My first choice to make my mouth fresh and clean
Size: 16 Fl Oz (Pack of 1)
I have a lot of trouble sleeping and using the sleep apnea machine dries my mouth. This mouth wash is my favorite for feeling clean and refreshed. It really helps with that dry mouth I get from using the sleep apnea machine

Really solves dry mouth with a great taste and convenience.
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.

Long lasting
Keeps the mouth moisturized even an hour after use. No sugar, better for overall oral health.
