Many of us have been told since childhood that fluoride is good for our teeth. These days, a lot of people aren’t buying into the notion that it has been added to drinking water, toothpaste and mouthwash to improve our health. Some conspiracy theories claim that fluoride is meant to cause more sickness among the population, thereby increasing profits for the pharmaceutical industry and medical establishment. Others say that it affects the brain and is intended to “dumb down” the population. Looking at the world as it is today, we don’t find either theory all that hard to believe.
