Dental amalgam fillings are made from a compound of metals and having a filling is among the most common dental procedures. These fillings have been used as the treatment of choice to fix dental cavities and tooth decay for more than 150 years. It is estimated that, across the world, about 1 billion amalgam fillings are placed annually.
If you opt for an amalgam filling, your dentist will remove the decayed area of your tooth and shape the cavity ready to be filled. Your dentist will mix the powdered metal alloy with the liquid mercury, creating an easy-to-work-with amalgam putty. This is then placed in the cavity and shaped as necessary, before quickly hardening to a strong, durable filling.
