Fluoride is important for the mineralisation of bone and teeth, and most known for its role in oral health and prevention of dental caries. The small amounts of fluoride provided through toothpaste or fluoridated water offer considerable protection against dental caries. WHO estimates that dental caries still affects 60-90% of schoolchildren worldwide and the majority of adults in most industrialised countries – and is the most widespread non-communicable disease (NCD). When consumed in optimal amounts in water and food, and used topically in oral hygiene products, fluoride increases tooth mineralisation and helps to reduce dental sensitivity.
