Based on current research, there is so much evidence to prove dental amalgam (containing mercury) to be harmful or have negative health outcomes. As a dental material, it is completely safe. It has been abandoned in most practices due to cosmetic reasons (unappealing colour) rather than its risk of harm. However, if you wish to replace your amalgam fillings with a resin or ceramic material, please let your dentist know and they can devise a treatment plan for you.
