Introduction
In adults, drooling is mainly divided into normal physiological phenomena. The primary cause is overactivity of the vagus nerve during sleep, leading to a series of physiological changes. Under normal conditions, saliva secretion amounts to approximately 1500 ml per day, with a slight increase during sleep. Abnormal conditions include oral diseases such as oral mucosal lesions accompanied by erosion or oral ulcers.
Drooling is a common occurrence in daily life. It is most frequently seen in infants and children, but some adults also experience drooling. So, what causes drooling in adults?
What Causes Drooling in Adults?
Drooling in adults can be divided into normal physiological phenomena and abnormal conditions. Under normal circumstances, during sleep the vagus nerve becomes overactive, leading to a series of physiological changes. Normally, saliva secretion is about 1500 ml per day, and this amount slightly increases during sleep. In abnormal cases, oral diseases such as oral mucosal lesions with erosion or oral ulcers can significantly increase saliva production due to pain stimulation. Oral foreign bodies, such as ill-fitting dental restorations, or even oral tumors, may also lead to increased salivation. Oral inflammations like severe periodontitis or pericoronitis of wisdom teeth, especially when periodontal abscesses are present, can stimulate inflammation and result in excessive saliva.
Drooling in adults can be classified as either physiological or pathological. Physiological drooling usually does not require treatment, whereas pathological drooling may be associated with oral diseases. From the perspective of Traditional Chinese Medicine (TCM), spleen deficiency can also be a contributing factor. Because the underlying causes vary, treatment methods differ accordingly. Physiological drooling—caused by factors such as misaligned teeth or dreaming about eating—typically does not need medical intervention. Pathological drooling has various causes, including gingivitis and periodontitis. Maintaining good oral hygiene, avoiding heat-inducing foods, and eating light, mild foods are recommended.
In general, drooling does not cause serious harm to the body. However, individuals experiencing pathological drooling should seek timely medical evaluation and treatment at a hospital. We hope this information helps you. Wishing you good health and a happy life.
