Fluoride supplementation is widely recommended in mitigating dental health problems. However, excess doses prove dangerous to health and can provoke a potentially highly disabling disease, namely fluorosis. Fluoride in high doses attacks teeth and, in extreme cases, bones. Excess doses are generally due to the intake of fluoride-rich water. Groundwater with high levels of fluoride exists in many places throughout the world, particularly in developing countries, but high fluoride concentrations are also observed in groundwater in Europe and North America. The danger of fluoride remains concealed as it has no taste and does not form a deposit; consequently, a high percentage of population suffering from fluorosis is not aware of the risk until significant spread of the disease.
