The parotid glands are the largest salivary glands located near the jaw, just in front of the ears. They produce saliva, which helps in digestion and keeps the mouth moist. Each person has two parotid glands, one on each side of the face. These glands are responsible for secreting a watery fluid that contains enzymes, particularly amylase, which begins the process of breaking down carbohydrates. The saliva produced by the parotid glands also plays a crucial role in oral health by helping to wash away food particles and bacteria, reducing the risk of tooth decay and gum disease.
