SMILE!!!!!!!!!!!!!!

Thanks to dhara http://captainchemistry.tumblr.com/ I now know what makes teeth whiteners  whiten your teeth. Hydrogen peroxide and carbamide peroxide. When this is put on your teeth it attacks two layers of your teeth the enamel and the dentin. See this is why i don't use teeth whiteners. They can really hurt you teeth, and i like my teeth and plan to keep them for a while.
