Answer:
When you begin chewing, glands in your mouth and throat begin to secrete saliva. This process can start with the sight or smell of food. The liquid aids digestion, moistens your mouth, reduces infections in the mouth and throat, and helps protect your teeth and gums. You have 3 major pairs of salivary glands:
Parotid glands, the largest, are on both sides of your face, in front of your ears
Submandibular glands are underneath your jawbone
Sublingual glands are underneath your tongue
Your upper digestive tract and your esophagus also contain smaller clusters of salivary glands. Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.
A condition known as dry mouth (xerostomia) occurs when you don’t have enough saliva in your mouth. This can make it difficult for you to chew and swallow food. Stress or dehydration can cause occasional xerostomia. Certain medicines or more serious conditions such as diabetes and Sjogren syndrome can also cause it. To reduce the symptoms of dry mouth, drink plenty of water, take sips of water while eating, and don't have caffeinated or alcoholic beverages. These can make dry mouth worse.
