Fluoridated Water: Still a Valuable Tool, but Benefits May Be Diminishing

Tooth decay remains a significant public health concern worldwide. For decades, adding fluoride to community water supplies (CWF) has been a cornerstone of dental health strategies. However, a recent Cochrane review (titled “Water fluoridation for the prevention of dental caries” written by Tanya Walsh and et. al., 2024) suggests that the benefits of CWF may be less pronounced today than in the past, particularly in developed countries where fluoride toothpaste is widely used. The Review’s Findings: The review analyzed 157 studies comparing tooth decay in children living with fluoridated water and those without. Why the Change? The authors attribute this shift to the widespread use of fluoride toothpaste. With fluoride readily available through oral hygiene products, the incremental benefit of CWF may be less pronounced in modern populations. Important Considerations: The review emphasizes that these findings do not negate the … Read more

Fluoride in Water Does Not Lower Intelligence

An interesting article titled “Community Water Fluoridation and Intelligence: Prospective Study in New Zealand,” appears in the 2014 edition of the American Journal of Public Health by Jonathan M. Broadbent and et. al. The researchers set out to explore whether or not having fluoride in water that one drinks when they are young and age effects the developing brain negatively. The researchers followed nearly all aspects of the health and development of around 1,000 people born in Dunedin in southeast New Zealand in 1972-1973, up to age 38. The researchers compared IQs of those who grew up in Dunedin suburbs with and without fluoridated water. Furthermore, if one used fluoride toothpaste and tablets the researchers used this in their analysis. The researchers focused on fluoride expose during the first five years of life as this is a critical period of time … Read more
