Great tasting lozenges that actually work and offset dry mouth. They have a cool, refreshing taste. I've had dry mouth issues for years and found these to be the best and prefer the lozenges over Biotene's other products. I carry a sleeve with me at all times and leave one in the car. I really love this product.

Work great for instant relief of dry mouth.

They work great for a dry mouth. I like them a lot more than the Biotene Dry Mouth Spray or mouth wash. They taste good & relieve the super dryness that occurs due to my low electrolytes. Plus, I can carry them in my purse or to the gym.
