Perfect for dry mouth!
I suffer from extreme dry mouth due to sleep apnea and side effects of medications. I used to gargle with mouthwash made for dry mouth before going to bed but it would wear-off by morning.. I’d awaken with severe cotton mouth! What’s worse is my mouth gets dry during the day when I’m out and can’t gargle. It’s so bad I can barely talk! Thank goodness for these melts!! They are GREAT! They stick easily to your gums or roof of your mouth and stay there! They slowly dissolve over night and I wake up without cotton mouth! I keep some in my purse for daytime. They’re better than lozenges or hard candy because they’re discrete. You don’t want to give a speech and be seen sucking on a candy! I use them so often that I was THRILLED to find them in the 100 quantity bottle at a lower price than I could find anywhere else! Protect your oral health and get these pleasant mint tasting melts for your dry mouth!

No more dry mouth at night!
These stick to your gums and keep your mouth moist all night. This makes it easier for me to sleep. I got them on the recommendation of my dental hygienist and have been getting better checkups since I started using them. It keeps your mouth moist which retards the growth of germs.

Great product
These are excellent. They work very well and help ensure a good night's sleep without a dry mouth. Ans the taste is good, unlike Berry Smoothie which is absolutely disgusting.
