Tooth staining a fluoride side effect
Patterson’s cartoon depicting a couple with sparkling white teeth departing from a drinking fountain dispensing fluoridated water (Times, Oct 25) is more humorous than intended because, in fact, fluoridated water causes staining of teeth, technically known as fluorosis.
In 2015, the Cochrane collaboration, acknowledged internationally as the gold standard in the review of health science, published the results of a substantial, highquality meta study.
This review found that for a fluoride level of only 0.7 parts per million, the incidence of dental fluorosis ranged from 12 per cent with fluorosis of aesthetic concern to a substantial 40 per cent with fluorosis of any level.
The Cochrane authors also concluded; “There is very little contemporary evidence, meeting the review’s inclusion criteria, that has evaluated the effectiveness of water fluoridation for the prevention of caries.” John Vukovich, Fluoride Free Bunbury
