In terms of water treatment, what is the primary objective of using fluoride?

The primary objective of using fluoride in water treatment is to prevent tooth decay. Fluoride has been widely recognized for its role in dental health, as it can strengthen tooth enamel and make it more resistant to acid attacks from plaque bacteria and sugars in the mouth. This preventative measure has proven effective in reducing the incidence of cavities in both children and adults when fluoride is present at optimal levels in community water supplies.

While improving taste, enhancing nutritional content, and reducing mineral content may seem beneficial, they are not the primary reasons for adding fluoride to drinking water. The focus of fluoride use is specifically on its ability to contribute to oral health, making its inclusion in public water systems a key public health measure aimed at reducing dental caries and promoting overall community health. This targeted approach is rooted in extensive research demonstrating fluoridation's effectiveness in preventing tooth decay across populations.
