Define the role of Fluorine in Human Body?

Fluorine is potentially a toxic element. Its essentiality for humans is not established although the role of fluoride in providing protection from dental caries in human has been demonstrated. Fluorine (F) is a gaseous chemical element, while its ion, fluoride (F-) is composed of fluorine bound to a metal, non-metal, or an organic compound. Examples are magnesium fluoride, hydrogen fluoride, fluro/benzene fluoride. Fluoride predominates in nature and in body; it is deposited in bones and teeth. Its incorporation into tooth enamel markedly increases the hardness and resistance to decay.
