Saliva drains into the mouth from these glands down short ducts (tubes). The parotid glands lie just below and in front of the ears. Saliva passes down the parotid duct into the inside of the cheeks. The submandibular glands are under the floor of the mouth - one on each side - and drain saliva up into the floor of the mouth. The sublingual glands are just beneath the tongue. A salivary gland stone is sometimes called a sialolith or a salivary calculus. Most salivary stones are mainly made of calcium. However, there is no abnormality of the blood calcium level or any other problem with calcium in the body. Salivary gland stones are not usually associated with any other disease.The size of the stone can vary from less than 1 mm to a few centimeters in diameter. About 9 in 10 stones are less than 10 mm in size. About 8 in 10 salivary stones form in one of the submandibular glands.
