Salivary glands make saliva and secrete it into your mouth through openings called ducts. Your mouth contains three major types of salivary glands:
Hundreds of other minor salivary glands exist in your mouth and throughout your digestive tract. These glands are so tiny you can't see them without a microscope. You can find them in places like the lining of your lips, inside your cheeks, and more.
Your salivary glands continually create saliva to keep your mouth and digestive tract moist. When something touches your mouth or tongue or begins to chew saliva's secretion increases. While eating, saliva helps lubricate the food so it can pass through your esophagus to your stomach more easily. It also contains certain enzymes that help in the early stages of digestion, so it can soften and break down the more complex products your body needs to store as energy.
Your saliva — and salivary glands — also play an essential role in oral health. It's filled with minerals that help lower the acid level in your mouth, a process that keeps your tooth enamel from wearing and cavities from forming. Plus, saliva helps wash away the food debris that leads to the acid-forming, enamel-wearing bacteria.
A lack of saliva causes a condition called xerostomia, or dry mouth, which can cause an increase in tooth decay, bad breath, and even digestive problems. Because these glands secrete saliva through a tiny opening at the end of a tube, they sometimes get blocked or inflamed, causing less saliva flow.

Specific medications can also lower saliva production and cause dry mouth. Fortunately, your dentist can prescribe a product to help relieve those symptoms or work to find an alternative that can reduce dry mouth effects.
With your salivary glands working around the clock to help keep your digestion on track and your enamel intact, you need to make sure those glands are happy and healthy. Follow these tips for helping your salivary glands function properly, and talk to your dentist if you experience any pain or dry-mouth symptoms.
