Question to the Department of Health and Social Care:
To ask Her Majesty’s Government what is their view on the merits of reducing the concentration of fluoride in water supplies subject to fluoridation schemes from 1.0 to around 0.7 part per million, in the light of the experience of countries such as Canada, the Republic of Ireland, Hong Kong and Singapore.
Public Health England advise that there is no current evidence from monitoring data to support a variation of the target level for fluoride in drinking water.
