That will be all you need in order to achieve this amazing remineralizing toothpaste at home. Here's what you need to do:
Mix very well the calcium powder with diatomaceous earth, baking soda, and xylitol powder into a bowl.
Then, you can add the coconut oil gradually, about one part at a time until you get a thicker consistency. The consistency will depend entirely on you and how thick you like your toothpaste to be.
Next, add the mint essential oil to get the most amazing fresh flavor. You could also go for peppermint orange essential oil, another one of my favorites.
Lastly, simply store this paste into a small glass container, I find it hard to transfer into a paste tube. Regardless, I also thought that it is easier using it directly from the glass container. I simply dip a clean toothbrush into it and start using it as I would normally do.
