These work for dry mouth!!
Flavor Name: Cinnamon, Size: 230 Count (Pack of 1)
Severe dry mouth from Chemo treatments. These were recommended. They work great overnight while sleeping. Stick one to the roof of your mouth and it helps. Not as good new but you don’t wake up with your tongue glued to the roof of your mouth. These are worth trying.

Not for me
Flavor Name: Cinnamon, Size: 230 Count (Pack of 1)
I was excited to try these as cinnamon is a favorite of mine. I've used the fruit flavored and liked them, but these were problematic for me. First they badly stained my night guard (which I've tried numerous things but can't remove the orange color) and second they caused some mild injury to the mucus membranes of my mouth. I've pitched them and reordered the fruit flavored.
