To ask Her Majesty's Government, further to the Written Answers by Earl Howe on 7 February (WA 18-19) and 24 November (WA 275), (1) whether they share the concerns about dental fluorosis that led the Republic of Ireland to lower the concentration of added fluoride in mains water to 0.7 parts per million in 2007, and (2) what relevance the use of more fluoride supplements by the population in the United States has to the incidence of dental fluorosis in the United Kingdom.

We are not aware of any evidence from the Republic of Ireland to show that levels of dental fluorosis were unacceptable when water supplies were fluoridated at 1 part per million. We cannot see any relevance between the use of more fluoride supplements by the population in the United States and the incidence of dental fluorosis in the United Kingdom. We are awaiting publication of a research study into the prevalence and aesthetic acceptability of dental fluorosis before considering whether the use of a 1 part per million concentration here should be reviewed.
