Really helpful for dry mouth.
Scent Name: Berry, Size: 100 Count
These really work. I wear a CPAP and my mouth was so dry I was waking up with my tongue stuck to the roof of my mouth. They stick well so no worry of swallowing it during the night. I like the berry flavor.

A Miracle for dry mouth!!
Scent Name: Berry, Size: 100 Count
I don't know what I would do without this product. I suffer from severe dry mouth from my medications and xylmelts have been a miracle for me. I buy them regularly and cannot live without them
I sleep comfortably with them in my mouth and they help beyond belief.

Slim profile, stays anchored all night (Berry flavor is great!)
Scent Name: Berry, Size: 100 Count, Scent Name: Berry, Size: 100 Count
I rely on these nightly to combat dry mouth, and they deliver exactly what is promised. The adhesion mechanism is impressive—once placed against the gum, the disc stays securely anchored for a full 6–8 hours without shifting, allowing me to sleep without interruption.
The profile is ideal; the discs are incredibly slim and unobtrusive, so you don't feel like you have a bulky object in your mouth while trying to fall asleep. Despite being so compact, they pack enough moisture to last until morning. The Berry flavor is mild and soothing, making it a perfect bedside companion. Highly recommended.
