Salivary glands produce saliva, which is critically important for oral health and the digestive process. A healthy adult is estimated to secrete an average of 1000 to 1500 ml of saliva daily. Saliva performs essential functions such as cleaning the oral cavity, maintaining pH balance, moistening food, and facilitating swallowing. With numerous roles ranging from preventing bad breath to initiating the first stages of digestion, saliva is indispensable for overall health.
