Perhaps a better term would be vapourize.
Mercury vaporizes off the surface of amalgam fillings 24/7. Mercury also infuses into the pulp chamber of the tooth and enters the blood stream. The interaction of 5 metals constantly keeps amalgam giving off mercury as well as copper and other corrosion products (16 of them).
Chewing food is one major way that mercury is released by a thousand percent.
It has several different routes in which it can enter the body.
All are devastating.
