What Causes Excess Salivation?

Monday, 17 September 2012 09:51 AM

Question: I have an odd problem, excess salivation. I constantly have to swallow. What could be the cause?

Dr. Hibberd's answer:
Excessive saliva — increased amounts of saliva in your mouth — is usually a temporary problem and rarely cause for concern. Normally, your salivary glands produce up to 1 to 3 pints (0.5 to 1.5 liters) of saliva a day. However, because swallowing occurs frequently and unconsciously, you don't generally notice the saliva. If you suddenly seem to have excessive saliva in your mouth, it could be because your salivary glands are making more saliva than usual or because you are having difficulty swallowing. Common causes include dentures that are new or do not fit well, stomatitis, or an inflammation of mucous membranes in your mouth, gastroesophageal reflux disease (GERD), infection in your mouth or throat, taking certain medications such as clonazepam (Klonopin), clozapine (Clozaril, Fazaclo ODT), pilocarpine (Salagen) and carbidopa-levodopa (Parcopa, Sinemet). Causes that could lead to a decreased ability to swallow or to retain saliva in your mouth include sinusitis, allergies, enlarged adenoids, or tumors that affect your tongue or lip movement, certain neurological and muscular disorders. You need to work with your doctor to determine the exact cause in your case.
