#112I also brush my teeth before I go to bed, so this would just be a huge mistake waiting to happen...

#113Missed a trick with 'Power Paste' I think.

#114LD50 is 75–100 cups of coffee for a 70 kilogram adult... so eating a tube of this can be fatal for adults. Don't leave this where children can find it.
If you are afraid of your children eating dangerous amounts of something from a tube, look no further than normal toothpaste.

#115I go back and forth on the whole fluoridation issue. I personally think that a proper diet negates any reason to us fluoride, and ingesting it intuitively seems like a bad idea. Not sure if that's rational. But that's why I buy toothpaste containing Novamin rather than fluoride. (strangely, you can only buy it from overseas and they pulled it off the shelves in the US)

#116Earlier quoted context omitted.
The US Dept of Health and Human Services actually halved their recommendation for fluoride in water about six months ago. The reasoning is apparently that people in the US now get enough from other sources such as toothpaste, mouth washes, etc [1]. Note that they didn't /remove/ the recommendation for fluoride in water. They just reduced the recommended amount. 1: http://www.npr.org/sections/health-shots/2015/04/27/4…
Getting too much fluoride is something that can occur as well: https://en.wikipedia.org/wiki/Dental_fluorosis
I am all too aware as I have mild fluorosis in some of my teeth! Although I think the biggest cause of this was semi regular fluoride rinses at the dentist when I was a kid.

#117I was down voted to hell for saying this in the past, but I'll share it again:
One of my dads best friends was head of ALCOA, John Haymaker:
Quote: "aluminum production produces fluoride acid - a substance so toxic that we cannot dispose of it... So we began fluoridation of the water because the only place we can store it is in your liver"
And for those that toe the line with dental benefit BS: if the government was so fucking concerned with your dental health - why isn't any other medical benefit made free and literally forced upon you like fluoride is???

#118> Power Toothpaste does not contain Fluoride. We know many of you don't want fluoride in your toothpaste. This seems bizarre to me. People don't want fluoride in their toothpaste? Why not? Dentists seem pretty unanimous that everyone should brush twice a day with fluoride toothpaste.
Yeah. This stuck out to me too. $15 dollars for a tube of toothpaste that doesn't contain flouride? What am I paying for? I'll just buy my own caffeine powder and use real toothpaste that's only $2.

I wrote a longer comment about this below, but the essential reason is: if I made fluoride a product requirement, I wouldn't have gotten to a release. It would have added a huge expense. Additionally, fluoride is much more important for children. As enamel is forming, fluoride interacts with it and strengthens it. Adults need far less (threshold dose effect) and for most people in the United States, they likely get e…
As a guy living in Europe, it seems more logical to drink unfluoridated water and use fluoridated toothpaste, but that's America over there… Cool idea, for sure.
