So far I am using Xylitol toothpaste by Spry. But I think there is glycerin in it, and I have heard that it takes 20 brushings to remove glycerin from the teeth. I'm ready to try to soap but haven't tried it yet. I have to re-educate my family because they are going to think I'm out of my mind.
I also use the Spry Xylitol mouthwash. After OPing, I rinse with warm Sea Salt water.
In over a year that I've been doing this, I've actually enjoyed some gum regrowth. That is the thing that keeps me doing this, even though I have long ago felt other benefits from it.
I think though that OP makes me calmer. I used to be very stressed out in the mornings getting ready for work. I am no longer that way at all. OP is so zen.
