Coconut oil is anti-bacterial, anti-fungal, anti-microbial & destroys tooth-decaying bacteria. Baking soda is a mild abrasive that helps maintain (or restore) ph balance. And it has whitening capabilities. Together they make a powerful team. Mix coconut oil & baking soda until you get a consistency you like. And if you want to get fancy with it you can add an essential oil like peppermint or grapefruit.
Use this combination to make:
+Toothpaste-make a single-use batch or a month's worth, it will last you a little bit.
+Quick Face Mask or Scrub (think DIY microdermabrasion)
+Foot Scrub-use with a brush or wash rag on rough spots
