Hopefully I did that?
Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub:

Anyway, if this shouldn't have been Show HN, I apologize!
It is factually correct fluoride can be dangerous and studies have shown that. It is also factually correct fluoride in water reduces cavities. The debate is the risk rewards lines and safety.

> Federal officials have recommended a fluoridation level of 0.7 milligrams per liter of water as of 2015. This is a decrease from the recommended upper ranger of 1.2 milligrams from the 50 years before that. Meanwhile, the EP has a longstanding requirement that water systems cannot have over 4 milligrams of fluoride per liter of water. For comparison, the international safe limit for fluoride in drinking water as stated by the World Health Organization (WHO) is 1.5 milligrams
The A/B testing you reference in Canada is interesting data obviously. It’s also possible reducing cavities with fluoride comes at an IQ cost isn’t it?
There's no evidence to suggest that though.
Just evidence that high levels (much higher) of fluoride and other elements in water has an adverse effect.
