In a glass measuring cup, mix together the baking soda, sea salt, and xylitol.
Add fractionated coconut oil and essential oils, stir until well combined.
Mix in your filtered water, and stir until the solids have dissolved (warm water will dissolve the solids better than cold water).
Pour into your glass storage bottle using your funnel
Place lid on your bottle, shake mixture before each use to ensure the essential oils remain distributed.
To use, Pour a small amount into a small glass, swish for 30-60 seconds. Then gargle to clean the back of your mouth, and spit into the sink.
Notes
You can use any combination of essential oils of your choice. (Make sure the brand you use is safe for internal use - see my recommendations in the post). Some oils are hot (like clove and OnGuard), so you will want to use less of those. I would use a maximum of 5 drops of a hot oil in this mouthwash. Use a citrus or mint oil for the remaining drops of essential oil. Feel free to omit ingredients if you don't have them, or don't wish to use them. The xylitol is optional for sweetening and may help prevent tooth decay. Fractionated coconut oil adds additional anti-bacterial qualities, but is not necessasry.
