If it is transient, a salty taste in the mouth may indicate dehydration, medication side effects or post-nasal drainage. If the salty taste is ongoing or persistent, it may indicate a more serious issue worthy of medical investigation.

Because fluids become more concentrated when an individual is dehydrated, mild flavors already present in the saliva become stronger and more noticeable. Rehydration and dietary changes can help alleviate and prevent a salty taste in the mouth. The potential side effects of certain medications, such as chemotherapy or thyroid drugs, include a salty taste in the mouth. Sinus infections, salivary glands diseases and bacterial infections cans also cause a salty taste in the mouth.
