THE STATE government is considering legislation that would force councils including Murrumbidgee and Carrathool to add fluoride to the water supply.
Opposition health spokesman Andrew McDonald tabled the legislation last week, saying fluoride was one of the most cost-effective health interventions and it was time for the state government to step in.
The Area News revealed on Friday that Murrumbidgee and Carrathool shires were among 4 per cent of the state that does not add fluoride to the drinking water supply.
The Chief Medical Officer for NSW Dr Kerry Chant has since released information directly contravening Carrathool Shire mayor Peter Laird's reasons for denying fluoride to residents under his care.
"There is no valid scientific or health evidence that appropriately managed fluoridation of drinking water supplies will cause negative health effects," Dr Chant said.
The health department also declared even more councils around NSW were adding the natural substance to the water, suggesting the Carrathool and Murrumbidgee shires would be in the final 2 per cent of NSW without it by 2015.
Griffith dentist Dr Jonathon Munro said the water supply was the best way to take in fluoride and it significantly reduced tooth decay.
"As far as the teeth are concerned, the studies have shown that fluoride decreases decay by up to forty per cent," Dr Munro said.
"The rate of decay, missing teeth and filled teeth is much higher in children that don't have access to fluoride."
Dr Munro went on to dispell another of Cr Laird's arguments that fluoride toothpaste is enough, provided people brushed every day.
"When fluoride is in the water, you get a low and constant dose which is much more beneficial to your teeth than fluoride tablets which can cause fluorosis which gives you blotchy teeth," Dr Munro said.
"Fluoride toothpaste will help if you don't have fluoride in the drinking water but brushing twice daily only gives you four minutes exposure to it, whereas drinking it in your water mean it will recirculate around your body and it will come through your saliva, which is much more beneficial."
The mayor of the Murrumbidgee Shire, Phillip Wells, declined to comment.
