Ingredients

  • 1/2 cup distilled water – the base liquid for the mouthwash
  • 1 teaspoon baking soda – natural teeth whitener and odor neutralizer
  • 1 teaspoon 3% hydrogen peroxide – gentle bleaching agent and antiseptic
  • 2 drops peppermint essential oil – for fresh breath and flavor
  • 2 drops tea tree oil – natural antibacterial properties
  • Optional: 1/4 teaspoon xylitol powder – sweetener that also helps prevent cavities

Equipment

  • Measuring spoons – for accurate ingredient amounts
  • Small mixing bowl or cup – to combine ingredients
  • Glass or BPA-free plastic bottle with lid – to store the mouthwash
  • Spoon or small whisk – to mix the ingredients thoroughly
  • Funnel (optional) – for easy transfer of mouthwash to bottle

Instructions

  1. Start with distilled water. Pour 1/2 cup of distilled water into your mixing bowl or cup. Using distilled water ensures the mouthwash remains pure and free from impurities.
  2. Add baking soda. Measure out 1 teaspoon of baking soda and add it to the water. Baking soda helps neutralize acids in the mouth and gently whitens teeth.
  3. Mix in hydrogen peroxide. Add 1 teaspoon of 3% hydrogen peroxide to the mixture. This mild antiseptic helps break down stains and kills bacteria.
  4. Stir thoroughly. Use a spoon or small whisk to mix the ingredients until the baking soda has completely dissolved.
  5. Add essential oils. Carefully add 2 drops of peppermint essential oil and 2 drops of tea tree oil. These oils provide a refreshing taste and potent antibacterial benefits.
  6. Optional sweetening. If desired, add 1/4 teaspoon of xylitol powder to sweeten the mouthwash naturally and support dental health.
  7. Combine and transfer. Stir the mixture again to blend all ingredients well. Using a funnel, pour the mouthwash into your storage bottle and seal tightly.
  8. Store properly. Keep the mouthwash in a cool, dark place or refrigerate for up to one week. Shake gently before each use.
  9. Use with care. To use, swish about 1 tablespoon in your mouth for 30 seconds, then spit out. Avoid swallowing the mouthwash.

Tips & Variations

Tip: Always use 3% hydrogen peroxide, which is safe for oral use in small amounts. Never use higher concentrations without professional advice.

Tip: If you have sensitive gums, reduce the hydrogen peroxide amount to 1/2 teaspoon and increase the water accordingly.

For a different flavor profile, try substituting peppermint oil with spearmint or clove essential oil, which also have antibacterial properties.

If you prefer a stronger whitening effect, consider adding a pinch of activated charcoal powder—just be cautious as it can be messy and abrasive if overused.

Remember, this mouthwash complements regular brushing and flossing but shouldn’t replace professional dental care.
