Salivary glands are small organs in the mouth that produce saliva, a fluid that helps with digestion and keeps the mouth moist. There are three main types of salivary glands: the parotid glands, located near the ears; the submandibular glands, found under the jaw; and the sublingual glands, located under the tongue. Saliva contains enzymes that begin breaking down food and helps wash away bacteria, keeping the mouth healthy. When we eat, the sight, smell, or taste of food triggers these glands to produce more saliva. This process is essential for chewing and swallowing, making it easier to enjoy our meals. Additionally, saliva plays a role in protecting teeth from decay and aiding in the overall health of the oral cavity.
