What causes excessive saliva production in the mouth?

Excessive saliva production in the mouth may involve several factors. 1. Dietary factors are a significant cause; consuming overly acidic, sweet, or spicy foods can stimulate the salivary glands to produce large amounts of saliva. 2. Poor oral hygiene may also lead to increased saliva secretion, as excessive bacterial growth in the mouth can stimulate the salivary glands. 3. Emotional factors can affect saliva production as well; negative emotions such as stress and anxiety may excite the sympathetic nervous system, thereby affecting nerve conduction and leading to increased saliva secretion. 4. Certain medical conditions may also cause abnormal saliva production. For example, oral diseases such as periodontitis and mumps, as well as digestive system disorders like bile reflux gastritis and reflux esophagitis, can all result in increased salivation. If experiencing such symptoms, it is recommended to seek timely medical attention and receive targeted treatment after identifying the underlying cause.
