Death By Colgate

So I was out by a factor of 100 or 1000 or something. I wrote:

Now, I have in front of me 100ml of Colgate. On the ingredients, it says it's 0.32% NaF, which works out at 0.32mg. So, your 85kg chappy would have to eat 12500 tubes of Colgate to die- that's 1250 litres!

0.32% of 100ml is 0.32g, not 0.32mg. So that's where I went wrong. I can't be bothered to redo the sums- best forget about this one.
