Is there enough fluoride in a tube of toothpaste to kill a small child?

Is the following statement supported by epidemiological evidence or toxicological data? sodium fluoride is so toxic that there is enough in a tube of toothpaste to kill a small child A recent news article (actually, a submitted opinion article, which is often treated like “news”) says “sodium fluoride is so toxic that there is enough in a tube of toothpaste to kill a small child”.

The Reverse Logic of Fluoridation Opponents

I’d like to think that fluoridation opponents are merely wrong or mistaken, but here is an example of the reverse logic and obviously irrelevant claims that they use to support an argument (and they apparently consider this to be one of their better ones).

For example, I have stumbled upon the provocative ideas that global warming is not real (or at least is not related to human activities in any important way), vaccination causes autism, the world is only 6,000 years old, condensation trails from aircraft are really a method to manipulate weather patterns, and that people are adding fluoride to drinking water in order to poison […]

Facing Facts: The value of science

Editor’s Note: We are very pleased to announce our first serious post to this site, the text of a speech by Bryson Brown at the Stand Up for Science Rally at the University of Lethbridge on Monday, Sept. 16. Facing Facts:  The value of science Bryson Brown, Lethbridge We’re here to protest against something quite frightening—a government that seems intent on suppressing evidence rather than responding to it.  But I’m a philosopher, with a long […]
