Fluorine chemistry is integral to modern lithium-ion batteries, with lithium hexafluorophosphate serving as a key electrolyte salt to facilitate ion transport. In dental health, fluoride, a derivative of fluorine, strengthens tooth enamel by incorporating into minerals and promotes remineralization, leading to recommendations for its use in toothpaste and public water fluoridation.
“Fluorine plays a central role in powering modern electronics, as today's lithium ion batteries regularly rely on fluorine chemistry.”
“Fluoride, which is just a negative fluorine, can become incorporated into tooth minerals, making enamel more resistant to acid attack.”
“The centers for disease control states that fluoridation at recommended levels reduces tooth decay and cites an approximate 25% reduction in cavities among children and adults.”
