Xylimelts Sensitive
I was sensitive to the regular Xylimelts after a few months use. Painful gums and hives inside my lips and cheeks. The sensitive version immediately corrected the problem and I’ve been using them without issue for nearly a year. The product is a lifesaver for drymouth that occurred when I was sleeping.

Best that I have found for dry mouth.
These are the best for dry mouth at night. They mostly stay stuck. I say mostly because I have had a few come apart. I think that was my fault.

A Great Product!
These tablets are inspired! I use them every night with my cpap. The back of each tablet has a coating that, when moistened, is easily glued to a back tooth to slowly dissolve while sleeping. Works like a charm! These would be good to use when speaking publicly, too - no more performance dry mouth. You really can't tell it's there once it's glued in. The minty flavor is there, but not overwhelming. I am never without my Xylimelts!

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!
