No evidence dental flossing matters

Another health sciences correctitude goes down in flames.

From Big Story:

Last year, the Associated Press asked the departments of Health and Human Services and Agriculture for their evidence, and followed up with written requests under the Freedom of Information Act.

When the federal government issued its latest dietary guidelines this year, the flossing recommendation had been removed, without notice. In a letter to the AP, the government acknowledged the effectiveness of flossing had never been researched, as required.

The AP looked at the most rigorous research conducted over the past decade, focusing on 25 studies that generally compared the use of a toothbrush with the combination of toothbrushes and floss. The findings? The evidence for flossing is “weak, very unreliable,” of “very low” quality, and carries “a moderate to large potential for bias.” More.

Of course, we need to be just as cautious with claims made by debunkers as with claims made by fatuous asses who “stand for science!”

With flossing, as with nutrition in general, a key problem is that one can’t measure health benefits among self-reporting humans the way one can measure them among test animals in an enclosed and controlled environment.

As a result, I (O’Leary for News) have much more confidence in the products recommended for my animals (including tooth health products) than I have in those recommended for me.

The problem is that we are seeking general truths from nutrition practices whereas benefits may vary widely within the human population.

Flossing (assuming it is a rigorous practice) may help some people much more than others. Salt or butter may be against sound medical advice for some people but not for most people.

Whole foods may have a psychological health benefit to some people that makes the extra expense worthwhile. I know women fighting breast cancer who get right into all that stuff. That’s good. Their approach to their disease leaves them much happier because they are doing something more pleasant than consuming their lives with worry—no matter what the outcome in five-year survival rates. They may not live longer, but they won’t really notice.

It’s the big public campaigns about all this stuff that need debunking. Which leads us to the conundrum that, just when all the nonsense is coming out in the wash in serious science, we have municipal Napoleons banninglarge-size soda pop and fast food. And creating court costs for the taxpayer when industry sues back.

A wise voter should infer that any mayor engaged in such activities is trying to evade boring, non-Napoleonic duties like infrastructure maintenance and renewal. And that voter should vote to allow him to continue with his food concerns on his private time.

      And we get to pay for refugee dental care…..

    One benefit is not having to put leftovers in the fridge.

    Just pick yesterday’s steak out at lunch the next day.

    I’m going with the debunking studies being b.s. on this one personally. (And I have crappy dental hygiene so I’m not some flossing psycho pulling for “my” side.)

    • That’s why I say be cautious. Flossing probably does help people who are prone to cavities. The more cavities a person has, the more can build, hence the more need to prevent them. But maybe not everyone is prone to cavities, especially if they have none in the first place, so bacteria can’t get an easy hold. The thing is, in the present day, it is just not rigorous science.

    This is a very odd development

    Much of this “healthy living overlordship for our own good” by our totalitarian betters is strictly obedience training to keep the herd in line, and just as important, keep the herders in line..

    Well at least for the moment we can make our own choice.

    I floss rigorously as my dentist requests but what I have found makes the difference is not having a dry mouth. If you take medication, you are likely suffering from it. I have had no cavities since I started using biotene gel at night. With just the flossing I always required filings.No longer.
