DIY All-Natural Herbal Mouthwash for Healthy Teeth & Gums

Looking for a homemade natural mouthwash recipe that not only freshens breath but improves oral health? This DIY All-Natural Herbal Mouthwash for Healthy Teeth & Gums is exactly what you’re looking for!

Ah, there’s nothing that compares to that fresh and clean feeling of mouthwash!

It doesn’t matter if you’ve been stuck on a bus with busted AC all day next to an old Italian man with garlic seeping out of every pore (been there), swish a little mouthwash you’ll feel like a whole new you in an instant!

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. 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.

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

  3. 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?

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

  5. Hi Nadia, thank you for this post+recipe. When I click on the links for the oils it takes me to the website ‘’?
    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?

  6. 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?

  7. Hi Nadia
    Another question please
    Are the TRACE MINERAL DROPS to be added to the mouth wash recipe like your toothpaste recipe?

  8. 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?
