Diagnosis

To determine the cause of your dry mouth, your doctor likely will review your medical history and all medications you're taking, including over-the-counter medications, and examine your mouth.

Sometimes you may need blood tests, imaging scans of your salivary glands or tests that measure how much saliva you produce to identify the cause of your dry mouth. If your doctor suspects your dry mouth is caused by Sjogren's syndrome, a small sample of cells (biopsy) taken from salivary glands in your lip may be sent for testing.
