same problem with me, i brush my teeth twice a day. but when i wake up i cant have a lie in due to the fact that every 2 mins my mouth gets full of bad saliva, sometimes brown mostly ordinary saliva. i have to spit every 2 mins or so otherwise my mouth gets full. therefore i can never have a lie in, whenever i wake up - thats it i have to get up. so annoyin, been happening for about a year now.
No during the day time I am fine . I do wear denture with made from the old mercury mixture . This doesn't happens at all time during the night. For example I notice when I eat 3-5hrs before bed time I do fine and sleep like a baby. When I eat minute before bed time then I wake up one during the middle of the night .
Hi hricks36, how are you doing? Since when you have noticed this excessive salivation during sleep and do the same happen in daytime? Have you consulted your family doctor or a dental surgeon and have received any kind of treatment. Common causes are bad oral hygiene, inflammation of oral mucosa, respiratory tract infection, sinus infection, sleep apnea etc. Here are links to know more on the symptoms and treatment aspect, which you might be interested in:
