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.
Another study that year which tracked the fluoride consumption of more than 600 schoolchildren in Iowa showed there was no significant link between fluoride ingestion and tooth decay.
According to Sheldon, that’s a “huge number.” A total of 40 percent of people in fluoridated areas have some level of fluorosis, though the majority of these cases are likely unnoticeable to the average person.inequality when it comes to fluorosis.
Blacks and Mexican-Americans have higher rates of both moderate and severe forms of the condition. As of 2004, 58 percent of African-Americans had fluorosis, compared to 36 percent of whites, and the condition is becoming more common.maintains on its website that “thousands of studies” support fluoridation’s effectiveness—which is directly contradicted by the Cochrane findings.
See all of the Thomas Zoeller, a scientist at UMass-Amherst uninvolved in the work.two-thirds of Americans, fluoride is added to your tap water for the purpose of reducing cavities.But the scientific rationale for putting it there may be outdated, and no longer as clear-cut as was once thought.But more than two-thirds percent of the studies showing this took place more than 40 years ago, and are not of high quality.Nearly all these papers were flawed in significant ways.
So while it may have once made sense to add fluoride to water, it no longer appears to be necessary or useful, Thiessen says.according to the CDC.
