water fluoridation

Water fluoridation is the controlled addition of fluoride to public drinking water supplies to prevent tooth decay. Fluoride strengthens tooth enamel, making it more resistant to acid attacks from bacteria and sugars in the mouth. This public health measure has been widely supported by dental and health organizations because it effectively reduces cavities across populations, especially benefiting those with limited access to dental care. The levels used are carefully calibrated to maximize benefits while ensuring safety. Overall, water fluoridation is a cost-effective, community-wide strategy to promote oral health.
