Works well
Flavor Name: Peppermint, Size: 100 Count (Pack of 1)
This is a great product if you have dry mouth for any reason. It dissolves quickly though which to me for the price should last a bit longer. I know there is another product that I use for night time. They see you can last all day which you kinda have a lump in your lip. I will continue to use this product nonetheless.

They actually make my dry mouth worse.
Flavor Name: Peppermint, Size: 100 Count (Pack of 1)
I got the peppermint flavor. It’s very strong and stings, and they make my dry mouth worse. They are chalky and caused me to cough. There are plenty of cheaper and effective ones out there to choose from… that won’t go straight into the trash.
