I do like how clean my teeth feel
Still waiting to see the effects. Maybe a little whiter or is it greyish instead of yellow?  I do like how clean my teeth feel.  Don't like the black all over the sink that requires a full wipe down after each brushing. I also need to make sure my face and mouth are fully clean before leaving the bathroom because of the black that is left around the mouth and between the teeth. A good rinse and face wash after use is recommended, then take that towel and wipe down the sink! Gums were a little sore at first but that has resolved after about 6 days of use now.
