Evidence of Harm chronicles the lives of three ordinary Americans who become reluctant health advocates after suffering from the devastating effects of hazardous mercury vapors during routine dental procedures. The film presents a haunting portrait of a dental industry all too willing to turn a blind eye to science while placing profits and politics ahead of the 120 million Americans currently implanted with toxic mercury dental fillings.

This documentary came to realization when, Randall, the films creator received news that his father had been diagnosed with Alzheimer’s Disease. Randall immediately set out on a personal journey to find the cause for what might be contributing to this devastating illness. While scouring the scientific literature, a connection was found. There were numerous studies indicating mercury (a known neurotoxin) was a causal factor in the onset of Alzheimer’s disease… and the largest source of mercury in the general population had been repeatedly shown to come from mercury dental fillings. After discovering this information Randall set about making a documentary on the hazards of dental mercury fillings to patients, staff and the global environment.
