My understanding on this is that you find peroxide included in all of your teeth whiteners that are sold and we have toothpaste that has baking soda, so I went full strength with both to get the best effect.

I swish with H2O2 before brushing with baking soda. I also add two or three drops of Dr. B-----'s liquid soap (peppermint) on top of the baking soda. Once in a blue moon I'll put a drop of oil of oregano on my toothbrush such as after I've been sick or if I feel like I'm trying to catch a cold/flu or something. My teeth have really whitened up since I've been doing this. I've also noticed that the sensitivity has totally gone away too. I haven't used toothpaste since, don't want the poison fluoride. Been doing this for approximately six months now. Dentist appt is coming up. We'll see how that goes.
