Introduction
Fluorine is one of the most reactive elements with high electronegativity and the second-highest electron affinity. It has an oxidation number of -1 and exists as either inorganic fluorides or organofluorine compounds [1,2]. F- exposure in humans occurs majorly from consuming water contaminated by F- from various natural and anthropogenic sources such as volcanic eruptions, mining residues, industrial effluents, phosphorus fertilizers, and certain domestic activities [3,4].

On 23 September 2021, the four UK Chief Medical Officers (CMOs) stated 'there is strong scientific evidence that water fluoridation is an effective public health intervention for reducing the prevalence of tooth decay and improving dental health equality across the UK'.1
Water fluoridation started in the USA in 1945 and is currently practised in about 25 countries. In the USA, 74% of the population receives fluoridated water, with over 200 million people having their water fluoridat
