lurch:
hope you\'ve gotten that tooth fixed up. it may seem to be holding out w epoxy putty but a nice new case of dental caries could be building up under the impromptu restoration due to microleakage and entry of bacteria and you WOULDNT EVEN SEE IT cos of the whitestuff! more hassle than its worth..
amalgam resto isnt all that bad. so if mercury is nasty stuff why do we use mercury? its an amalgam! we need the mercury as a solvent for the copper and tin and silver to form a soft, squishy plastic alloy so we can pack it into the cavity; the silver and copper and tin components dont exactly come soft or mixed in their \'elemental\' cast state. and as the amalgam condenses in the cavity the mercury settles to the top of the amalgam and is scraped off as the dentist carves some shape into the restoration. removing the mercury-heavy amalgam portion. sure, leaching may occur, but its not much more than what you get naturally from your usual diet. the ones who are more in danger are the dentists, and thats only if they like to buy their mercury separately and mix without gloves!
