What is the main benefit of fluoride in public drinking water?

Fluoride in public drinking water primarily serves to prevent dental decay in the community. This benefit is achieved through the re-mineralization of tooth enamel and by inhibiting the ability of bacteria to produce harmful acids that lead to cavities. When fluoride is ingested in small, safe amounts, it becomes incorporated into the developing teeth of children and strengthens adult teeth, making them more resistant to decay.

This preventive measure has been shown to significantly reduce the incidence of cavities over time, contributing to overall oral health in the population. Research indicates that communities with fluoridated water have lower rates of dental caries among children and adults, underscoring fluoride’s role in promoting oral health at a community level.
