Following a horrific photograph of my not-quite-pearly whites, I searched the internet for cheap home tooth whitening methods, and came across the idea that normal bar soap could not only whiten my teeth, but was actually better for my teeth than my normal toothpaste. Is there any truth to this?
I imagine it would NOT taste very good.. Brushing your teeth every other day with baking soda is a home remedy that definitely works. It won't give you bleached teeth, but it will be cheap and will help gently scrub off surface stains.
