Question
A four-month-old baby is experiencing drooling, and it has been going on for some time. Parents are confused about whether medication is needed and hope to receive professional medical advice.
Answer
Drooling in infants can be caused by two reasons: first, physiological drooling is a common occurrence. As infants grow, their salivary glands gradually mature, leading to an increase in saliva production. However, the control function of saliva is not yet fully developed, resulting in drooling. Second, pathological drooling may be related to oral diseases such as oral ulcers, herpes, pharyngitis, or stomatitis. If parents are concerned, it is recommended to consult a pediatrician to determine whether further medical intervention is necessary.
