Have you tried PerioSciences hydration products. The dental gel has an antioxidant as well as xylitol. You put a bead between the lips and gum, top and bottom. Keeps the lips to the back taste buds on the tongue lubed. ProVantage Dental Gel is the product name.

Dr. John xylitol candy does an incredible job also. 2 mg/piece. [/quote]

Assuming you tried both, how does the provantage gel compare to the biotene oral balance gel?
