I don't think that all the mercury will leave the filling... Amalgams are 50%-70% mercury... The filling would shrink too much and fall out.

if you want to detox mercury you must remove your fillings.

The coriander can expell mercury from the brain but can also increase brain mercury if it is used too early, with fillings in and/or high body burden of toxic metals. It works sometimes, others get hurt by it. Never use it in early stages of detox.

Alpha Lipoic Acid is very cheap too and a good mercury chelator. If you take it on andy cutlers 3 hour schedule( read his book 'Amalgam Illness') there is little risk of long term or permanent worsening. If you take it too early and randomly you can make yourself much worse....
