Evansville Dental Fillings DentistryAll of our fillings are tooth-colored, made of a resin material that forms a chemical bond to your tooth. It’s certainly more attractive than the old metal fillings, and provides a tighter seal to your tooth to prevent further decay. Our practice has been metal-free since 1995 to improve the aesthetics of your fillings and to avoid any potential mercury that could be in a metal filling.
