It's All in Your Head

Mercury is one of the world’s most poisonous substances, and yet dentists routinely use it in amalgams to fill our teeth. Forty years ago, Dr. Hal Huggins questioned this practice, and now legions of dentists, researchers, and citizens are adding their voices of concern.
 
It’s All in Your Head looks at past research on mercury toxicity and dental amalgams as well as current scientific findings that can no longer be ignored. It describes the possible effects of mercury toxicity, including multiple sclerosis, Alzheimer’s disease, Hodgkin’s disease, Chronic Fatigue Syndrome, and virtually all autoimmune disorders.
 
Written in easy-to-understand language, It’s All in Your Head explodes the claim that mercury amalgams are safe. If you think your worries are all in your head, you may be right.
