It amuses no end, nay disturbs me really, how people know better than scientists who base their opinions on evidence. Evidence can come in different forms, but if you talking matters medical, medical scientists have probably conducted peer reviewed, double blind trials. Scientists are conservative folk. They are loathe to open their mouths unless they are sure and if they are not, they will qualify with lots of wishy washy words.
Where something like 97 per cent of climate scientists agree that humans have and are causing global warming, why is there still doubt? The dissenting scientists don't have good statistics to back up their anti climate change views. They, quite cleverly, manipulate data to suit their purposes.
The World Health Organisation is a well respected and conservative organisation. So when they say fluoride added to water is good, as long as it is not too much, then I believe. You can read their opinion and details here. Without any doubt it is beneficial to the health of children's teeth. Have a look at the stats for Ballarat child tooth decay, one of the last of Victoria's large cities to receive fluoride in its water.
Here is what the Australian government has to say about tooth decay in children and the benefits of fluoride, based on studies and scientific findings.
Personally, I wouldn't have a clue. I can only base my opinion on what scientists say. Scientists don't always get it right, but I would rather trust their opinion than that of an uninformed amateur.
In an absolutely disgraceful move, Queensland Premier Newman has dropped compulsory fluoridation of the water supply, leaving it to local councils with very vested interests. As always in life, it will be the poor kids who suffer the most, as they won't have access to good dental treatment and their less than great parents won't be proactive.
I may not be here in twenty years, but if you are, do have a look around the local Queensland dole offices at the jobless with no or very bad teeth and thank Premier Newman.
