Fluoride is primarily used for what benefit?

Fluoride is primarily used to benefit teeth because it plays a crucial role in dental health by promoting the remineralization of tooth enamel, making it more resistant to decay. This mineral helps to repair early stages of tooth decay and inhibits the growth of bacteria that cause cavities. The addition of fluoride in water supplies and dental products, such as toothpaste and mouth rinses, significantly reduces the incidence of dental caries (cavities) in populations.

Although fluoride is often discussed in the context of overall health, its most significant and well-researched impact is specifically on dental health, rather than on bone health, digestion, or heart health. While fluoride does have some interactions with the skeletal system, its primary function and proven benefits lie in strengthening teeth and preventing dental issues.
