when I was a kid I wore braces. I also tested batteries with my tongue. One day I decided to connect a 9V battery (the one with the poles side by side) with my braces, to see what will happen. One pole on the upper side, the other on the bottom. There was a big shock, my field of vision became bright white for a split second, and I never tested batteries with any part of my face ever again.
