DIY Teeth Whitening - Super Fast, Cheap, and Simple

My aunt told me this secret about a  year ago, maybe two now, that I think really works. Mix 1 part warm water with 1 part hydrogen peroxide, swish in mouth, and repeat a few times. When she first told me this, I thought it was nits and maybe a little dangerous (I thought it could make me sick) but if you look on the bottle, you can actually use hydrogen peroxide as a mouth wash! So I tried it. I didn't notice much of a difference at first, but after doing it a few days in a row I could really tell it was making a difference. Don't get me wrong, it's not going to give you amazing results the same way bleach would, but it's much cheaper than a kit or strips. I bought a bottle of hydrogen peroxide at my local Target for less than 60 cents. Plus, it doesn't leave your teeth feeling achy or sensitive the way bleach can. My teeth are sensitive as it is so I love that I can use this without worrying my teeth will ache for the next few days.

I like to do this at night, before bed since it helps clean my mouth as well as whiten my teeth. Since I'm going to bed, I know I won't be eating or drinking anything that could just reverse all the cleaning up I've just done. After I use it as a mouthwash, I like to take my toothbrush and dip it in the mixture and brush my teeth a bit with it, just for extra measure.

Has anyone else tried this? I find it works great since I drink coffee or tea on almost a daily basis, it lifts the surface stains that can accumulate. Let me know if you try this and what you think!
