Australia - Fluoride Fear

Oct. 31, 2014, 12:30 a.m.
From Pathobiology of Human Disease, A Dynamic Encyclopedia of Disease Mechanisms 2014: "Dental fluorosis is a developmental disturbance of the dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity."
A large percentage of children in Australia have dental fluorosis. Why is it that nobody refers to the fact that fluoride reduces mineral content and increases porosity? Surely increased porosity cannot be seen as a beneficial effect?
