Saliva is needed for the proper functioning of the tongue. A dry tongue can't taste a thing so saliva helps the tongue and our sense of taste by keeping it wet. Saliva moistens food and helps to break it down, which in turn makes it easier for the tongue to push the food to the back of the mouth for swallowing.
The tongue is not just important to your oral health â it's also considered an integral part of the body's digestive system â it's responsible for moving food to your teeth, and when chewed food is ready to be swallowed, the tongue moves it to the back of the throat so it can proceed into the esophagus.
