Making homemade toothpaste

If you don't know that fluoride is poison don't believe me do your own research or just continue to put your trust in big government because they have never lied right? Even if you don't believe it, it doesn't hurt to use toothpaste without all those nasty chemicals. Our ancestors didn't have Crest or Aquafresh nor did they need it. Straight up baking soda did the trick.
