The addition of fluoride to public water supplies has been recognized as one of the top ten greatest health achievements of the 20th century by the U.S. Centers for Disease Control. This addition has led to a significant reduction in dental caries in both adult and pediatric populations, especially in areas with lower income households. Studies have shown that fluoride in the water supply can reduce dental disease by more than 25%, particularly benefiting those who do not have access to regular dental care or fluoride toothpaste.
Fluoride is a naturally occurring mineral that has been added to public water supplies for over 70 years, resulting in improved dental health outcomes for both children and adults. However, the rise in popularity of bottled water, which often does not contain fluoride, has led to an increase in dental caries in children who rely on bottled water over tap water. Some bottled water products designed for children have started adding fluoride to address this issue.
In addition to its dental health benefits, fluoride in drinking water has also been linked to improved outcomes for individuals with otosclerosis, a condition that can cause conductive hearing loss. Studies have shown that individuals with otosclerosis living in areas with fluoridated water have better hearing outcomes compared to those in areas without fluoride in the water supply.
While there have been concerns raised about the safety of fluoride in drinking water, multiple organizations including the National Research Council and the American Cancer Society have found no direct link between fluoride exposure and cancer. Overall, the presence of fluoride in public water supplies has had positive impacts on dental health and, to a lesser extent, on hearing health for certain individuals.
