The key ingredient in this homemade mouthwash is hydrogen peroxide. A lot of dentists actually recommend small amounts of hydrogen peroxide as a mouth rinse to help in killing bacteria in your mouth and even helping to prevent cavities.

And you probably already know that most teeth whitening agents contain varying amount of hydrogen peroxide. This is an added side benefit of this homemade mouthwash…it also helps whiten your teeth!

You can find hydrogen peroxide very inexpensively at any drug store. It costs between $1-$2 for a big brown bottle of it. To make your own minty mouth wash, mix:

  • 1/4 c. hydrogen peroxide
  • 1 c. water
  • Approximately 8 drops mint extract

I mixed mine together in a mason jar. You need to use this up in a couple of days because the hydrogen peroxide eventually turns into water if you let it set out in the light too long. If you store it in a dark place or even in the brown bottle the peroxide came in it will make it last longer.

Adding flavoring to your mouthwash is optional. I actually used it without the flavoring for quite awhile. It just depends on if you can stand the flavor of the peroxide. If you do add flavoring, make sure that it is food grade extract and not essential oils that are not meant to be ingested. Make sure to check your labels. I used a mint extract that is used for flavoring food.

Hydrogen peroxide is also used for treating any kind of sore in your mouth. It disinfects the sore and helps it heal faster. If you look at the list of ingredients on oral rinses you buy at the store, most of them contain hydrogen peroxide in them. (The store-bought rinses just have a lot higher price tag on them).

Use this mouthwash as you would any mouthwash, and make sure not to swallow it. Peroxide is not harmful as long as it is not ingested.
