Patient's question:
NoDoctor's answer:
Hello, after the age of one, with the proper development of the brain, drooling usually occurs less frequently. By the time the child is 2-3 years old, swallowing function and the central nervous system are further developed, and drooling no longer occurs. It may be pathological drooling rather than physiological. This could be caused by developmental issues in the nervous or endocrine systems, inflammation in the mouth, or indigestion, among other reasons. It is necessary to seek medical diagnosis and treatment.
