Fluorinating all of the water just to deliver some milligrams to the teeth is incredibly inefficient. Especially when less and less of the stuff people people drink comes out of the tap.

We have toothpastes and fluorinated mouthwash that both get the job done.

Probably there are some people that are unable to afford those and unaware how to use them, but probably are tiny percentage of the state population, especially with the cult of teeth care that the US has.

I also see the fortified flours as example (or iodine in salt) - but the US is different now than in the 30s. The US diet is more varied. Very few people get 80% of their calories from a single starchy staple so developing a severe deficiency of something requires some serious effort from the persons affected.

So who is this policy of fluorination for - the people that are too poor to afford toothpaste, but still have access to municipality treated water and don't drink copious amounts of soda or bottled drinks.
