7 thoughts on “is baking soda or hydrogen peroxide better for bad breath?”

  1. Hydrogen Peroxide will kill the bacteria in your mouth and bacteria do cause bad breath, but they can come from the throat and/or stomach too.

    Baking soda would be a poor choice.

    Also remember to dilute the perioxide and to spit it out.

  2. Hydrogen peroxide is good if there is an infection. There is another chemical available which I can’t remember the name of but I think it is related to sodium hypochlorite (bleach) which was originally used to reduce the odor of garbage and was found to be very effective against bad breath. I’m sure you’ll find it if you search the internet. It is commercially available.

  3. i mix soda with the peroxide and brush twice a day…makes your mouth fresh and your teeth very shiny…

  4. Soda works well.Gargle your mouth with water in which salt and soda bicarb have been added.More useful remedies at
