When teeth have cavities or are broken, in some cases they can be restored with a simple filling. Fillings have limitations and in order to be successful a certain amount of strong tooth structure is needed to support the filling. There are two types of filling materials. One type is a tooth-colored resin material that bonds to the tooth. The other type is a mercury filling that is silver in color. Many dentists today will not use or recommend the mercury based fillings. You can raise any concerns you have before the filling is placed in your tooth.
