I cant speak on mag pulsers steralizing root canals but I can say that when I was drinking food grade(35%) h202 at 25 drops per 2 cups of water I had some type of debri(looked like a pimple) pass through the inside of my gums at the base of my root canal/crown.
I believe it killed anything bad that was in my gums or roots of teeth....not to mention whitend my teeth!
Ive noticed that drinking h202 will make your body kill or reject what is not suppose to be in you...
taste nasty though..
