I think he means Biotene. Which sorry @Mountaindewed but that's probably not going to help your throat. Maybe worth a try but I don't think you swallow the Biotene. My dentist also recommends the xylitol lozenges that Tart Cherry Jam mentioned. I got berry flavored ones from Amazon because I don't like mint candy/gums very much. I've had a much dryer than my already dry mouth since adding Seroquel 6 weeks ago and I am just drinking water. Really cold water helps me at least for a while.

Your throat sounds like it needs a doctor to check it out.
