Are there any health risks associated with water fluoridation?
Many studies have looked at this topic. A U.S. committee on environmental health that has reviewed many of these studies has concluded that there is no link between cancer in humans and fluoride levels. And although some studies suggest that increased bone fragility may be linked to higher rates of exposure, we don’t know yet for certain as there are too many factors involved. Like many natural substances, fluoride can be harmful in excessive amounts. Even table salt can be harmful if taken in large quantities. However, we are typically exposed to acceptable amounts of fluoride, even though it is available from a number of sources.
