Is all the Amalgam out of your mouth? If it is I really recommend starting the low dose frequent chelation if you have no Amalgam left. It's hard to tell from your post. But only if its ALL gone, otherwise you could cause yourself more problems. I'm not sure how it can leak mercury if its out, if you accidentally swallowed it you should be fine. Studies have shown absorption from solid mercury is very poor
If not see if you can pay a dentist to just drill the rest of it out.
I didn't believe chelation would work until I did it on myself. And man its making a huge difference
