Most filling treatments hold stable prices in the following ranges: 1  $50 to $150 for a single, silver amalgam filling. 2  $90 to $250 for a single, tooth-colored composite filling. 3  $250 to $4,500 for a single, cast-gold or porcelain filling.
Tooth colored fillings cost more than silver ones (tooth colored are more difficult and time consuming to do) and the fees vary by what part of the country you live in. I think $100 to $500 is a good rough estimate for what a filling could cost.
