Indeed, cavity rates This condition occurs when fluoride interferes with the cells that produce enamel, creating white flecks on the teeth.On average, about 12 percent of people in fluoridated areas have fluorosis bad enough that it qualifies as an “aesthetic concern,” according to the review.They write: “We have limited confidence in the size of this effect due to the high risk of bias within the studies and the lack of contemporary evidence.” Six of the nine studies were from before 1975, before fluoride toothpaste was widely available.The review also found fluoridation was associated with a 14 percent increase in the number of children without any cavities.Across all nine studies included in the review looking at caries reductions in children's permanent choppers, there was evidence linking fluoridation to 26 percent decline in the prevalence of decayed, missing or filled permanent teeth.But the researchers say they have serious doubts about the validity of this number.Thus, there's no good reason to swallow fluoride and subject every tissue of your body to it, Thiessen says.2009 review by the Cochrane group clearly shows that fluoride toothpaste prevents cavities, serving as a useful counterpoint to fluoridation’s uncertain benefits.
Nearly all these papers were flawed in significant ways.“My prior view was completely reversed."2001 study covered in the Cochrane review of two neighboring British Columbia communities found that when fluoridation was stopped in one city, cavity prevalence actually went down slightly amongst schoolchildren, while cavity rates in the fluoridated community remained stable.“The fact that there is insufficient information to determine whether fluoridation reduces social inequalities in dental health is troublesome given that this is often cited as a reason for fluoridating water,” say Studies that attest to the effectiveness of fluoridation were generally done before the widespread usage of fluoride-containing dental products like rinses and toothpastes in the 1970s and later, according to the recent Cochrane study.“This study does not support the use of fluoride in drinking water.” Trevor Sheldon concurred.Sheldon is the dean of the Hull York Medical School in the United Kingdom who led the advisory board that conducted a systematic review of water fluoridation in 2000, that came to similar conclusions as the Cochrane review.
