Can you do any detox prior to removing crowns

Somehow it didn't include the actual message and now I have to write it all over again! :)

I was exposed to heavy pesticides as a kid and was lethargic most of my childhood. However, 2.5 years ago I had a really bad stomach flu and have been barely staying afloat since then. I have been treating lots of vitamin and mineral deficiencies and trying different supplements since then. I'm back to where I can function at work but am still not 100% yet.

I recently started on the Iodine protocol and have been reading more about mercury poisoning. I had 3-4 amalgam fillings that were replaced maybe 4 years ago. I now have (I think) 3 crowns, 1-2 of them with root canals. I'm not sure if they removed the amalgam fillings or if they're sitting below the porcelain covered crowns.

So my questions are:

1. Can I absolutely not do any sort of chelated with the crowns still in? It sounds like no, but i'm not sure the why on that.

2. Has anyone had regular crowns replaced recently with something else and can give an estimate how much they paid? I don't even want to waste the time meeting with a bio doctor if it's super expensive. The husband does not believe in alternative medicine and he's already getting fed up with all the money i'm spending on vitamins and supplements.

3. Is it worth the $50ish to buy Andrew Cutler's book or is most of that info online? I've found a lot of links, but I wasn't sure if reading the book was easier to assimilate the info from.

Thanks so much for all the insight! Amy
