Utah becomes the first state to ban fluoride in public water.

Utah is close to banning fluoride in public water. This means cities can't choose to add fluoride, which helps prevent cavities. Some people think this sets a bad example for the whole country.

Although fluoride is good for teeth, some people are against it. They believe it should be a choice, not something added to water without their consent.

People who support fluoride say it's the cheapest way to keep teeth healthy, especially for poor people. They worry that without fluoride in water, more people will have cavities.

Most people in the US have fluoride in their water. But in Utah, very few water systems add fluoride.

Dentists in Utah are worried about the bill. They have seen firsthand how bad people's teeth are in places without fluoride in the water.
