"A salivary gland inflammation needs to be considered for watering as irritable gland do secrete excess saliva. Your primary care physician can examine or palpate all three major salivary gland; namely parotid, submandibular and submental. Herbs too can be responsible for the irritation of the salivary gland resulting in increased production of the saliva (if you are using any). But many times it subsides spontaneously and no cause is found. Consideration of the gastroesophageal reflux disease (GERD) should also be done for excess water in mouth. Sleep disorders, anxiety and emotional disorders also are considered for cause of excess water in mouth. Read about the GERD symptoms." -Dr. Arun Phophalia Just Answer(dot)com
