Drooling while sleeping is usually caused by malocclusion, pharyngitis, periodontitis, lying on the side or sleeping with the mouth open, etc. In serious cases, it is recommended to go to the hospital for a clear diagnosis.
1. Malocclusion: due to abnormal development of teeth and daily bad habits such as biting things, can lead to malformation of the teeth arrangement, which in turn affects the surrounding muscle contraction, resulting in the mouth can not be completely closed during sleep and drooling performance.
2. Pharyngitis: bad dietary habits or air pollution and other influences, can lead to bacteria into the throat, the mucous membrane of the throat to produce stimulation and cause congestion, edema and other inflammatory reactions, which will stimulate the secretion of saliva, resulting in a large number of drooling symptoms during sleep.
3. Periodontitis: unclean teeth will lead to teeth and gums infected by bacteria and prone to inflammation, which will stimulate the secretion of saliva and the appearance of drooling during sleep.
4. Sleeping on the side or sleeping with the mouth open: the habit of sleeping on the side will make the secretion of saliva out of the mouth, thus causing the performance of drooling in bed. Sleeping with the mouth open or when a child is teething will also stimulate the gums and oral mucosa, making the performance of sleep drooling.
In order to improve the symptoms of drooling while sleeping, it is recommended to go to the hospital for treatment of severe cases.
