No one ever mentions Biotene any more. I know that this mouthwash has changed its formula a bit, but it still the best way, for me, to cleanse my palate. It's worth a try. I rinse with this just before I brush teeth 2-3 times a day. And, sometimes when I get a bit of a rough tongue or taste overload, I will rinse with this and fir up another pipe. YMMV
