Water fluoridation is an important preventative measure carried
out in much of the western world. It results in some of the
hydroxyapatite, Ca5(PO4)3OH, of
which human tooth enamel is made being replaced by fluoroapatite,
Ca5(PO4)3F - a substance
significantly more resistant to decay. Thus, to protect the teeth
of the population, water is often fluoridated. This is usually done
with one of three fluorine-containing chemicals (sodium fluoride,
sodium fluorosilicate and hydrofluorosilicic acid). The following
equations describe the reactions that occur...
