Is 3% hydrogen peroxide strong enough to affect bacterial balance in your mouth...?



Jul 4, 2012
I'm thinking of using it twice a day, in the morning and before going to bed, rinsing for 1-2 minutes...

H2O2 gets rid of mucous, cold sores, and keeps flossed teeth from
getting infected, but is clearly not strong enough to affect the
natural balance of bacteria in your mouth.
I don't think there is much risk ordinarily, I don't advocate
routine rinsing with peroxide. It does sometimes change the color of
oral mucosae. It's also not a very good antiseptic.
