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


  • 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.


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. 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!

  2. 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!

  3. 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

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

  5. 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

  6. 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.

  7. 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.

  8. 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?

  9. 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.

  10. 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.

  11. 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).

  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?
