I read about this all over the internet. Strawberries have malic acid so they whiten your teeth if you mash them and coat them on.
Thing is, this article says it damages your enamel if you do it more than once per week. Damn, that's infrequent! And I heard the process takes forever too, like months and months.
How long does the whiteness last? How long does it really take to get a noticeable color change?
Is this really worth it? Does it wear down your enamel little by little?
I'm looking for a natural alternative to strips and powders that's easy, cheap, and creates no damage...
