The American Dental Association still considers amalgam a "safe, affordable and durable material used to restore teeth." "Dental amalgam has been studied and reviewed extensively, and has established a record of safely and effectiveness."

Composite fillings are tooth colored restorations that bond to the tooth structure. This is a good option for patients that are looking for a more natural look.
