Great solution for nighttime coughing.
Size: 40 Count (Pack of 3)
My dental hygienist recommended this when I told her I used a cough drop during the night bc I coughed. Obviously cough drops are not good for your teeth, and I found these serve the same purpose! They stick to the roof of your mouth & provide moisture all night long. So glad I found out about them. Pleasant taste - lasts all night.

Lasted about an hour
Size: 40 Count (Pack of 1)
Today I used my first mint flavored melt, it lasted for exactly an hour. I didn’t have super high expectations for this to last 8 hours, but want to see if it would improve my overall enamel and prevent cavities. I was hoping it could help my night time dryness from a chronic stuffy nose and sleeping with my mouth open. I placed it upper molar area, but I think it’s good even still.

No more dry mouth in the mornings
Size: 40 Count (Pack of 1)
Finally waking up without dry mouth. I do have to use 1 on each side, and they’re hard to stick on, but honestly worth it. I’ve been getting cavities from dry mouth due to medications, and I’m so glad I’ll be able to prevent them from getting worse.

Amazing product!
Size: 40 Count (Pack of 1)
This is something that actually works! I am amazed at these dry mouth melts! They work great and I am very happy after trying multiple products that never seemed to work. The only complaint I would have is that they dont last all night for me, so I just use 2. but I am very satisfied with them and how good they work.
