The sublingual gland is one of the three major salivary glands in the human body, located beneath the tongue. It is responsible for producing saliva, which aids in digestion and helps keep the mouth moist. The saliva from the sublingual gland contains enzymes that begin the breakdown of food and also helps in swallowing. This gland is smaller than the other major salivary glands, the parotid gland and the submandibular gland. It primarily secretes a type of saliva that is mucous in nature, which contributes to the lubrication of food. Proper functioning of the sublingual gland is essential for oral health and digestion.
