Actually it can corrode on the tooth side and not on the visible side
with the protective oxidized layer so going to the dentist isn't
necessarily any help, unless you get all your fillings replaced every
5 years.

I have to warn you, when Dr. Steve M tried to argue that people didn't
have to worry about amalgam (elemental) Hg on SMD because most people
were
nose breathers he was nearly tarred and feathered!

Actually virtually no research has been done to determine how much
Methyl Hg can result from amalgam fillings. This has been discussed
before on SMD. Why? turns out its really hard to measure amalgam
derived methyl Hg absorption into tissue but many common oral bacteria
including S mutans can convert the Hg from crushed amalgam in test
tube. Also significant levels of amalgam derived methyl Hg have been
measured in an extremely small study on crowns and veneers. Sooooo,
contrary to what you have been led to believe (probably by the ADA) a
corroding filling packed with bacteria on top CAN be a large source of
Hg. it can also be methylated in the gut. (You might want to see Bernie
Windhams page were he actually claims amalgam is also on average the
largest source of organic Hg. That's right you heard correct!)

Of course all things being equal i would much prefer a filling leaking
a little more elemental Hg than one corroding with methylizing
bacteria around the filling! Too bad you can't brush into between
the filling and the tooth!
