mouthwashNot all mouthwashes are created equal, and some use more questionable ingredients than others. One way to freshen your mouth without the worry is to create your own mouthwash using essential oils.

You can easily make your own mouthwash that is free of chemicals, perfumes, preservatives, artificial colors, and more with two simple ingredients—water and essential oils—which can be just as beneficial (if not more) than chemicals used in traditional mouthwashes.

Try this simple and cost effective mouthwash recipe for a clean, refreshed, and healthy mouth.


10 drops of essential oil(s)

2 cups distilled water

16-ounce dark glass bottle


1. Add water and essential oils into glass bottle. You’re done!

2. To use, shake first and take a small sip of mouthwash. Swish around your mouth and gargle for 30 seconds. Do not swallow.

There are many essential oils you could use in your mouthwash. Below are a few suggested oils you could use, by themselves, or by combining two or more to make a blend. Be careful when using Cinnamon essential oil as it can be irritating if too much is used. Start with 1 drop and gradually increase if desired. Also, did you know you can use dōTERRA’s On Guard® Natural Whitening Toothpaste can be used as a mouthwash as well?

  1. Why can’t you swallow? That’s confusing to me. I would think it would do you some good if you could get past the mental anguish of swallowing your mouthwash.

  2. I’m so excited to try this! Right now, I use a drop of OnGuard oil each morning, but this will make it easy and perfect for my whole family! Thank you so much for sharing!

  3. My grandmother was a herbalist. She gave us a little bit of fresh peppermint leaves after we had dinner with garlic. It worked great. So this all makes sense to me!

  4. It’s good to be aware that everybody can make their own care products.

    So many products contain chemicals that hurts us and we don’t even know that. Or probably know that, but we don’t know what other solutions do we have.


  5. We created our own mouthwash long before this was published – our favorite oils to use are On Guard, Peppermint, Myrrh and Thyme.

  6. Just know that boiling water can actually make some things more concentrated in your water like fluoride. Boiling does not necessarily mean “clean”!

  7. Hey just as a heads up, if you leave in an area with fluoridated water, boiling it only increases the fluoride content in the water. you can check here at Thanks for the awesome recipe.

  8. Claire, when you make you mouthwash do you combine all four oils together in your mouthwash or use them separately?

  9. UV rays can effect essential oils. The darker glass bottles are to help keep the sunlight out and protect the essential oils. You can use clear glass bottle if they are stored in a dark place.

  10. Will essential oils in my drinking water or mouthwash dissolve the glue that holds my dental porcelain veneers or harm the surface to them at all?

  11. Can u use dark blue bottles? I have a few of them!
    Can I use old OnGuard foaming hand wash bottles?
    Save the landfill!!!

  12. Are there any plastic bottles that can be use? I would really like to make this for myself, but also my kids. I really don’t want glass bottles around my small kids. The mouth wash would mostly be for my older kids but they all share a bathroom so my younger ones could certainly get to it. Thanks!

  13. Water does not dilute oil so if you wish to use an EO “mouthwash” I suggest mixing with coconut oil and swish this way to prevent and burns or any type corrosion of mouth tissue.

  14. I’ve been trying DIY toothpaste for a month and it works pretty well. Then I think ‘why not trying self made mouthwash now?’ Can’t wait to try this recipe. Thanks for sharing!
