Fluoridation of public water supplies in this country at the optimal level of one part fluoride per million parts of water has been shown to be a safe, effective and an efficient public health measure in reducing dental decay. Fluoridation is used as a public health measure in Ireland and in some parts of England, Switzerland and Spain. The United Kingdom Government is committed to extending water fluoridation to all major towns and cities in England, Wales, Scotland and eventually Northern Ireland.
There is no credible evidence linking water fluoridation to the long list of health effects attributed to it by anti-fluoridationists. The research work of international agencies investigating possible health effects is being continually monitored and any recommendations of these bodies will be reflected in Department of Health policy concerning fluoridation.
