Fluoride is a key element for dental health, and its addition to drinking water since the 1950s has significantly reduced tooth decay, with a 25% decrease reported. This major public health achievement has improved oral health for many people, providing a critical layer of protection.

However, concerns have emerged about overexposure to fluoride. Today, people get fluoride not only from water but also from food, beverages, and dental care products. This has led to an increase in fluorosis, a condition that can darken or discolor teeth and make them more prone to decay if severe.

In response to this, health officials have lowered the recommended fluoride levels in drinking water in recent years to address the growing cases of fluorosis, especially among children. There is also some research indicating a possible link between very high levels of fluoride and neurological issues, but it remains unclear if these findings apply to the standard fluoride levels used in water.

Despite these worries, the benefits of fluoride for preventing chronic dental diseases remain substantial. Oral health is closely linked to other health conditions, such as heart disease and even Alzheimer’s, emphasizing the importance of maintaining strong teeth and preventing decay through fluoride.

Experts suggest that instead of removing fluoride completely, more precise monitoring of fluoride levels is needed. This approach could ensure that communities benefit from fluoride’s protective effects while also identifying and addressing areas where levels may be too high, creating a balanced solution for public health
