How Much Fluoride Is in My Water?

Simply put, the fluoride level in your tap water can vary, as some utilities do not report measurements. The only way to determine how much fluoride is in your water is to conduct a water test if your water quality report does not include this information.

In 2004, the World Health Organization (WHO) reported that 99.8% of public American drinking water has fluoride content below 2 milligrams per liter (mg/L). In 2015, the U.S. Public Health Service recommended reducing the fluoridation of public drinking water to 0.7 mg/L. The organization acknowledged that the general population has access to fluoride through toothpaste and mouth rinses.

This recommendation does not mean that utilities always add 0.7 mg/L of fluoride to your water. Practices differ across the country. Maintaining a consistent fluoride level in the public water supply is challenging due to fluorine’s reactive qualities.

While the Environmental Protection Agency (EPA) set a maximum contaminant level for fluoride at 4 mg/L, the WHO recommends a maximum fluoride value of 1.5 mg/L to minimize dental fluorosis.
