Your body’s work includes producing 2 to 4 pints of saliva daily. The six glands primarily responsible for this task are located inside each cheek, deep underneath your tongue, and near your front teeth by the jaw bone.
After the saliva is produced it moves through tubes called salivary ducts. You can test drive the process by yawning. Chances are you’ll end up with a small pool of saliva under your tongue because when you yawn your facial muscles push against your sublingual salivary glands, which produces a small stream of salvia.
Yawning is a quick fix for a temporary dry mouth. But if you don’t produce enough salvia on a regular basis, you have “xerostomia”– more commonly known as dry mouth.
