As my right hon. Friend is aware, I am a very part-time dentist and I am also a supporter of the British Fluoridation Society. Probably the very biggest reason for children attending hospital for general anaesthetic is to extract decayed, rotten, abscessing teeth caused by dental caries. Fluoridation of the water supplies is a very effective means of prevention. Does he support fluoridation of the water supplies, and what can he do to actively promote it, because, at the moment, it is in only 10% of our supplies?
