I also had stains on my teeth which I suspect are caused by green tea consumption. The new toothbrush seems to have removed these stains too. Richard I am curious as to what toothbrush you are using. I bought an Interplak at the high recommendation of a friend, and after using it for three weeks, had a lot of stains on my teeth from tea consumption. Switching back to a manual brush removed much of the stains, but not all. The only dental hygeine habit that I had changed was the instrument I used to clean my teeth. I followed the instructions for the toothbrush, moving it in the proper manner and brshing at least 2 minutes (usually about 4). Perhaps that's just not the right electric toothbrush for me. I don't like the stains, but refuse to give up green tea and herb teas (raspberry and peppermint stain, too).
