What is the typical fluoride concentration recommended in drinking water?

• A. 1.2 mg/L
• B. 0.7 mg/L
• C. 0.5 mg/L
• D. 0.3 mg/L

Answer: (B)

The typical fluoride concentration recommended in drinking water is 0.7 mg/L. This recommendation comes from health organizations, including the U.S. Public Health Service, which aimed to balance the benefits of fluoride for dental health while minimizing the risk of dental fluorosis, a condition caused by excessive fluoride intake during tooth development. Fluoride has been recognized for its role in preventing tooth decay, especially in communities where the natural concentration of fluoride in water is low. The concentration of 0.7 mg/L is considered optimal and is a guideline to ensure that individuals, especially children, receive enough fluoride to strengthen tooth enamel without the potential negative effects that might occur at higher concentrations. Other concentrations listed, while they may have specific applications or results, do not align with the established recommendation for maintaining an effective and safe level of fluoride in drinking water. For instance, concentrations that are too high can lead to health issues, which is why the established recommendation is carefully set.
