Well, it's true -- mercury in an amalgam (normally with silver & tin) doesn't leach out. Most of the heavy metals that are dangerous by themselves can by alloyed or chelated to make them biologically safe.

This video from the International Academy of Oral Medicine and Toxicology - http://iaomt.org/videos/ - shows mercury vapour being released from a filling under such ordinary situations as drinking a hot drink, chewing, etc.

This episode of Skeptoid - http://skeptoid.com/episodes/4036 - discusses this very video and concludes that what we're actually seeing in the video is water vapour (since mercury vapour is much heavier than air, why is it rising in the video?).
