What is the primary purpose of fluoridation in municipal water supplies?

Fluoridation of municipal water supplies is primarily aimed at preventing dental decay. The addition of fluoride to drinking water has been widely recognized for its significant role in reducing cavities and improving overall dental health. Fluoride helps to strengthen tooth enamel, making it more resistant to the acids produced by bacteria that cause dental decay. This public health measure has led to a substantial reduction in the incidence of tooth decay, particularly in children, thereby enhancing community oral health outcomes.

While factors such as taste, color, and pH can influence water quality, they do not represent the primary aim of fluoridation. Fluoridation is focused specifically on dental health benefits rather than aesthetic or chemical adjustments to the water supply.
