wiki doesn't mention this at all
Yes it does. In fact it has a whole article dedicated to it.
This quote seems especially relevant:
A major Australian study found no clear association between fluoridation and cancer or deaths due to cancer, both for cancer in general and also specifically for bone cancer and osteosarcoma,[7] and other adverse effects lack sufficient evidence to reach a confident conclusion.[13]
I've recently learned about alleged dangers to drinking fluoridated water. Amongst them is increased rate of cancer and lowering of IQ. Interestingly enough, wiki doesn't mention this at all, but searching for it brings up a decent amount of (what look like) reasonable results. I am really curious about this, and want to learn more about this. I was wondering if anyone on LW has already conducted a research literature investigation on this topic, or if you just have tips/advice on what to pay attention to when I read the literature.
Thanks!
