Besides these glands, there are many tiny glands called minor salivary glands located in your lips, inner cheek area (buccal mucosa), and extensively in other linings of your mouth and throat. Salivary glands produce the saliva used to moisten your mouth, initiate digestion, and help protect your teeth from decay.
The glands that make saliva are called salivary glands. The salivary glands sit inside each cheek, at the bottom of your mouth, and near your front teeth by the jaw bone. There are six major salivary glands and hundreds of minor ones. Saliva moves through tubes called salivary ducts. Normally, the body makes up to 2 to 4 pints of saliva a day. Usually, the body makes the most saliva in the late afternoon.
