Queensland, the only state in Australia that does not fluoridate its waters, is ranking as it relates to the oral health of its children.

A new study on the dental health status of children in 44 countries around the world revealed that kids in Uganda, Africa have better oral health than their counterparts in Australia.

According to a report by the Australian Institute of Health and Welfare, almost half the country's six-year-olds still suffer cavities - an average of two - in their baby teeth. More than four in ten 12-year-olds had cavities in their permanent teeth.

The same report confirmed that Queensland and the Northern Territory (including Tasmania) registered the highest number of cases of children with decaying and missing teeth as against other areas in the country, particularly in the Southern and Western portions.

"Children from areas where drinking water contained negligible fluoride had poorer dental health than did children from areas with either naturally or artificially fluoridated water," the report said as quoted by news.com.aus.
