For the past few weeks have experienced dryness and sore tongue, also strange taste in my mouth. It is not localized to any one area; went to my dentist who noted slight discoloration (darker) on left side of tongue. Suggested rinsing with biotene several times daily, and rinsing with water and opened capsule of proboitic 2x daily. This hasn't changed anything. Feels as tho it has something to do with my saliva after eating something;
almost a salty taste.
