I AGREE - salt and baking soda is DA BOMB..!
I no longer use “real” toothpaste, which I consider as something for stupid suckers.
U can also sometimes use a little essential oil of Thyme (the active ingredient of Listerine and other mouth washes).
You have to dilute it in some kind of carrier oil (take your pick which one).
What ratio for salt and baking soda?
