Alternative Names
SialolithiasisCauses
During eating, saliva (spit) is produced by the salivary glands in the mouth. The chemicals in saliva can crystallize into a stone that can block the salivary ducts. When saliva cannot exit a blocked duct, it backs up into the gland, causing pain and swelling of the gland. The submandibular glands, at the back of the mouth on both sides of the jaw, are most often affected by stones.
