You can adjust the essential oils or add other natural ingredients to suit your taste and oral care needs. With just a few ingredients and minutes, you’ll have a fresh, effective mouthwash ready to use anytime.

Ingredients

  • 1 cup distilled water – Base liquid to keep the mouthwash clean and pure
  • 1 teaspoon baking soda – Neutralizes acids and freshens breath
  • 1 tablespoon aloe vera juice – Soothes gums and promotes healing
  • 10 drops peppermint essential oil – Provides refreshing flavor and antibacterial properties
  • 5 drops tea tree essential oil – Natural antiseptic to fight bacteria
  • Optional: 5 drops clove essential oil – Adds extra antibacterial and analgesic benefits

Equipment

  • Measuring spoons – For accurate ingredient amounts
  • Measuring cup – To measure water precisely
  • Glass mixing bowl or jar – For mixing ingredients
  • Small funnel – To transfer the mouthwash into your container
  • Glass or BPA-free plastic bottle with tight lid – For storing the mouthwash
  • Whisk or spoon – To mix ingredients thoroughly

Instructions

  1. Start by pouring 1 cup of distilled water into your glass mixing bowl or jar. Distilled water is important because it’s free from impurities that could affect the mouthwash quality.
  2. Add 1 teaspoon of baking soda to the water. Baking soda helps neutralize acids in your mouth and freshens breath. Stir gently until it dissolves completely.
  3. Mix in 1 tablespoon of aloe vera juice. Aloe vera is soothing and supports gum health. Make sure to use pure aloe vera juice rather than gel to avoid clumping.
  4. Drop in 10 drops of peppermint essential oil for a refreshing, minty flavor. Peppermint also has natural antibacterial properties that help fight bad breath.
  5. Add 5 drops of tea tree essential oil. This powerful natural antiseptic fights bacteria and helps maintain oral hygiene.
  6. If using, add 5 drops of clove essential oil. Clove oil is known for its pain-relieving and antibacterial effects, great for sensitive gums or occasional toothache.
  7. Whisk or stir the mixture well until all ingredients are fully combined.
  8. Using a small funnel, pour the mouthwash into your storage bottle. Close the lid tightly and shake gently before each use to re-mix any settled ingredients.
  9. To use, swish about 1 tablespoon of homemade mouthwash in your mouth for 30 seconds to 1 minute, then spit out. Do not swallow.
  10. Store the mouthwash in a cool, dark place and use within 2 weeks for maximum freshness and effectiveness.

Tips & Variations

“Always perform a patch test when using essential oils to ensure you don’t have sensitivity or allergies.”

If you want to customize your mouthwash, here are some ideas:

  • Swap peppermint oil for spearmint or eucalyptus oil for different refreshing flavors and antibacterial effects.
  • Add a few drops of lemon essential oil for a bright, citrusy note and extra antibacterial power. Avoid if you have sensitive teeth as citrus can be acidic.
  • For whitening benefits, add a pinch of activated charcoal powder but use sparingly and rinse thoroughly afterward.
  • Use coconut oil as an alternative base for oil pulling benefits combined with the essential oils.

Remember to shake well before each use since natural ingredients can separate over time.
