I have 3 versions of toothpaste and I have been using the flouride free version for 18 months. I LOVE it. I will never use store bought again. Granted, it took a small window of adjustment to not have a candy flavor in my mouth, but my mouth never feels fresher longer than using my handmade version. My teeth are whiter and the hygenist commented on it, until I told her what I do. Then it was all, "well you really need flouride," blah blah blah. I told her I had xylitol in it that does the same thing without the bad side effects, and she poo pood it because it wasn't enough to do anything and "nothing remineralizes teeth." However, at the end of my kids appt, they were ready to push a remineralizing toothpaste at $18 bucks a tube on me that had what? Xylitol. Needless to say, I take everything this country's medical professionals say with a grain of salt and an eye on my wallet. Nothing homemade is good enough until it makes them money.
