This makes it easier for me to swallow, which consequently helps my TMJ. I use the gel version at night (this spray doesn’t last all night, but the gel does). I keep one by my computer, reading chair, desk, and in the car. I use it several times a day, so 4 bottles last about a month. Recommended by my dentist, who says most of her patients like it.Forty years ago, this kind of product was unflavored and termed “artificial saliva.” That was so unappealing, I couldn’t get myself to use it. The flavor and term of this product (“dry mouth spray”) really improve its appeal. I wish four bottles lasted longer, but it’s tremendously helpful.
