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.
That's a loaded question because people do not suffer without fluoridated water.
Do you want to explain how they suffer without fluoridated water? That way you're talking specifics that can actually be debated upon instead of generalities where people need to make your arguments for you.
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?
