Another product has hit the market to help with dry mouth, called XyliMelts (ORAHEALTH Corporation). These are mint or mint-free discs that adhere to the cheeks or palate and slowly dissolve over 1 to 6 hours. This product is especially useful for comfortable sleeping. It appears they are only available for purchase from online vendors. Let me know what you think if you try it. I have received good feedback from a similar product called OraMoist.
