Dental amalgam fillings have been used for over 150 years. Like composite fillings, amalgam fillings are used to restore a tooth after decay. Amalgam restorations last almost double the time of composite fillings–between 10 and 12 years. In addition, they provide you with a low cost, strong and durable filling option.
Both Amalgam and Composite Fillings are considered safe and effective for tooth restorations.
