Dental Amalgam is a commonly used dental filling material that has been around for over 150 years. It is a mixture of mercury with at least one other metal. Amalgam has some advantages over other restorative materials, such as low cost, strength, durability, and bacteriostatic effects.
If an existing amalgam filling is in good condition, it is usually not necessary to remove the restoration. However, because today’s composites (white fillings) serve better than amalgam in nearly every circumstance, Dr. Caligiuri uses composite fillings for new direct restorations.
The American Dental Association Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
