I love Dr Jen products
Item Package Quantity: 1, Item Package Quantity: 1
This is my favorite dry mouth gel that I’ve tried. I sleep with my mouth open and take medication at night that causes dry mouth so I have zero saliva during sleep. This gel has helped the most. Sometimes I wake up in middle of night and my mouth will still be dry so I reapply. The taste is very mild , I love that it has nano hydroxyapatite as I have gerd and like the extra enamel support.

Save your money......
Size: 1 Ounce (Pack of 1)
I had high hopes for this, but sadly, it fell short. I have to wear a CPAP mask at night & the dry mouth is just one of the things I hate about it. I saw this, read the reviews & decided to give it a try. I used it per the directions, but it really did nothing to alleviate the dry mouth. I'm giving it 2 stars because it doesn't taste bad, but that's the only good thing I can say about this.
