Dental amalgam is mainly mercury and silver. The amount of mercury released to the system by fillings is extremely small and not hazardous, but some people react to the name alone, not to any credible hazard, as they do with radioactivity, radiation or nudity.

Low-level mercury poisoning is characterized by fatigue, headaches, lack of concentration and hair loss. These are hardly distinctive symptoms, being much like those caused by work, or a falling stock market.
