WHO report on fluoride in drinking water

The World Health Organisation has published a new report aimed at helping communities with an excess of naturally occurring fluoride in their water supplies to avoid health problems.

The report emphasises that "low concentrations are good for teeth, but excessive concentrations can lead to debilitating disease, such as skeletal fluorosis, which has devastated some communities". It notes that "in China alone, more than 10 million people are estimated to suffer from skeletal fluorosis".
