There are three pairs of major salivary glands in the mouth and throat: submandibular, sublingual, and parotid, along with several hundred smaller minor salivary glands. Saliva drains into the mouth through small tubes called ducts. One of the common causes of swollen salivary glands are salivary stones. Salivary stones are buildups of crystallized saliva deposits. Sometimes salivary stones can block the flow of saliva. When saliva can’t exit through the ducts, it backs up into the gland, causing pain and swelling. Pain is usually off and on, and typically worsens when you eat. This blockage is often associated with infection. Removal of the stones is the most common way to resolve your symptoms. Dr. Schleiffarth is an expert in the management of salivary gland problems. Watch this video on Sialoendoscopy, a minimally invasive technique to remove stones from the salivary glands.
