THIS is to register my dismay and to protest at the addition of fluoride into our drinking water (LET, December 23). It is unthinkable. A poison given indiscriminately.

A health trust should have better responsibility and promote 'health' in other ways, such as diet and less use of sweets and junk foods for all.

I hope you have enough response to sway opinion against adding this poison to our water supply.
