Misinformation campaigns increasingly target the cavity-fighting mineral, prompting communities to reverse mandates. Dentists are enraged. Parents are caught in the middle.

The culture wars have a new target: your teeth.

Communities across the U.S. are ending public water fluoridation programs, often spurred by groups that insist that people should decide whether they want the mineral — long proven to fight cavities — added to their water supplies.

The push to flush it from water systems seems to be increasingly fueled by pandemic-related mistrust of government oversteps and misleading claims, experts say, that fluoride is harmful.

The anti-fluoridation movement gained steam with Covid,” said Dr. Meg Lochary, a pediatric dentist in Union County, North Carolina. “We’ve seen an increase of people who either don’t want fluoride or are skeptical about it.”

There should be no question about the dental benefits of fluoride, Lochary and other experts say. Major public health groups, including the American Dental Association, the American Academy of Pediatrics and the Centers for Disease Control and Prevention, support the use of fluoridated water. All cite studies that show it reduces tooth decay by 25%.

    I’m having thyroid problems, and in trying to research iodine, I have found that fluoride can have a negative impact on thyroid function. This link is the best I can do on the subject, given that I’m not sure how to find much trustworthy information. It says that as long as iodine intake is sufficient, the fluoride shouldn’t be a problem. But I’m finding conflicting info on what constitutes sufficient iodine intake.

      If you consume any iodized salt you should be good on that, unless you have a medical condition that prevents your body from absorbing it properly. In fact people don’t really get goiters anymore since the introduction of iodized salt which was done to prevent said goiters(a goiter is a swollen thyroid from lack of iodine intake iirc).

        I was not using iodized salt at all. I think since “elevated” cooking has become so popular, I can’t be the only one who was eschewing it (Salt, Fat, Acid, Heat straight up recommends avoiding it). I also don’t eat much seafood. When I was diagnosed hypothyroid 25 years ago, I was told I had a goiter. And not told much else.

          I’m just an internet rando, but I’d definitely recommend talking to your doctor about iodized salt intake or alternatives. Iodine was added to salt when they figured out people living in middle America away from the shorelines had severe iodine deficiencies and goiters were very common. That’s all I know about it. I just like weird history tidbits like that

      Interesting, thanks for the link! I figured there had to be something to it because he’s a really smart guy and not in any way conspiratorial. His teeth are also in great shape so his way of living doesn’t appear to be hurting anyone.

      For the record, he was not preaching. I was just filling up from the kitchen sink while he used the filtered water thingy so it came up. He was talking only about himself when he expressed his concern
