Natural Homemade Mouthwash

Refreshing, bacteria-preventative, alkalizing, all-natural mouthwash.
Prep Time 5 minutes
Author Libby


  • 2 cups filtered or distilled water warm
  • 1 T. baking soda
  • 1/8 tsp. salt I use pink Himalayan salt
  • 3 drops peppermint essential oil
  • 1 drops OnGuard essential oil or Germ Fighter from Plant Therapy


  • Warm the water. You don't need it hot. Just warm enough to easily and quickly dissolve salt.
  • Add baking soda and salt to the water. I used a blender bottle, and it was a lot faster than stirring to dissolve.
  • Add the essential oils and combine as before.

To use

  • Shake, stir, or swirl the solution before use.
  • Use as you would a normal mouthwash, but rinse your mouth with water afterwards, and limit use to 4 times a week.**


Using a saltwater rinse too frequently can weaken the enamel on your teeth.
Do not swallow the rinse. Large amounts of highly concentrated saltwater can be harmful, and essential oils should not be ingested, either.
