Place all ingredients into the Thermomix bowl and mix 6 sec/speed 4.
Place into sealed containers (smaller ones are better as you can wash and refill once they get too wet).
Use by wetting your toothbrush then dabbing onto the surface of the paste. Brush teeth as per usual, rinsing well. It is salty!
Whitening options: Add either a teaspoon of activated charcoal powder or ground turmeric to the mixture. Both of these have excellent teeth cleaning benefits.
