👉 Diet fluid, often referred to as oral fluids, is the liquid that exists in the mouth and throat, including saliva. Saliva, a primary component of diet fluid, plays a crucial role in oral health by lubricating food for easier chewing and swallowing, initiating the digestion process through enzymes like amylase, and maintaining a balanced oral pH. It also helps in the remineralization of tooth enamel by providing calcium and phosphate ions, thus preventing tooth decay. Additionally, diet fluid aids in the mechanical cleansing of the mouth, removing food particles and debris, and contributes to the overall comfort and health of the oral cavity.
