No, in fact, fluorides occur in many natural water sources.
Easy answer, its not very effective, It is a toxic substance and can cause thyroid damage and other health problems.

"Fluoridation of water," said R Strange.
Community water fluoridation was first introduced in Grand Rapids, Michigan, in 1945. This initiative aimed to reduce dental cavities among the population by adjusting the fluoride levels in drinking water. The success of this program led to widespread adoption of water fluoridation across many cities in the United States and around the world.
Because dentists would rather treat the water than poor people

It is called sodium fluoride, and it is used in toothpastes and in fluoridation of water, because the fluoride strengthens tooth enamel.
All things are toxic at a sufficiently high dose or if the exposure is at a sufficiently high dose rate. Even water is toxic and people have died by drinking too much water too fast. At the normal exposures one gets to fluoride it is not toxic (and even significantly helps teeth resist tooth decay). However one exception to this is very young children should never be allowed to brush their teeth with a toothpaste containing fluoride as they tend to swallow the toothpaste instead of spitting it out and toothpaste tends to taste like candy so some very young children also eat it, there have been cases where such children have reached toxic doses of fluoride (especially in areas where the drinking water also contains fluoride either naturally or via artificial fluoridation).
Toxic is an adjective.
