I would not recommend this.
Size: 0.75 Ounce (Pack of 2)
For me it only helped for about 15 minutes at the most. I do NOT want to have to keep spraying all day!

Helps with dry mouth
Scent Name: Berry, Size: 40 Count (Pack of 1)
I purchased this because I’ve noticed as I get older that my mouth produces less saliva. I have been experiencing dry mouth more and more often, especially at night. I started mouth taping and using xylitol melts and I’ve seen a huge improvement in my overall oral health. They are easy to use, taste good and were comfortable overnight. Highly recommend.

Instant Results
Scent Name: Berry, Size: 40 Count (Pack of 1)
I’ve been struggling with dry mouth for some time due to Sjorgens disease.
After trying various remedies with little success, I stumbled upon these Xylitol tabs, and I can’t believe how fast they worked.
From the first use, I noticed a significant difference. The tabs dissolve quickly and have a pleasant, refreshing flavor that instantly alleviates that uncomfortable dry feeling. Not only do they help stimulate saliva production, but they also keep my mouth feeling moist for a longer rime.
If you’re dealing with dry mouth, I highly recommend giving these Xylitol tabs a try. They're a game-changer!

Works well!
Scent Name: Berry, Size: 40 Count (Pack of 1)
Nice flavor. They don’t melt real fast like the ACT I’ve been using. They are smaller than I thought and I didn’t think they would last as long as they do. Keeping my mouth/throat moist as they said. I like the way they stick to your mouth and you don’t have to worry about swolling accidentally!
