So the secret is out on Black Seed Oil. I was fascinated to find it in a toothpaste, let alone in a fluoride toothpaste. The feeling I get after I brush is one that I used to only have after a professional polishing. Now I have this sensation every time I brush. Kudos to SprinJene for having the courage to mix a little science, a little nature, and some ingenuity to make a better toothpaste.
