my thoughts on chelation

ok i have visted three sites that recommend cilantro pesto for helping with heavy metals. none of them say that you cant have fillings in to do it. Just wondering why people say that you cant do any chelation when you have mercury still in. there are millions of people who eat daily as part of there diet cilantro and garlic, usally in the same dish (ie indian) and if half of these people have metal fillings in then woiuldnt they be dropping down dead from pulling mercury out of there fillings?. also i take 3000g vitc a day. vitc helps support the liver and detoxes metal from body. is this then not harmful. also there are lots of products, partic homepathy stuff that says that is perfectly fine for people still with fillings. what about detox pads, detox saunas, clay baths, vitamins, dandelion and milk thitsle etc for helping to clean your blood and liver. are these not safe while you have fillings. just a thought
this is not to cause arguements im just interested in what peiople think
