Review on Biotene Oral Rinse Mouthwash: The Ultimate Dry Mouth Treatment and Breath Freshener in Refreshing Fresh Mint - 33.8 fl oz by Jamie Simpson

When I sleep my jaw opens and I breathe through my mouth, especially when my nose is stuffy. I've been using Biotene's dry mouth formula for a while. It's not perfect, but I haven't found a product that's perfect yet. I use it at night and wake up with it. It does not completely eliminate dry mouth during sleep, but reduces its intensity. Dry mouth seems to get worse when I'm not using it. Of course I don't use it exactly as directed, it should be used to soothe an existing dry mouth or regularly throughout the day to prevent it. When used as directed it works great. The solution has a very soothing sweet mint flavor and provides relief to an already dry mouth. I'm no dental expert, but the sweetener is xylitol, which I know is chemically incompatible with the bacteria that normally cause tooth decay.
