between $50 to $150. Costs can range from $90 to $250 for composite (tooth-colored) fillings and from $250 to $4,500 for gold or porcelain.
Most dental insurance plans cover nearly all the expenses associated with fillings. Some plans may require a deductible or copay, or plan limitations may require additional out-of-pocket costs for fillings other than silver amalgam. If you are unsure, be sure to ask your dentist and/or your insurance company.
