I'm not the one you asked, but adding fluoride to tap water was a revolution in dental health, so yeah.
Just like most things, concentration matters. A little fluoride is very good for you. A lot of fluoride is bad for you. They put a "very good for you" amount in the water, and if you don't get it from the water you should take supplements.
You may have seen conspiracy theories about fluoride addition which have existed since the 70s, but those have about as much credibility as chemtrails.
Don't know about any conspiracy theories, but my take is tapwater should be as clean as possible without any additives. Fluoride is in fish, fruits, toothpaste, make sure you eat healthy enough so you don't need your water source to be "contaminated".
But I guess in the US and the food quality its better than nothing.
The introduction of flouride to drinking water saw a massive improvement in the public's dental health across the board. It is still widely considered to be one of the greatest public health initiatives of the 20th century.
You should also keep in mind that drinking water always has some level of natural flouride in it. Just the concentration varies by region. Public health officials discovered that areas with higher amounts of natural flouride also had lower rates of cavities and tooth decay. So some cities have their water flouridated to bring their flouride content up to beneficial levels.
Adding fluoride to water is not US specific.
