Austin says he doesn't use the vega because he is dubious about it's merits and considers it more of a diagnastic tool. He says that replacing the fillings doesn't remove all the mercury from the tooth. He says it's impossible and the mercury will be in the tooth for the rest of its life, and in our bodies to some degree, but that after time, depending how successful our detox, our bodies will go from toxic to a level that it can control.

I don't know if this is right/wrong but this is his view.
