I just read some of that article. That makes me wonder, would just using fluoride in toothpaste be enough? Should the fluoride really need to be drank in the water? I would think the superfical exposure to be what is necessary; yes or no?

I think the underlying assumption is that some segments of the population don't reliably use toothpaste. Adding it to water is a bit of insurance.

Bad teeth or bad brain, seems like a bit of Sophie's choice.
Reminds of when the consensus in 2020 was that alcohol 'killed' or at least rendered SARS-CoV-2 not viable.
So, if we kept a certain level of alcohol in our system all the time we gain some protection?
It was tongue in cheek, it was a strange time.

The man had a point.
 
According to wiki, only 2% of europeans have fluoridated municipal water, and most of that is in the UK. (ref)

wiki said:
Many European countries have rejected water fluoridation, including: Austria, Belgium, Finland, France, Germany, Hungary, Luxembourg, Netherlands, Northern Ireland, Norway, Sweden, Switzerland, Scotland, Iceland, and Italy. A 2003 survey of over 500 Europeans from 16 countries concluded that "the vast majority of people opposed water fluoridation".

Sounds like a 'U.S.' centric topic.
Anyways, I recall being involved in a 'fluoride' conversation in the past:

PF: Portlandia has struck again: fluoride in water​

PORTLAND, Ore. (AP) — The mayor of Portland, Ore., has conceded defeat in an effort to add fluoride to the city's drinking water.​

hmmm.... Maybe that's why I'm so smart! For most of my life I've drank non-fluoridated water.

Smart, maybe. Grammatical, no

“Have” is the helping verb for the present perfect tense, and we form the present perfect by using have/has + the past participle. The past participle of drink is drunk. So we always say have drunk, never “have drank.”

I have drunk the Kool-Aid, and therefore will die.

I did drink the Kool-Aid, and therefore will die.

Ok. I think I've got it, for now.

Yesterday, I couldn't remember if I had eaten diner or dinner, even though up until the 10th of last month I always got it right.
I'm monitoring my descent into senility by keeping a diary.

I actually vacillated over whether or not to use "That's why I used to be so smart..." in my above post. I look at my posts from years ago and no longer recognize that person.
