how much do fillings cost
Making the world better, one answer at a time. Although costs vary across the country and by dental office, the cost of typical metal filling ranges from approximately $75 to $145 per filling, whereas a composite resin fillings range from $150 to $300for a single surface white composite filling.. I wanted only composite fillings, and it cost $170 per filling. 2  I live in Northern Virginia where rent is relatively high. 3  My insurance only paid 80% of the mercury filling, that is $86 (of $105). 4  I guess $170.00 is right in the middle of the range of prices.
