That is absolutely inaccurate to say there are no side effects from amalgam fillings @janus27. I have spent over 28 years of my life very ill from just that. I have done nothing but research these fillings and the side effects they present while in your mouth and after they are out for well over 6 years now, most of the time all day every day when I was too sick to get out of bed and do anything else. I started having fillings put in when I was about 6 or 7 years old and have felt very off with a whole host of illness that followed ever since then. From 2010 to 2014 I sat knocking on deaths door daily while trying to figure out why I was so ill. I saw 28 western medicine doctors who were much more comfortable telling me it was all in my head rather then helping me address the real issue of toxicity. So after tens of thousands of dollars and an entire hellish lifetime (so far), I can say without a doubt that amalgam fillings are detrimental anyone's health who has them. The minute I had my last filling removed it was as if this huge black invisible cloud that had followed above me the majority of my life just blew away and I couldn't stop smiling. I naturally detox more and more each day and my health is returning - but it is a slow process. There is a mountain of actual scientific evidence that shows how awful the effects of amalgam fillings are on the body. One woman finally even won a court case to this point. https://iaomt.org/leading-activist-freya-koss-settles-long-standing-amalgam-injury-case/
As for fluoride - you need to do a lot more than not drink tea if you want to avoid the effects of that.
