  • Review of fluoride removal from drinking water - EDGE

    Fluoride in drinking water has a profound effect on teeth and bones. Fluoride displaces hydroxide ions from hydroxyapatite, Ca5(PO4)3OH, the principal mineral constituent of teeth (in partic-ular the enamel) and bones, to form the harder and tougher fluo-roapatite, Ca5(PO4)3F. Up to a small level this strengthens the enamel.
