Other causes include infection in the mucosa of the mouth or a post-nasal drip due to chronic sinusitis. If you have an increased production of tears this could be a very rare cause. An even rarer cause is due to brain lesions such as a new epileptic lesion, brain tumor or a migraine. If you are not dehydrated and do not have sinusitis then you should seek an appointment with your physician.
