The salivary glands consist of the submandibular gland, the sublingual gland and the parotid gland. They produce liquid and enzymes that help with digestion, that helps control infection and that aids in mechanical cleaning of the mouth and teeth. The glands secrete these substances into the mouth. Infections of the salivary glands can occur from viruses, such as mumps, and bacterial infections. Bacterial infections tend to occur, if the salivary glands or ducts become obstructed, or if there is poor dental hygiene.
Causes of Salivary Gland Infection
Viruses, particularly mumps, involves the salivary glands. Bacterial infections are often the result of obstruction of the gland. This diminished flow can lead to bacteria entering the gland from openings of the ducts in the mouth. Salivary duct stones, strictures or tumors can lead to obstruction of the glands.
Signs and Symptoms of Salivary Gland Infection
Infections that involve the salivary glands produce pain and swelling of the glands. Depending on which gland is involved, this can lead to pain and swelling of parotid gland (behind ear) or sublingual gland (under the tongue) or submandibular gland (under the chin). There may be a decrease in the flow of saliva. Peculiar tastes in the mouth may occur. Pus may drain out of the ducts as they enter the mouth. producing a bitter taste. Swollen lymph nodes will produce painful lumps in the neck. Fever and chills may occur.
