I want to know what do you think about using hydrogen peroxide to whiten teeth?

Can burn: We have seen hydrogen peroxide burns on patients gums after they have tried to use this on teeth for whitening. It is very difficult to keep a liquid off of the gums.

Not a good idea!: While commercially available bleaching products do have hydrogen peroxide in them, it is a very low concentration. Using straight hydrogen peroxide in an attempt to whiten your teeth can cause dangerous chemical burns to your gums, tongue and throat. Do not do this!

Why bother?: Commercially available h2o2 is 3% solution--approximately the same effective ingredient as 10% carbamide peroxide--the whitener we dentists prescribe for patients. Difference is the gel we use is in a glycerin, non-dehydrating base that is concentrated onto the teeth (only) for 2-8 hours. Your 3% h2o2 solution swished around your mouth for a minute or so will not help whiten.
