I wrote to Andreas Moritz when I was beginning a total dental revision. He suggested the Kinokatara pads. I bought a ton of them and would like to say they have helped. I don't know. However; I was a little disheartened when I read that he said the pascalite clay was more effective that the pads. It costs $7.00 per night with the pads and I have had them on everynight for 2 solid months. They say most people see the brown/black lessen after 30 days. Every morning the pads are like tar. So this is not true or I am VERY toxic. I found cheaper ones called Takara and bought them. After wearing them one night, my husband said I smelled like the Hayman Fire (we live in Colorado). It was disgusting. Then I wrote Spirit and asked about heavy metal toxicity and he said do 10-20 more liver flushes to get rid of the metal. Now this I BELIEVE!!
