Yes, they're a mercury/silver/tin/copper/zinc amalgam. There's been
a "scare" about it for years. Quite frankly, it seems there's little
evidence it's harmful*, as it's been in use for over 100 years, and
the amount of mercury entering the body from dental amalgam is very
small compared to that ingested in food.


*If mercury vapour is likely to be a threat, I suggest that to be
so you'd be at a temperature where mercury vapour would be the
least of your worries.
