Fillings. Fillings are used to repair a cavity in your tooth caused by decay. The most common type of filling is dental amalgam, made from a mixture of mercury and different metals. Dental amalgam fillings are often used on your back teeth as they are hard-wearing.
Fillings on the NHS can be made of: 1  amalgam (silver-coloured) â a mixture of metals including mercury, silver, tin, and copper. 2  composite (tooth-coloured) â powdered glass and ceramic added to a resin base; they're not as hard-wearing as amalgam fillings.
