Where does toothpaste fall on this scale?

• FrozenVoid 8y ago
  Fluoride toothpastes sold in the U.S. generally contain between 1,100 and 1,450 parts per million (ppm) fluoride (the equivalent of over 1 mg of fluoride for each gram of paste). http://fluoridealert.org/issues/dental-products/toothpastes/ http://fluoridealert.org/issues/dental-products/toothpastes/

    Is that enough to lower intelligence? I couldn’t seem to figure it out from the paper.

      The authors of the paper wouldn't claim to know. They measured levels in urine and have no idea where that fluoride came from.

      Maybe if you change your brand of toothpaste you will?
