<s>[INST] I started producing alot more sliva about 3 months ago. I dont know WHY it started? I have never had this problem before. It is worse during the time I try to fall asleep. I t seems to be worse when I crunch my left / lower teeth together also. The problem has gotten worse over the past week! [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. According to symptoms mention in the query the excess saliva production occur due to a condition called BRUISE means clenching of teeth specially while sleeping. There can be many reasons for bruise, but the most common reasons are stress, anxiety and temporomandibular problems (TMJ)You should consult dentist for proper examination. Doctor will take history and may order X-ray or CT scan to find out the exact cause. If the problem is due to stress and anxiety the doctor will give your mouth guard and may prescribe muscle relaxant (orthodox MR) and medicine like scopolamine for reducing the quantity of saliva. Doctor also ask you to reduce your stress. If the problem is related to TMJ the doctor will refer you to oral surgeon for proper treatment. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
