What Causes the Corner of the Mouth to Feel Like It's Drooling?

Sometimes, you might feel as if saliva is coming out of the corner of your mouth more than usual. This can happen when your body makes more saliva than normal or when the muscles around your mouth do not close tightly enough to keep the saliva inside. For instance, in burning mouth syndrome, you might experience pain, burning, and extra saliva along with a feeling of drooling. In other cases, conditions that affect your nerves and muscles—like Parkinson’s disease—can make it harder for you to control saliva, leading to drooling. Certain medications or even other salivary secretory problems may also play a role. These issues change how your body produces and manages saliva. If you are often bothered by this sensation or notice other symptoms, it’s a good idea to speak with a healthcare provider. They can look into your symptoms and help find ways to manage or treat the problem.
