Hello there .
I can undertand your concern .
Its perfectly normal to sleep with an open mouth .
Infact , many people sleep with open mouth .
Its not harmful to sleep with an open mouth , apart from the odd chances of bugs getting inside .there is no medicine as such to make a person close the mouth while sleeping . You just have to train yourself .
Best regards,
Dr. Anil Kumar Jain.
