Dry Eyes and Mouth

Okay.

When a person has dry mouth and swelling on one side, an obstructed salivary gland is a real possibility. The most common cause of obstruction is a stone (much like a kidney stone or gallstone), but there are other possibilities. An infection -- usually bacterial -- can also cause swelling on one side, and bacteria can complicate an obstruction.

Swelling in one parotid gland is a reason to see your doctor sooner than later. Understanding the cause is critical so that you can get prompt, appropriate treatment.
