The controversial water treatment process has been subject to heated debates whether it offers any health benefits. Current research shows that fluorinated water is more likely to benefit older people than children who are still in the process of forming teeth and may even suffer problems in the long run. Children may benefit from the said water treatment process but much is still to be seen for younger children still have baby teeth and fluorine helps in the calcification and crystallization of compounds in adults better. Another important factor is that the study may encompass the US but many countries around the world employ different treatment methods and concentrations that the results may be harder to interpret.
