👉 Sip fluid, also known as sip fluid or saliva, is a clear, watery substance produced by the salivary glands during speech. It plays a crucial role in lubricating the oral cavity, facilitating smooth and efficient articulation of sounds by reducing friction between the tongue, teeth, and the roof of the mouth. This fluid also helps in cooling the mouth and enhancing taste perception by dissolving taste molecules. Additionally, sip fluid contains enzymes like amylase that begin the digestion of carbohydrates and electrolytes that help maintain oral pH balance, contributing to overall oral health.
