Fluoride in Water

Fluoride in public water supplies is a proven public health measure that helps reduce the incidence of dental cavities. Adding fluoride to drinking water, a process known as water fluoridation, has been shown to prevent tooth decay by about 25% in both children and adults. This benefit occurs because fluoride strengthens tooth enamel, making it more resistant to acid attacks from plaque bacteria and sugars in the mouth. By helping to repair the early stages of tooth decay, fluoride can prevent the need for more extensive dental treatments down the line.

Water fluoridation is also cost-effective, especially for communities with limited access to dental care. Studies show that for every dollar invested in fluoridating water, approximately $38 is saved in dental treatment costs. This preventive measure reaches people of all ages and socioeconomic backgrounds, offering a universal benefit that does not rely on individuals’ behavior, such as brushing habits or diet.

Furthermore, fluoride in water supports equitable health, as low-income populations tend to have higher rates of dental issues but may have limited access to dental care. By providing continuous protection against cavities, water fluoridation improves oral health across populations, reducing disparities and fostering healthier communities.
