Even if you haven’t had any water to drink for a little while, your mouth always seems to still have some water in it! You’re probably used to referring to that water as saliva, or maybe “spit.” Saliva is the wet and slimy liquid that helps to keep your mouth moist. It’s made up of mostly water and a few other natural chemicals found inside your body.
Saliva has a few main jobs, such as helping you to talk more easily and making it easier for you to chew and taste your food! Saliva also helps you to start breaking down your food before your food even reaches your stomach!
