But most store-bought mouthwashes are filled some pretty unhealthy ingredients.

Let’s take a look at the ingredients of one of the most popular mouthwashes out there:

Active Ingredients:

Thymol (0.064%) [ORGAN SYSTEM TOXICITY], Eucalyptol (0.092%), Methyl Salicylate (0.060%) [DEVELOPMENTAL/REPRODUCTIVE TOXICITY], Menthol (0.042%)

Inactive Ingredients:

Water, Alcohol (21.6%) [ORAL CANCER], Sorbitol Solution, Flavoring, Poloxamer 407, Benzoic Acid [ORGAN SYSTEM TOXICITY], Sodium Saccharin, Sodium Benzoate [ORGAN SYSTEM TOXICITY], FD&C Blue 1 [ORGAN SYSTEM TOXICITY; has actually been banned for use in other countries]

Let’s take a deeper look at the alcohol. Not quite sure why this is considered an “inactive ingredient” since there is so darn much of it in there and certainly for its germ-fighting properties.

There is now sufficient evidence to accept the proposition that developing oral cancer is increased or contributed to by the use of alcohol-containing mouthwashes…

It is the opinion of the authors that, in light of the evidence currently available of the association of alcohol-containing mouthwashes with the development of oral cancer, it would be inadvisable for oral healthcare professionals to recommend the long-term use of alcohol-containing mouthwashes. — McCullough and Farah, Australian Dental Journal


Time for a safer alternative, huh?

This DIY natural mouthwash gives you that fresh and clean feeling plus benefits the teeth and gums.

The salt and calcium-magnesium powder help to strengthen and remineralize teeth while the essential oils freshen breath, fight bacteria, and reduce gum inflammation.


DIY All-Natural Herbal Mouthwash for Healthy Teeth & Gums

Ingredients:

  • 1 cup filtered water
  • 1 teaspoon Real Salt or pink Himalayan sea salt (rich in minerals; inhibits bacteria growth; helps heal cuts and reduce gum inflammation)
  • 1 teaspoon calcium magnesium powder (helps remineralize teeth)
  • 2 drops spearmint essential oil*
  • 2 drops cinnamon essential oil*
  • 2 drops peppermint essential oil*
  • 2 drops clove essential oil*
  • 2 drops myrrh essential oil* (myrrh is not an herb, it’s a resin, but I’m including it in here!)

*After doing the research, I consider these essential oils to be the best essential oils for healthy teeth and gums. If you’d like, you can instead just use one or a few rather than all 5.

Directions:

Add all of your ingredients to a glass bottle (I used an old ACV bottle!), shake it on up, and ta-da! You now have your very own DIY all-natural herbal mouthwash for healthy teeth & gums!

I use this mouthwash twice a day, morning and night after brushing with my DIY all-natural whitening + remineralizing toothpaste. While the salt and EOs inhibit bacteria growth, to play it safe I make a new batch weekly.

  1. Thakns so much for this recipe. I’ve never really used mouth wash because of these ingredients but now I’ll just make my own. I also heard that neem oil and powder was good for teeth. Do you not recommend it? I tried it once as a mouth wash and it was really bitter.

  2. I have some cal-mag tablets…can I smoosh them to powder and use this? I hate to buy more what I already have.

    Thanks for the recipe…searching for a appropriate container now….

  3. Hi there,
    Why won’t you add a pdf link or something, so readers can download the recipes more easily?
    Thanks.

  4. Would replacing the water with boiled cinnamon water be a good idea too? Like would it make the mouthwash more effective?

  5. Methyl salicylate is wintergreen oil and thymol is thyme oil. Those are the two main active ingredients that actually fight gingivitis in mouthwash… and you take them out, so this would not actually qualify as a useful mouthwash. Technically, according to the ADA, mouthwash cannot stop cavities, but can be used to treat slight gingivitis. The remaining oils you use a primarily flavoring agents according to MSDS, except clove oil. I’m a dental student who does research on essential oils as part of her doctorate in dentistry. In fact clove oil (aka eugenol) is more hepatotoxic than thymol and methyl salicylate. We use it to sedate inflamed pulps as it is incredibly powerful stuff. Sometimes people use it at home to quell tooth pain, but we do not recommend it due to its high toxicity potential unless we explicitly tell you or we apply in the office it as an temporary filling material. In the end, flossing / brushing is a million times more effective at preventing gingivitis and periodontitis than mouthwash anyways. Mouthwashes really are just a marketing gimmick except for prescribed Chlorhexidine rinses.

  6. I’ve been using your toothpaste for a while now and recently decided to try this mouthwash. I don’t think mouthwash is really all that necessary, especially if using such a great toothpaste, but I do like using it! it’s just a refreshing final rinse and helps get rid of any last particles of the toothpaste! However, I’ve made 2 batches so far, and I can only use it maybe twice before I start seeing green mold on the bottom of the jar! How do you make yours last a week!? I can barely get it to last more than a day! Would keeping it in the fridge make it last longer? Is there another ingredient I could add to help keep the mold away? I really love this and hope I can figure out a solution! Thanks!

  7. Oh no! That really just shouldn’t happen: coconut oil is a natural antibacterial as are a number of these essential oils. Are you adding water to the mixture? That is the only way wold would form. Or if your container is dirty.

  8. It’s the mouthwash, not the toothpaste, that is giving me the mold problem! The container I’ve been using for the mouthwash is clean….any ideas?

  9. Hey Lindsay: You are getting green mould because a small amount of water is getting into your jar for your toothpaste. Coconut oil spoils like most oils when water in any amount is introduced. If you are dipping your wet toothbrush into the jar as an example this might happen. Try using a clean tiny spoon or baby spatula to keep the toothpaste moisture free 🙂

  10. Hi Nadia,
    Thanks for yet another fabulous recipe! I bought some of the Trace Minerals to make my bodyunburdened toothpaste with, and I have a lot extra. Is it ok to put some of the trace minerals into my mouthwash as well?
    Thanks!

  11. Interesting formula on mouthwashes. Out of necessity (could not afford the dental work), I slowly developed a mouthwash formula to stop my tooth pain and strengthen my gums. I used a formula based on minerals. I suspect the high PH of the formula helped lower the bacteria count and the minerals helped build back up my enamel and gum tissue such as ligaments. For the most part I avoided sugar. I concluded that the root of my problem was teeth grinding. The teeth grinding was creating cracks in my teeth that were letting bacteria grow more quickly.

    It takes a while for the pain to go completely away. I found out the more and the longer I rinsed the better the results. Severe cavities with severe pain can require long rinse times.

    Today, I still use the mineral and oil formula, but only sparingly. If I notice tooth pain coming on, for instance when I have been eating a lot of ice cream, I increase the mineral density, frequency and length of rinses, and every time it seems to do the trick.

    I was concerned about toxicity of the minerals. All of the minerals I use are minerals that are considered nutrients and have RDA minimum values.

    The link to the general formula can be found here.

    You don’t have to really mix the formula, I just chew mineral tablets with some cinnamon and ginger for flavor and then use a tablespoon of coconut oil to mix it in my mouth.

  12. Hi Nadia,

    Thank you for this blog. I just made the recipe.

    One thing that I need to know is, should I still make a new mouthwash after a week if I keep it refrigerated? If not,What will be the shelf life when refrigerated?

  13. Hi, Carleen. Great, I hope you enjoy it! Honestly, these things aren’t a hard-science so I can’t say for sure. But I’d say a couple weeks. Another way to prevent bacterial growth is to pour the mouthwash into a small glass (so you’re not getting bacteria from your mouth on the bottle).

  14. I’m loving your blog <3 but I am concerned about the comment that was posted regarding toxicity of clove oil… have you found out any new information regarding safety? I have found conflicting information — some sources stating clove oil is healing and beneficial if used in small quantities and other sources stating that you should never use it except under a dentists supervision due to the toxicity issues. Thanks for any info updates.

  15. Hey, Kelly. Good question and thanks for prompting me to look into it again. I’ll need to do some more research on it and get back.

  16. Hi there, LOVE this mouthwash, thank you for sharing. Whenever I make a batch, not all the salt and powder dissolves,there’s always a layer of it that stays at the bottom of the jar. Would boiling the salt and calcium in the water help it fully dissolve or is this a normal feature of the mouthwash that I should let be?

  17. I have the same issue with the Real Salt – just the very pink salt remains, and I always assume it’s minerals that just don’t dissolve! You could try boiling the salt (I wouldn’t boil the calcium) and see if that helps, but I just give the bottle a shake before each use.

  18. You realize Thymol is simply a component of Thyme oil correct? Thyme is considered one of the essential homeopathic herbs and Thymol is what gives Thyme it’s unique scent and flavor.

    Thyme has been long used and revered for it’s ability to heal gums and thus without it you don’t have a real mouthwash that will provide any additional benefit over using a re-mineralizing toothpaste.

    What I use for mouthwash:
    1/2 cup Distilled water brought to a boil
    Handful of Fresh Thyme
    Few Sprigs Fresh Mint (spear/ginger/etc.)
    Few Sprigs Basil
    Few Whole cloves and cinnamon

    Pour the boiling water over the herbs and spices and let it stew for a while.

    Once the tea is made I strain off the herbs, add a spoonful of xylitol (which alkalines your gums helping fight gingivitis) and pink sea salt. I then mix the tea up with a cup of Silica water (water that I dissolved Diatomecous Earth in and let sit overnight so the D.E. builds up at the bottom, then pour from the top).

    This makes enough mouthwash for about a week. I simply re-make it weekly. It would likely spoil if left more than a week anyways.

  19. I look forward to receiving good health e-mails Holistic recipes and body maitence is important. I look forward to your opinion. Sincerely Mrs.Lois Weiner

  20. Hi. Where do u buy ur oil’s from. I can only seen to find aromatherapy oils, is it the same? Thanks

  21. Hi Nadia, I have a question about the amount of water – can’t wait to make this mouthwash it sounds wonderful. But how much is 1.5 cups in ml?
    many thanks, Jem

  22. Hi, I’m on a medication that would prevent me from using this mouthwash, because of the calcium magnesium. Is there anything else that can be used to re-mineralize teeth in place of the calcium? I realize that it is technically not supposed to be swallowed, but I would rather not take any chances. Alternatively, I am just going to try the mouthwash without the calcium powder, until such a time that an alternative can be found. I’m so enjoying your website! Thank you!

  23. Hi Autumn! You can simply omit it and use the sea salt and mineral drops, both of which are great sources of minerals. Also, I would do some research about how to support your diet for remineralization. Good luck!

  24. Hello
    Just made my first batch of your mouth wash recipe-excellent!! My question is: Do you rinse at all with water after or would that negate the positive affects?
    In appreciation
    Scott Belanger

  25. Hi Nadia
    Another question please
    Are the TRACE MINERAL DROPS to be added to the mouth wash recipe like your toothpaste recipe?
    In appreciation
    Scott Belanger

  26. Another question please
    I always start my morning with scraping my tongue upon waking AND I also oil pull with coconut oil- do you like oil pulling?

    In appreciation
    Scott Belanger

  27. Hi Nadia, thank you for this post+recipe. When I click on the links for the oils it takes me to the website ‘affiliateshop.com’?
    Where do you purchase your oils? There are so many vendors, and I’ve bought many brands in the past. Just wondering who you use?
    Thanks..
    Jo

  28. Going to try this and the toothpaste. And see what happens before my next Dental visit coming up in October.
    Thanks a bunch.

  29. Do you have a non-spicy recipe for Mouthwash? Non mint, non cinnamon, using other oils and ingredients that are good for teeth and gums?

  30. What’s a good replacement for the peppermint eo? My boyfriend is deathly allergic to peppermint.

  31. Wow this actually doesn’t taste bad! I used 3 drops of each oil instead of 2. My teeth feel great and my breath is minty cinnamony fresh! Thank you for this great recipe. Will use this from now on.
