getting ready to get the mercury fillings removed/need more info!!

I went to a holistic dentist today for a consultation. I made a date to get the mercury out. But here's my questions, she uses a dam, she doesn't have an air purifier, doesn't use oxygen as her protocal but said she would give it to me, and referred me to a doctor she uses to do a one week pre and one week post chelation therapy.
what do you think out there? I want to do this right. I could have sworn I had more fillings but the xrays only showed 1!! I'm wondering if I've swollowed mercury? anyway, is this the right protocal? Tweet
