Millions of people in England receive fluoridated water. This means fluoride has been added to bring it up to around 1mg of fluoride per litre of water, which is a level found to reduce tooth decay levels.

Now I know there is a running joke around the English having bad teeth. But I imagine if millions of people were having issues we’d know about it.

Added fluoride is done at safe levels. But some natural water sources have TOO MuCH fluoride which is unsafe. https://en.wikipedia.org/wiki/Fluoride_toxicity#Bones
