Water companies will be forced to add fluoride to Britain's drinking supplies under moves by MPs to prevent tooth decay in children. By the age of five, nearly two-thirds of children in some parts of the UK have at least one rotten tooth.
There is overwhelming evidence that fluoridation, supported by dentists, can dramatically reduce the spread of tooth decay.
However, critics argue that it should be up to parents to cut sweets out of their children's diets and supervise teeth-brushing, rather than forcing the nation to drink chemically spiked water which may carry health risks.
Tomorrow MPs will push to amend an unrelated water Bill, currently due before Parliament, to make fluoridation compulsory where local people vote for it.
