Some Anglosphere countries (USA, Canada, Ireland, Australia) love to add fluoride in water. They say it’s good for people’s dental health.
Europeans (Germany, Finland, Italy, France, Netherlands, Switzeland) think it’s wrong/unethical.
There is actually regular controversy around this

Do they put fluoride in your drinking water ? Are you happy with that?
Nope.
You get it from salt and toothpaste.
The way a dentist explained it to me is that having it in the drinking water helps kids whose teeth are still developing and will integrate it directly into the tissue. After that, topical via toothpaste and in office treatments helps adults.
BUT take that with a grain of salt because (1) drinking water fluoride should have topical benefits too right? And (2) you should place more trust in organizations and bodies of research than a secondhand anecdote from a single dentist.
