I spotted this blog post on Coconut Mama about a more natural method for teeth whitening. What really caught my eye is that it uses Activated Charcoal to do so.
"Open one capsule of activated charcoal into a small bowl. Wet your tooth-brush and dip it into the charcoal. Gently brush teeth with charcoal. Swish the charcoal around in your mouth for a few minutes after brushing. Rinse out your mouth and brush with your teeth with your normal tooth paste. Do this as often as you like."
I know activated charcoal is great, but I've never considered it for this use before. What are your thoughts on this? Think there could possibly be some damaging side effects?
