Mike, thanks for the info. What is selegen? Is that anything like the Biotene Oral Balance jel that is applied inside the mouth? And in your personal experience - does this seem to help a lot? I will let me husband know, and perhaps he can ask the doc about that. The Ora jel is OK - but it does tend to wash away pretty fast after you drink something or just even after swallowing, so if there's anything better - we'll look into it. Thanks again.
