The history of this episode is especially revealing about the way the public has become utterly disenfranchised in a world where bureaucrats arrogantly assume they know what is good for the rest us. Although many people believe they already have fluoride in their tap water, only around six million actually do. Most of them live in the West Midlands and the North East, where artificial fluoride was first added about 40 years ago and around half a million are in areas where fluoride occurs naturally in the water. Successive governments have always wanted to increase coverage, believing it would be good for dental health. But the water companies did not want to fluoridate the supply, fearing they would be sued. They also did not consider public health to be their responsibility.
