Tibetians get fluorosis through drinking tea!
Letter by T S Raman
I am a scientist, and till today, I have been unable to find definitive scientific evidence for the purported benefits of fluoride. Especially, there is no experimental (interventional) evidence, and all the panegyrics on fluoride have been based on stray, 50-year old observations made by people NOT trained in science. Some months back I asked the American Dental Association (on line) for information, but they have not replied.
By the way, how do you "adjust[..] the fluoride content that occurs naturally in a community's water to the best level"? If the "naturally" occurring fluoride content in the water is too high (as is the case in many, many parts of the world, including ALL continents), there is no simple or easy way to reduce it to the "best level".
Also, the fluoride that the people ingest does not always come entirely from water. For instance, it is well known that ground-water in Tibet does not contain much fluoride, but dental and skeletal fluorosis is common there. The dietary source of the excess fluoride is tea.
It is about time proponents of fluoridation gave up their pig-headedness and looked at facts, especially recent scientific findings, recent WHO documents, and so on.
