I rinse with salt water then brush with Tom's Xylitol toothpaste and rinse with Spry Xylitol mouthwash.
My teeth are not only whiter but more opaque. Before they were very yellow with streaks and the bottom front teeth has brown streaks in them and what looked like cracks. I don't see those now and my teeth seem to be more of an even color density.
I've been doing OP for about a month, not not always consistantly as in every day.
