3% Hydrogen Peroxide

  1. Jan 17, 2006 #1
    I've been advised by my dentist to use 3% Hydrogen Peroxide as a mouthwash, to help clear bacteria out from underneath the gumline. Although I trust his judgment, I couldn't help but notice that hydrogen peroxide is poisonous. I'm sure this is safe to do for the short term, as it's used as a topic antiseptic all the time, but I'm wondering about possible long term effects of this, so any information or opinions would be helpful

    edit: and yes, I know I'm not supposed to swallow the stuff

    thanks

    I wouldnt be too woried about 3% H2O2....its the 30% you need to watch out for.

    From http://en.wikipedia.org/wiki/Hydrogen_peroxide ,
    And the MSDS, http://www.jtbaker.com/msds/englishhtml/H4073.htm ,
    So as you said, just dont swallow any of it and you should be in good shape.

    I am an American living in New Zealand. Hydrogen peroxide 3% costs about 5$ for 125ml here. Is there any cheap easy way to make a couple liters of the stuff?

    Depends on the planned use. You may try to buy 30% stuff and dilute it tenfold, but I would not do that if you need 3% solution for medical use, as you don't know what is in the 30% technical solution - it may contain harmful stabilizers or contaminants. But it can be perfectly safe for other tasks.
