HC Deb 11 January 1977 vol 923 c444W
22. Mr. Marten

asked the Secretary of State for Social Services what is the latest estimated cost of the fluoridation of water supplies.

Mr. Moyle

An estimate of the total cost cannot be provided since capital and running costs vary from one health authority's area to another according to the nature of the water supply system. However, experience has shown that fluoridation is the most effective and economical means of protecting the whole community against dental decay.
