We are not mercury-free practice. Many people want to remove/replace silver/mercury fillings in their mouths from years past to something better fitting their bright smiles.

Composite restorations are not only esthetically pleasing but also very strong thanks to new bonding technologies. You can have your silver fillings replaced with tooth-colored restorations (Composite).
