It is a known fact that the presence of fluoride in water we drink or use for brushing out teeth is a controversial issue. Many of the experts point to negative effects of fluoridated water and argue for removing this chemical element from our drinking water. Studies have shown that fluoride in water leads to a variety of problems with our digestive system, including even such serious health condition as stomach ulcer. Besides, fluoride overdose which can possibly be a result of using fluoridated water, can have serious negative effects on our bone structure, leading to a variety of bone health related problems. In addition to the mentioned facts, excessive fluoride in water can be especially dangerous for little children whose body is still developing and can be really very sensitive to any chemical imbalances in the daily diet or drinking water quality.
On the other hand, fluoride is a chemical vital for our excellent dental health. It is a component of almost all dental care products like tooth pastes or mouthwashes because it helps prevent most of the known dental diseases and dental conditions. According to the most recent findings of an international scientific team, those people who use fluoridated drinking water have lower risks of tooth decay, one of the most common dental health conditions which usually results in quite serious dental problem including tooth loss. The research group based at the Australian Research Centre for Population Oral Health (ARCPOH) at the University of Adelaide’s School of Dentistry, found some strong evidence to the fact that those people who use fluoridated water have better dental health since fluoride in water can play a role of a very effective instrument for tooth decay prevention. At that, as the study leaders underlined, the mentioned benefits can be clearly traced in adult people rather than in kids and teenagers.
For the study, the scientists analyzed extended data collected on over 3800 people of Australia continent aged 15+. The participants were asked to answer a number of questions about their current dental health, their dental care habits, and also the water they usual use. Professor Kaye Roberts-Thomson, one of the study leaders and the director of ARCPOH at the University of Adelaide, said that the main idea was to focus mainly on adult participants since the effects of fluoride in water on kids are more or less researched. “We’ve known for some time that fluoridated drinking water can prevent tooth decay in children, but this is the first time that research has conclusively shown this in an adult population,” he said. After analyzing the data and looking closer at the results, the scientists came to the conclusion that those adult people who used fluoridated water for about 75 per cent of their lifetime enjoyed up to 30 per cent more effective tooth decay prevention compared to those who used fluoridated water for less than 25 per cent of their lifetime.
Thus, longer exposure to fluoridated water brings to more significant benefits, the Australian researchers are convinced. In addition to that, the scientists came to one more quite interesting conclusion. “Even those people who were born before water fluoridation existed have since received some benefit in their lifetimes,” Professor Kaye Roberts-Thomson said. The study leader underlined the importance of the findings of his scientific group on the background on the unfolding public controversy related to the effects of fluoride in water on our overall and dental health. He said that the discovered links should contribute to supporting using fluoridated water by all adult Australians and people around the world. The findings of the scientific group of the University of Adelaide were published earlier this month in the Journal of Dental Research, and if you want to find more information, see the detailed report about the study in this webpage.
