Sadly yes, you will have got mercury contamination from having your fillings drilled out.

It is not safe to chelate until all your amalgams are removed. If you chelate with amalgams still in, you pull even more mercury out of your fillings and you will likely get worse.

Read these books.....they will explain:

"It's all in your head" by Hal Huggins...available on amazon

"Amalgam illness" By Andrew Cutler

available here: http://www.noamalgam.com/#howtoorder

Both are essentail reading. Huggins explains how and why you got poisoned, Cutler explains how to safely get better.

Get reading and good luck.
