How hard is it to get these fillings OUT of teeth? Are our only options to have teeth yanked that have mercury amalgams in them? I asked because I have like five molars left with DEEP fillings...The teeth seem to be cracked to the gumline too like from the fillings expanding and contracting I would guess. They are over twenty years old, what should people like me do about this Bryanna? I am scared they are going to be hard to get rid of...
