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.

Very Helpful with dry mouth due to Autoimmune illnesses
Size: 1 Ounce (Pack of 1)
I have an illness that causes very dry mouth and nothing seems to work even a $65.00 prescription that was recommended. My hygienist suggested I try Salivea, so I got the spray. I can honestly say nothing has work quite like this. It's only been a few days but I also bought the toothpaste and mouthwash. I'm highly impressed so thank you Loretta for recommending
