Supplementary treatment may be necessary for the good thing about the populace. 1 these types of occasion is the fluoridation of water, where by fluoride is added to water. It's been said by the whole world Well being Business that ‘fluoridation of water supplies, the place possible, is the most effective public overall health evaluate to the avoidance of dental decay.
