charcoal

One night I walked up to a few of the boys, who had their backs turned, to give them a message and when they turned around I was startled to see their mouths were completely black. They were "brushing" their teeth with charcoal as it is a tradition method of teeth whitening.

So I thought I would give it a try:

Super nasty, I know.

It does work, although I think that I needed to "brush" for longer (but it really is kind of gross and messy).

The things you learn living in Zambia.
