The RITA Meter in Spokane, Washington

With metal/ amalgam fillings, mercury is the biggest concern, but copper is close behind in toxicity and amount. The brain operates on 7 to 9 nano-amps and a metal filling provides up to 100 or more micro-amps. Natural teeth with no fillings frequently emit a reading of 1 to 4 micro-amps of current just because our bodies are electrical entities. It is important to note that a reading of 4 micro-amps is considered the maximum allowable electrical output. The significant difference in these readings is comparable to touching a 9 volt battery and sticking your finger in a light socket as far as the brain is concerned. Since the upper teeth are less than 2 inches from the brain, it is of concern that adding this much excess electrical activity into the brain has the potential of creating mis-directed impulses to the brain.
