Materials:• baking soda• Hydrogen peroxide • toothpaste(I use aim which is under $1.00 at Walmart)• water

Step 1: Step one

put a tiny bit of Toothpaste in a cup
<p>First, this small amount of hydrogen peroxide won't hurt your stomach. Second, HP doesn't hurt enamel. It's the main ingredient in all the commercial teeth whitening systems! This looks like a good Instructable to try. </p>
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.
hydrogen peroxide well safe
