Did a Harvard dental professor, who moonlights as a consultant to Colgate, suppress evidence linking fluoride to bone cancer in children? A study done by a PhD candidate at Harvard Medical School was hidden away in their library until someone from the Environmental Working Group and the Fluoride Action Network discovered a copy in 2001. It's conclusions were startling.

It's an old video but worth watching again and ask yourself would you be convinced the professor is being open and honest.
