Thanks for the responses. Sorry to hear about the kids and unneccessary work done on them. I've come to the point where I don't trust many people nowadays. Like blueduck said, after looking at (what I consider to be) 100% proof of harm done by mercury etc... and why most dentists disagree, there must be conflict of interest there. #1 rule is do no harm - I guess that flew out the window when there's money to be made.
