The black filling material used in your teeth is amalgam. It has been used as a filling material for over a hundred years; it’s still one of the strongest materials available. However, these fillings can be highly unattractive and have a high mercury content. There are a number of other tooth-colored restorative materials currently available that can be used to replace old amalgams.
I have a number of black fillings, what can I have done to improve this?
