Science in Seconds - Fluoridation

0 (0 Likes / 0 Dislikes)
Science in Seconds Know Everything RUMOURS – Fluoridation Fluoridation of the water supply is recognized as one of the top public health developments of the 20th century. Despite this, some naysayers still suggest that the fluoridation of our drinking water is forced medication and acts to control the population. And the skepticism doesn't end there. Exceedingly high levels of fluoride exposure has been linked to cancer, bone deformities and retardation. Water causing cancer? Really? Exposure to levels of fluoride that exceed two milligrams per day can increase the risk of dental fluorosis, a cosmetic consequence where teeth take on white spots. We also know that consistent exposure to fluoride levels beyond this, about 10 milligrams a day, can cause skeletal fluorosis, a crippling bone condition. But that would require that someone eat at least a six ounce tube of toothpaste every day for years, without vomiting. The benefits of fluoridation outweigh the risks significantly. Fluoride works by increasing tooth enamel formation, which prevents tooth decay. Normal fluoride levels, of about one milligram per liter of water, have been shown to be completely safe for human consumption and has reduced the number of incidences of tooth decay by about 14 percent on average. But since fluoridation was proposed, it has met opposition from people who oppose things. Unfortunately for them, the science isn't on that side. There are a handful of studies that have shown that fluoride at super‑ high concentrations ‑ ‑ we're talking 200 times an average dose ‑ ‑ can cause damage to chromosomes and possibly increase the risk of a cancer called osteosarcoma. There's no debate that fluoride is toxic at high levels, but so is caffeine, sugar, salt, and even water, the non‑ fluoridated kind. Fluoridation of water is probably going to stick around for a while. To the anti‑ fluoride activists, I may sound like I've drunk the Kool‑ Aid made with fluoridated water, but science has made my cavity‑ free smile.

Communist plot to control the minds of the population or a really cheap and easy way to get some pearly whites? Anti-fluoride activists like to think that the government is forcing medication on us and controlling our brains, but the brains behind the science say otherwise.
