IAN Upton, chairman of Bolton Against Fluoride group (June 21), is up-to-date and spot-on with his comments about the dangers of fluoridation.

We must have the right to choose which chemicals we want in our bodies. If the gate is open to add fluoride, then what else will go in next year? The outcome could well be horrendous.

Guy Harkin (June 27) notes there are 41 national organisations promoting the harmless and beneficial effects of fluoride.

Perhaps these 41 national bodies also promoted Thalidomide? We are a democracy we have the right to choose.
