A patient of ours Laura Trotter runs an eco-friendly living website. I had the pleasure of being interviewed by her on the topic of fluoride in water. I think she has given all sides of the argument to help you decide on what you would like to do. My opinion was certainly voiced fairly in this fiery topic.
