Noticed my teeth were very smooth with the first use, like glass. Also noticed that teeth were whiter and less pale yellow after about 2 uses. Can be messy if you do not stay right above sink while brushing. Does discolored brush, so, I just leave a cup with a mixture of mouthwash and water on counter to soak while I wash my face and apply lotion. Then I simply take it out and let it dry for next time.
