Sialadenitis, or salivary gland inflammation…
…is an often painful bacterial infection of a salivary gland. The condition, which most commonly affects the parotid gland, may result when the duct into the mouth is blocked. Sialadenitis creates a painful lump in the gland, and foul-tasting pus drains into the mouth.
Sialadenitis most commonly affects older adults with salivary stones, but can also occur in babies during the first few weeks after birth. Those who have xerostomia (chronic dry mouth), or suffer from anorexia, may also be prone to the condition.
Swelling, pain, fever, and chills are frequently reported symptoms of the disease. If left untreated, salivary gland infections can cause extreme pain, increased fever, and pus collection.
