What Causes Salivary Stones? Infected Salivary Gland Causes. In our bodies, we have several glands that are responsible for the production of saliva in our mouths. Saliva helps us chew, eat, swallow, and even speak. When sialolithiasis or mouth gland infections occur, our saliva production can become limited causing negative effects to take place. Though our saliva is made up of almost entirely water, sometimes other minerals and chemicals make their way into our saliva ducts, which is what causes calcified growth in the mouth.
