I remember one oral surgeon telling me that they add fluoride to the water to prevent cavities and make teeth stronger. I am wondering whether he really believed that or was misinforming me. No fluoride is good for you, even in the toothpastes, so why drink it? How do you avoid fluoride Russ? My shower filter removes chloride, but I don’t think it removes fluoride, for it doesn’t say that it does. Does your filter removes fluoride along with chloride?
