Raji, It sounds like your dentist knows what he's doing. You usually don't detox before a removal, but my dentist also had me take chlorella the morning of the removal. This provided my digestive system with enough sulfur to absorb mercury that escapes during the removal. I think it's a good idea to take it the day of the procedure, but I personally would not take it before that day.

Putting it on your teeth after the removal is a good tactic to pull latent mercury out of the teeth because of the high sulfur content of chlorella.

Let us know how it goes.
