What are the Recommended Guidelines for Fluoride Intake?
Various health organizations have established guidelines to minimize the risk of fluoride toxicity while maximizing its dental benefits. The World Health Organization (WHO) recommends a fluoride concentration of 0.5 to 1.0 mg/L in drinking water. The U.S. Environmental Protection Agency (EPA) has set the maximum contaminant level for fluoride in drinking water at 4.0 mg/L, with a secondary standard of 2.0 mg/L to prevent dental fluorosis.
