    well, it used to be lead and mercury, but those aren't used anymore because of health-risks, and because toothcoloured fillings look better.

    Silver and gold used to be in use too

    Note that liquid sodium or copper would be way too hot to put inside a tooth of a living human

    It is mostly mercury (about 50%) and silver (variable amount) with lesser amounts of other metals (copper, tin)

    E used to be true, I think it might not be allowed now.
