My burn some: Hydrogen peroxide will actually convert to water after it released its oxygen.The teeth whitening products will burn a bit going down if you swallow some but other than transiently irritating the tissue should cause no long term problem.

No problem: There is no harm if you swallow a small amount. If you have a little sensitivity, drink some water to dilute it.

Nothing.: Assuming you don't swallow a large amount (which is called "drinking it" you shouldn't suffer any ill effect. You body makes its own hydrogen peroxide in certain white blood cells!
