Re: fasting.. now yellow teeth?

I do extended fast regularly, and have no problems with my teeth turning yellow. I do OP, and I do brush my teeth with a herbal toothpaste that doesn't have sodium lauryl, or some other chemical in it while fasting. Naturally I rinse after brushing without swallowing anything.

Contrary to what you might have read here as long as it isn't swallowed to get to the stomach, and digestive system it will not affect the fast.

If you are going to worry about something getting into the body via the skin, then you will be pretty gross from smelling because you wouldn't be able to shower with soap, and the water better be filtered to get the chlorine, and flouride out of it, all for the length of the fast. Then you will have to have washed your clothes in this filtered water also without using any soap. Don't use anything in your hair, and don't forget to wear your space suit complete with oxygen so you don't inhale any of the pollution that you are going to encounter on the way to work, or where ever you go.
