The addition of fluoride (fluoridation) to drinking water that is low in fluoride or the use of fluoride toothpaste and supplements significantly reduces the risk of tooth decay.
Jeez, you really can't read, can you?
I don't expect you to be capable of making worthwhile arguments, so I'm just going to end this here.

What? We put fluoride in water because people can't afford toothpaste or brush their teeth? That's news to me.
So you're saying that there's no point in having fluoridated water if you have proper dental hygiene?
