Australia - Study backs fluoride benefits

................People born between 1970 and 1990 had an average of 4.5 teeth affected by decay, compared more than 24 teeth for those born before 1930.
But the news was not all good, Prof Slade warned, with most people still susceptible to dental disease."A total of 25 per cent of Australians have cavities, one in five has gum disease and another 15 per cent have experienced toothaches in the last 12 months," he said.The survey also revealed that only 44 per cent visited the same dentist for an annual check-up, with a direct correlation between dental attendance and levels of oral disease.
About 30 per cent said they avoided check-ups because of the cost, but people with private dental insurance were more likely to get regular care.
Aboriginal people and other disadvantaged groups were the most likely to have dental health problems.
Prof Slade said the findings supported Australia's National Oral Health Plan which promotes broad fluoride use, particularly for the elderly, low income earners and indigenous Australians.

I should have thought the findings supported an improved free dental service. now no longer available anywhere except perhaps Cuba.
