I think lead was used in dental amalgams but I don't know when it was phased out. But yeah, mercury too.

- bregma 7y agoThe word "amalgam" means a mixture of mercury with another metal. A lead amalgam would be too soft to use as a chewing surface (it would have a texture like chewing gum). Traditional dental amalgams were mixtures of silver or gold and mercury.
- praptak 7y agoYou are right, I probably misremembered what I've read.
