For those waters that have an excessive concentration of fluorides (“fluoride” and not “fluorine”, because that is the form in which the element fluorine is present in the water), there are several ways of reducing it to the recommendable levels for a good dental health of the population. However, it should be clear that if the population is too big, the tendency is to try to find another source of supply, since normally surface water does not have high fluoride concentrations and to avoid treatment of large amounts of water. Activated Alumina It is a material of interchange and functions like a common and simple interchanger. In the United States of America this material is widely used, and is used in the majority of the world where there are problems with fluorides. Ground Bone It is also an ionic interchange technique. The difference is that the interchangeable material is ground and ungreased bone. This technique was perfected in Argentina. The SNAP (National Service of Potable Wat
