Drooling in bed is a relatively common problem that often requires no special treatment. The main treatment for drooling in bed is by changing the sleeping position. Problems with sleeping posture may cause drooling in bed at night. You can try to control it by changing your sleeping posture to sleeping on your back, which will control the flow of saliva, but you need to pay attention to whether you feel breathing difficulties and acid reflux while sleeping. Although drooling in sleep does not require special treatment, it is worth noting that some children or adults have open mouth breathing, and some have the bad habit of mouth breathing not only during sleep but also on weekdays. Mouth breathing can lead to dry mouth, enlarged tonsils and adenoids, and can also affect the development of children’s facial bones and teeth, affecting aesthetics in the future. Therefore, when mouth breathing is found, parents should take their children to the ENT department for examination and treatment of enlarged turbinates, deviated nasal septum, rhinitis and other problems, so as to remove the cause of mouth breathing. In conclusion, drooling in bed does not require special treatment, but one should be alert to other problems that it may indicate.
