Great to keep in purse for when I have a dry mouth.
Flavor Name: Tart Cherry, Size: 3.85 Ounce (Pack of 1)
I suffer from dry mouth due to diabetes, and these help when I’m somewhere I can’t get to a water bottle quick enough.

They suck!
Flavor Name: Tart Cherry, Size: 3.85 Ounce (Pack of 1)
Never again. Waste of money. The taste is ok, but they don’t get the job done. I bought them because I have dry mouth from radiation therapy and there was no improvement. Next!

tart and delicious!
Flavor Name: Tart Cherry, Size: 3.85 Ounce (Pack of 1)
These are (to me) very flavorful and just thinking about them makes my mouth water! I love that these don’t promote dental decay and that they help keep my mouth from getting dry. I also love that they only contain natural ingredients that actually help your dental health as opposed to artificial sweeteners that are very unhealthy. I will definitely purchase these in the future and I am recommending them to my family and friends!

These are a little sour, but I enjoy the flavor. Individually packaged and reasonably priced.
