Al Oshlack, Lismore. I am most upset at the alleged assault of Lismore mayor Jenny Dowell. I have issues with Cr Dowell over the way she has handled the fluoride issue and the North Lismore Plateau development, but totally abhor this angry outburst which has besmirched the integrity and sincerity of those residents who oppose the fluoridation of our water supply.

Carmel Liertz, Lennox Head. It’s truly tragic that the small majority of Rous Water councillors and the state health department are so determined to push fluoridation, when evidence has been gathered over many decades about fluoridation and as such is considered 'an outdated practice that most of the world countries don’t even do'.

Rob Watson, Myocum. John W Travis in his letter to the Echo re fluoridation writes that we should look at the facts. OK let's look at the evidence he cites in his letters.

Trevor Robertson, Upper Crystal Creek. I am nonplussed by the debate in northern NSW concerning the fluoridation of water.
