You will need:
5 tsp. baking soda
1/4 tsp. salt
10 drops peppermint essential oil
5 tsp. vegetable glycerin
Directions: Mix all ingredients together. you may need to adjust the amount of glycerin to get just the right consistency. Store in a small jar. I usually use an old yeast jar that I washed out. Great way to resuse what you have. I just dip my toothbrush into the paste and brush away. Minty fresh and chemical free. Also a lot cheaper than commercial toothpaste.
Note if you have sensitive teeth and gums then add about 25 drops tincture of myrhh and 10 drops of essential clove oil to this recipe. The myrhh helps with inflamation and the clove oil is a natural anesthetic.
