What are the benefits and problems with water fluoridation?
Optimum Water Fluoride Concentration & The Fluoridation Controversy The fluorides are ubiquitous in nature and are present in foods, water, plants, rocks, soil and even air. The main contribution of fluoride to human beings is from water and only in some endemic areas significant amounts also come from food. The relationship between fluoride and dental caries was first noted in the early part of the 20th century when it was observed that residents of certain areas of U.S.A. developed brown stains on their teeth. These stained teeth, though unsightly were highly resistant to dental decay and caries. In the 1930’s it was discovered that the prevalence and severity of this type of mottled enamel was directly related to the amount of fluoride in the water. Subsequently it was recognized that fluoride consumption in optimal amounts in the water supply imparted protection against the development of dental caries without staining the teeth. Another benefit of fluorides is that the incidence o
