What is the optimum concentration range for fluoride in drinking water?

The optimum concentration range for fluoride in drinking water is 0.8 to 1.2 mg/l. This specific range has been determined based on extensive research regarding the benefits of fluoride in preventing dental caries (tooth decay) while minimizing the risk of dental fluorosis, which can occur at higher concentrations. Regulating fluoride within this range promotes oral health by providing sufficient levels for cavity prevention, while ensuring that the risk of adverse effects is kept at a minimum.

Maintaining fluoride levels in this interval allows for effective public health measures, balancing the protective benefits and potential drawbacks of fluoride exposure. Other ranges either fall below the effectiveness needed for cavity prevention or exceed levels that may lead to complications, emphasizing the importance of adherence to the recognized optimum range.
