What is fluoride primarily known for?

Fluoride is primarily known for its crucial role in the formation of bones and teeth. It helps to integrate into the structure of hydroxyapatite, the mineral that makes up a significant portion of tooth enamel and bone tissue. This incorporation of fluoride into the tooth structure enhances the strength and resistance of teeth to decay and cavities by making them more resistant to acid attacks from bacteria and dietary sugars.

Additionally, fluoride can promote the remineralization of enamel that has been demineralized, thus playing a protective role in dental health. The relationship between fluoride and oral health is well-established, as communities with fluoridated drinking water have been shown to experience lower rates of tooth decay, underlining fluoride's importance in preventive dental care.
