Depends. Weren’t solid metal crowns often involved with mercury amalgams? Whenever mercury is involved with anything, I have an unshakeable suspicion that someone is being harmed somewhere. It’s a little like lead or a bloody body: maybe it’s perfectly innocent and there’s a reasonable explanation why you should not be worried by its presence… but don’t bet on it and call the police.

Hmm—as far as I know, the metal crowns that I have didn’t require any mercury amalgams.
