Understanding Fluoride and Its Role in Dental Health
Fluoride, a negatively charged ion of fluorine, plays a crucial role in dental health by preventing cavities. It typically exists in compounds such as sodium fluoride, which replaces hydroxyapatite in tooth enamel, strengthening it and making it resistant to decay. The naturally occurring mineral is found in various environmental sources, including soil and water, and historically has been associated with reduced mortality from dental infections. The connection between fluoride and improved oral hygiene became evident in the early 20th century when researchers observed lower tooth decay rates among residents in areas with naturally high fluoride levels, prompting further investigation into its benefits.
