Toothpaste in the shape of question mark coming out from toothpaste tube


Toothpastes can help prevent cavities, reduce tooth sensitivity, and clean and whiten teeth, but there are benefits and risk associated with the ingredients used to accomplish these goals. In this article, we discuss which ingredients you may want in your toothpaste and which you may want to avoid.

One of the world's most important scientific journals. Nature, has published a special news feature on water fluoridation, focusing on the Fluoride Action Network's federal court case against the U.S. EPA and quoting their legal counsel along with several accomplished neurotoxicity researchers. The message: you can fill a cavity, but you cannot fix damage to the brain. The title: "The Fluoride Wars Rage On".
One problem is a misplaced idea that decades of research on fluoride prove it is safe. It is ignoring the fact that almost none of these ‘decades’ of research have focused on the very specific issue of prenatal fluoride exposure and neurodevelopment...There hasn’t been a single US study of fluoridation, prenatal exposure and natal development.

See the section above titled "Natural toothpastes — Are they effective and safe?" for information about clay-based toothpastes.

As a person being treated for hypothyroidism, I was told by my doctor not to use fluoridated toothpaste because fluoride is close to Iodine on the Periodic Table and could cause interference in absorption. I have no financial interest in this subject.

We've added information about fluoride intake and thyroid dysfunction to our answer above:

I think it needs repeating that xylitol is toxic to dogs. People should not use toothpaste containing xylitol on their dog's teeth, nor leave it open on a counter within a dogs reach.

"Evidence-based," is music to my ears. Thank you.
