The debate about adding fluoride to water: health benefits versus possible dangers.

For a long time, many places in the US put fluoride in their water to help people have healthier teeth. But now, some places are stopping this because some people are worried that fluoride might be bad for kids' brains.

There are a few reasons why people are worried about fluoride. One reason is that a judge said that the government needs to check if fluoride in water is safe for kids.

Another reason is that a group of scientists said that too much fluoride might make kids' brains not work as well. This group looked at studies from different countries and found this link.

Even though some people are worried, many doctors and dentists still think fluoride in water is a good idea. They say it helps prevent cavities and is safe at the levels currently used.

The government is still looking into whether fluoride in water is safe. In the meantime, some places are stopping fluoride, while others are keeping it or even starting to use it again.
