Found out tonight that my painful tooth is actually split. It's amazing it's only painful when I put pressure on it.
Tried out my idea of putting a voltage across salt water in a layer of oil floating on it, trying to separate out the chlorine and elemental sodium. It didn't work; nothing happened at all. I would have thought a 6V differential would be enough to draw the ions through the oil, but nope.
