According to the Academy of General Dentistry, adding fluoride to public water supplies is considered to be the most cost-effective way to help prevent cavities and fight tooth decay. Communities have been adding fluoride to water supplies since 1945. Water fluoridation has been shown to be safe.

Recommended levels of fluoride within community water helps to prevent tooth decay in both adults and children. The best available scientific evidence over 65 years demonstrates it’s highly effective and safe.
Jerry Gordon, Dentistry, answeredThe main thing to know about drinking tap water with fluoride is that it is safe and has been proven to be the most cost-effective way to reduce the incidence of tooth decay. If your children are getting chalky discolorations of their teeth, they may be getting too much fluoride. The EPA recommends a water concentration of no more than 0.7 ppm.
