Die Vorteile für die Zahngesundheit durch die Zugabe von Fluorid zum Trinkwasser sind heute möglicherweise geringer als vor der allgemeinen Verfügbarkeit von Fluorid-Zahnpasta. Die Cochrane-Studie ergab, dass der Nutzen der Fluoridierung seit den 1970er Jahren, als fluoridhaltige Zahnpasta breiter verfügbar wurde, zurückgegangen war.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

The dental health benefits of adding fluoride to drinking water may be smaller now than before fluoride toothpaste was widely available, a review suggests.

Researchers from the universities of Manchester, Dundee and Aberdeen assessed evidence from 157 studies comparing communities that had fluoride added to their water supplies with communities that had no additional fluoride in their water.

The review found that the benefit of fluoridation had declined since the 1970s, when fluoride toothpaste became more widely available.

“Most of the studies on water fluoridation are over 50 years old, before the availability of fluoride toothpaste. Contemporary studies give us a more relevant picture of what the benefits are now.”

Results from studies conducted after 1975 suggest that water fluoridation schemes may lead to slightly less tooth decay in children’s baby teeth.

“Given that the benefit has reduced over time, before introducing a new fluoridation scheme careful thought needs to be given to costs, acceptability, feasibility and ongoing monitoring.”

A while back there were claims that governments wanted to add fluoride to water to create a docile and obedient society and there were claims that fluoride is a key ingredient in Prozac. The closest I’ve seen to anything like this is a study that says fluoride creates anxiety in adolescent mice.

My parents both have had major teeth problems and they’ve even drinking unflorinated well water for decades.
