What Is Xerostomia?
1. Saliva
Saliva is the watery fluid that is found in our mouths. It might be something that can just, quite literally, be spat out, but that does not mean that it has no value to us. Indeed, it actually performs some very important functions for us. One of these is that it helps to soften our food in the process of mastication.
Saliva also helps to limit the build up of bacteria in the mouth because it is slightly antiseptic, while it also helps to wash away food particles that might encourage a buildup of bacteria. It even enhances our sense of taste, making our food to taste so much better.
