Metak Taste

So I have this caviti that is loose and everytime I touch it with my tongue it moves and it tastes like metal and then my whole mouth taste metally (if that's a word). What can I do about the taste?

If a filling is loose, immediate replacement is required.

Yes I understand but what do I do about the metal taste everytime I touch the filling.

If all metal fillings do generate metal taste, you can have composite filling, ceramic restorations as alternatives. However, other restorations probably cost you more than amalgam filiing does.
