The risk of cavities is reduced by using toothpaste or mouth washes with fluoride, not by drinking fluoridated water.
Almost all fluoride from the drinking water does not have any effect on tooth enamel, because it has contact with it only for a few seconds, except for an infinitesimal fraction that may exit again the body in saliva.
On the other hand, the harmful effects of fluoride in drinking water are certain and it cannot be predicted exactly how much water will be ingested by someone, i.e. which will be the harmful dose of ingested fluoride.
The only argument of those who support water fluoridation is that most people must be morons who cannot be taught to wash their teeth. I do not believe that this theory can be right.

it always surprises me how willing people are to just make something up and be confident in doing so. We've know for almost 75 years that water fluoridation reduces tooth decay[1] and yet here you are straight up denying that.
Do you just not care if you are correct? or do you know you aren't but are driven by the beliefs you already hold?

The contact via toothpaste or mouth wash isn’t all that much longer, so why would they be effective if fluoridated water isn’t? People intentionally wash out toothpaste and mouthwash after this short contact.
