This recipe uses a weird ingredient (activated charcoal) to whiten teeth. The calcium, xylitol, and coconut oil combine to maintain healthy gums and deter cavities.
Make sure the xylitol is finely ground and not coarse, grinding it in the blender or coffee grinder if necessary.
Mix all the ingredients by hand or with a blender until incorporated.
Store in a glass jar or squeeze tube and brush as usual.
Notes
NOTE: For easy blender clean-up, add a few drops of soap to the blender and then fill one-third full with warm water. Put the lid on tightly and blend on high. Dump out the suds and rinse well. Storage and Shelf Life: Keep away from very warm areas and don't allow water to get in the toothpaste jar. For longer shelf life use a clean popsicle stick or other utensil instead of dipping the toothbrush directly into the jar.
