What they are saying is absolutely true. I learned that in college years ago.
You know why floride kills bacteria? Because it is a freaking poison. It's ok to use it to brush your teeth (and spit it out) but it really is not good to ingest it. My household has not used it in years. The risk is not worth the relatively small gains. Just teach kids to brush their teeth.
We are learning all the time and it is not unusual to reverse a long held therapy because we learn it is not so good for you. It doesn't help that in our system industry lobbies make it harder to make change when science learns of a problem.
It wasn't that long ago that they used to have people ingest radioactive iodine to get "better xrays" . Then oops, not such a good idea!
Maybe you are too young to remember that this is what most of our investigative reporting used to look like (without the Rachel Maddow edge, which is who she seem to be emulating).
