My recipe has become a bit of a blend of other people's ideas + trial and error + taste and preference = end result.
My research lead me to Primal Organics Dirty Mouth tooth powder, that I did purchase a trial size and used it to see how I liked it. I wasn't thrilled with the dry powder approach so I took the list of ingredients (charcoal, variety of clays, baking soda, and the EOs ~ peppermint & I add clove also), and I choose not to add any sweetener mostly because I don't add so much EOs that I need to sweeten it, I only add a few drops of each because I make small(ish) batches.
My recipe is roughly equal parts (teaspoons if you want to start small) of:
*Charcoal (I don't remember which kind, but there are technically 3 types and I got the type that is best for oral uses),
*Kaolin clay
*French green clay
*Bentonite clay
*baking soda
*Arrowroot powder (optional, I just added it to my last batch, can't say I've noticed a significant difference
)
*EOs (few drops of each, remember this is a small quantity batch, you don't need much)
*Coconut oil (I use raw unrefined, from the grocery store) add just enough to make a paste, whatever consistency you like. I lean towards a thicker consistency because you won't need much, it will spread through your mouth as you brush.
I know some dentists say NO GRIT, but the other side says you need the grit to clean and polish. Do you know why your dentist needs to scrape away tartar buildup when you go in for cleanings? Because commercial toothpaste doesn't have grit in it to clean it off your teeth
Ever since I've been using my mixture, I only have 3 little deep corners (thanks to crooked teeth) that need a pick to reach the tartar
My teeth don't hurt, I don't have hot/cold sensitivities, I don't have any gum issues. My dentist is amazed because I really have a lackadaisical approach to dental care. And I have had no new issues with my teeth since going natural
I'm not making any claims, just saying this is what is working for me ~ and I did have to get used to it ~ and I did a lot of trial and error (in small batches), and I'm still experimenting (for example: the arrowroot; and sometimes additional EOs).
**Other pros: truly neutral breath (no bad breath, no "toothpaste breath"); doesn't give me a funky after taste when I eat or drink something after brushing (you should still wait at least 30 minutes after brushing before you eat or drink).
I apologize for the lengthy response but I tried to touch all the bases
if you still have questions, I will do my best to answer them
