This guy, Peter, is a dentist. He does teeth. He does not do chelation. He has been mercury free practice for 15 years, maybe more. For the specifics you will have to speak to them. He uses rubber dam, oxygen, has air filters. Give him a call. His secretary Gloria is very very helpful. I called her many times to ask questions, she knew everything from the top of her head, she did not umm and err, nor need to look anything up. Anything she didn’t know Peter came on the line within seconds and told me what I wanted to know. He is a member of ioamt.
