Numerous studies have shown that fluoride is a neurotoxin and lowers children's IQ: A Harvard study found that "Children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas." Fluoride can drop your kids 7 IQ points, and yet we are paying extra taxes to put it in our drinking water.
I had to buy an expensive water filter for my home to filter out the fluoride that my tax dollars are paying to add in. Please, let's follow the majority of countries who have stopped this ludicrous practice. If you're really worried about dental health, take the money saved and provide free toothpaste to anyone who needs it.
