Bex. Sorry don't have too much time now to answer.

But, I never said amalgam removal is enough, so your concern about that is unnecessary. This is what I said:

"This negative effect of mercury usually clears within a few days after all the fillings have been removed, and then you have the burden of removing these infections."

So, what you need to do is to clear your infections, they can be viral, bacterial, parasitic in nature. I consider that the supplements I take are aimed at these and nothing else, even if ALA is included.
Mercury is anti-bacterial/fungal as well so it can actually kill pathogens too (ask any expert about why thimerosal is added into vaccines). The reason why you got bad reactions from visiting the dental office could be explained by this mechanism, and the symptoms you gave are really ammonia related (chest pain etc.), caused by a die-off. I also got some of them, but only when I attempted to kill pathogens. You can get these symptoms in various ways (mine came from use of B12), because many things work against pathogens. You should also take into account that the majority of the population in the world tolerates amalgam fillings well, regardless if their exposure is high, and they must accumulate mercury too.

On the top of my head, one reason why DMSA could be effective is that hydrogen sulfide binds to same things as mercury, so DMSA will chelate hydrogen sulfide from gut dysbiosis as well (you have wrong bacterias in gut, producing too much toxic hydrogen sulfide). To the best of my knowledge, it will give better results, if one concentrates more on the pathogens than on mercury.
