What Could Cause Salty Saliva on One Side of the Mouth?

Salty saliva on one side of your mouth might be due to a change in how your salivary glands work, which could be influenced by an infection, medication, or other local factors.

Explanation

Sometimes you might notice that the saliva on one side of your mouth tastes saltier than usual. This can happen when one of your salivary glands produces saliva with a higher salt concentration. Changes in the function of the salivary glands can be caused by local infections, inflammation, or even the effects of certain medications that alter how saliva is made. For example, even conditions like a viral infection might change the way your body makes saliva, as seen in some cases with COVID-19, where patients experienced changes in taste and saliva consistency. In addition, the balance of fluids and electrolytes in your saliva can be influenced by metabolic hormones and local factors, meaning that one side may be affected differently than the other. If you notice that the salty taste persists or if it is accompanied by other symptoms like pain or swelling, it’s a good idea to talk with a healthcare provider. They can help figure out if there is an underlying issue with your salivary glands or if a change in medication or other treatment might help.
