Here is a very good video on the fluoridation of our water and from a dentist's point of view. I have been concerned for some time about this issue, ever since I read that fluoridated water causes gingivitis. Since then I have used toothpaste that does not contain fluoride. But I still brush my teeth with unfiltered, fluoridated tap water. Now that will change also.
Please watch this video, especially if you have infants or children under six years of age.
Also, visit Dr. Mercola's website for more information on this danger (you will see the video there also, but scroll down the page for Dr. Mercola's input).
