While dissolving plaque the hydrogen peroxide and baking soda mixture also dissolves enamel, but it still makes your teeth white so if you're that desperate for white teeth then knock yourself out.

H2O2 is pretty safe here. Make sure to spit it all out and rinse youre mouth well though. It can cause lip irritation so before use I would advise coating them with chapstick prior to use. Might have to mix some of this up later :)

Only in small amounts, and even then it can cause severe stomach upset.
