Easy Natural Mouthwash Recipe

Let’s face it, there’s nothing worse than bad breath. From morning breath to coffee breath to garlic breath, you don’t want to be the person making your friends’ and colleagues’ eyes water all day long.

Bad breath can be embarrassing and there are a lot of different reasons you may be suffering from it. Bad breath can stem from what you eat and drink, from smoking, certain medications, having a cold, issues with your gums and a variety of different medical conditions.

The most common reason for bad breath though, according to the National Health Service, is simple poor oral hygiene.

“Bacteria that build up on your teeth – particularly between them – as well as your tongue and gums, can produce unpleasant-smelling gases. These bacteria are also responsible for gum disease and tooth decay… any food trapped between your teeth will be broken down by the bacteria and may be responsible for bad breath.”

So, the easiest way to combat bad breath is to practice good oral hygiene. Easy right?

There’s one problem, though. Many mouthwashes and toothpastes contain ingredients that can be harmful to your health and even the environment.

Many common mouthwashes contain large amounts of alcohol, which according to Best Health can dry out your mouth and cause bad breath. Chlorhexidine is another ingredient often used in mouthwash. It can alter your taste buds and is not recommended for long term use.

If you’re an avid mouthwash user but you don’t like the sounds of those ingredients, don’t sweat it! We’ve created a mouthwash recipe that’s sure to keep your mouth clean and your breath fresh without any of the scary stuff.

Easy DIY Mouthwash


1 tbsp Perfect Press® Coriander Oil
32 drops tea tree essential oil
16 drops peppermint essential oil
1 cup distilled water
3 tbsp baking soda (optional)

You will also need:

  • Measuring spoons (teaspoon & tablespoon)
  • A 1-pint mason jar  


  1. Put the distilled water, essential oils and coriander oil into your jar. Screw on the lid and give it a good shake.
  2. Add baking soda, if using it.
  3. Put the lid back on and shake it again.
  4. Use about a tablespoon and a half to rinse with after brushing. Swish for about a minute. Don’t forget to spit!
  5. Keep the lid screwed tightly on the jar between uses. Shake before each use.

Note: It’s very important that you swish and spit because of the fact that there are essential oils in this recipe. Mouthwash should never be swallowed, even if it’s natural.

Some benefits of these ingredients

  • Tea tree oil: Tea tree oil has powerful antibacterial and antifungal properties. It will kill bad bacteria that can cause problems in your mouth. Natural Living Ideas cites studies done by the Tea Tree Group of Australia, that show “that a range of oral bacteria, which is responsible for tooth decay, was susceptible to tea tree oil even at a low dilution. Tea tree oil is especially effective for those who are prone to fungal or bacterial oral infections when used as a natural mouth rinse.
  • Peppermint oil:  Peppermint oil has antimicrobial properties too, and can freshen bad breath, plus it adds a nice minty flavor, which many of us associate with a clean mouth. According to Body Unburdened, peppermint essential oil “is extremely effective at killing anaerobic bacteria, the type of bacteria that thrive in a low oxygen environment such as the mouth, and can cause gum disease.
  • Baking soda: While this may seem like a strange ingredient to some, many toothpastes include baking soda in their formulations. Baking soda can help combat bad breath and neutralize the acids found in your mouth, but according to Livestrong, it can also help “break the bonds that stain molecules on the teeth. This makes the stains appear less noticeable.”
  • Distilled water: BreathMD tells us that tap water can contain “chlorine, mercury, fluoride, nitrates, and may even contain some carcinogens such as chromium-6.” Using the purest water possible is a good idea when you’re making your own mouth rinse. If you have an osmosis filter on your tap, you can go ahead and use tap water but otherwise, stick with distilled.
  • Perfect Press® Coriander Oil: Cold-pressed coriander seed oil is a great long-term solution for getting rid of bad breath and can even prevent canker sores. That’s not all it can do, though.
