I went to Nuevo Progresso, Mexico had 18 Amalgam replaced with gold. Cost about 2200. You can find someone to do it even cheaper especially under the current political situation. Mexican gold is probably not the best. But then you cant trust most US dentists either. Even with no protocols I did not notice any acute toxicity more than a can of tuna fish. I did use activated charcoal. Dont chelate with ALA alpha lipoic acid for at least 3 months.
