Whether fluorosilicic acid and sodium silicofluoride will be used to fluoridate the water supply if fluoridation goes ahead and what advice…

The consultation document, Towards Better Oral Health in Children, published on 24 September, seeks views on a range of possible measures to improve children's oral health, including fluoridation. Questions relating to the implementation of any particular option are not being considered at this stage. Section 1 (4) of The Water (Fluoridation) Act 1985 provides that the increase of fluoride in the public water supply may be effected only by the addition of one or more of the following compounds of fluorine: hexafluorosilicic acid; disodium hexafluorosilicate. All products and processes used in the treatment of water are approved at either EU level or by the UK Committee on Products and Processes for Use in the Public Water Supply.
