And early research seemed to say that fluoride, when it was put in water and available broadly, was something like a miracle defense against cavities, especially when it came to lower-income children who often didn't have regular access to dental care.

But along with people who thought it was miraculous, there have always been skeptics.

But for a long time, those concerns were considered fringe. For instance, in the 1964 movie Dr. Strangelove, this was the sign that one of the main characters had gone off the deep end.

But in recent years, new data has given fluoride skepticism new legitimacy. A number of studies have been published over the last decade about the impact of fluoride on the brain and thyroid. Some studies have shown that higher levels of exposure were associated with lower IQ, or ADHD. Other studies show that it could be harmful to a baby's neurological development.

The report, which came out in August, validated some of those concerns about fluoride. It found that at high levels, levels double what is allowed in U.S. drinking water, fluoride could negatively impact kids.

The report found with moderate confidence that elevated levels of fluoride could be associated with a decrease in IQ. One month after the report came out, a judge issued a major ruling against fluoride. This came after a group of parents had petitioned the Environmental Protection Agency about fluoride.

There's one more thing that's helped bring the fluoride debate into the mainstream. The rise of Robert F. Kennedy Jr.
