A study has found that adding fluoride in water is beneficial for adults as well. It reduces tooth decay in adults of all ages, the study found.
The director of the university's Australian Research Centre for Population Oral Health, Professor Kaye Roberts-Thomson, found the effectiveness of adding fluoride in drinking water has an advantage to adults and children in promoting dental health.
Advertisement"By looking right across the Australian population, we now have good evidence that fluoride in drinking water is effective in preventing tooth decay in adults," Professor Roberts-Thomson said.
The researchers found that those adults who had more than 75 per cent lifetime exposure to water fluoridation experienced close to 30 per cent reduction in tooth decay as compared to those with less than 25 per cent lifetime exposure.
Australian Dental Association president Dr Karin Alexander said, "The ADA continues to be dismayed with the scaremongering from fringe groups that lack consideration of the scientific evidence of the significant benefits for dental health that occurs from the fluoridation of water supplies."
