Healthy salivary glands are essential for producing saliva, which supports swallowing, digestion, and protects teeth and gums from infections. There are three main glands—sublingual, submandibular, and parotid—along with hundreds of minor glands and ducts, creating a complex system crucial for oral health. When this system is compromised, unpleasant symptoms may arise, including swelling, redness, dry or painful mouth, a foul taste, pus discharge, and discomfort while eating. In some cases, patients may also experience fever.
While salivary gland cancer is rare, benign growths, infections, cysts, and salivary stones are relatively common and require prompt treatment to restore healthy function.
