#asktheexpert Hi doctor good morning! my son is 5 months old. He has been drooling so much for a month. Is it an early sign of teething?

A. This becomes especially apparent at 3 to 6 months of age. The increased flow of saliva that often signals the appearance of a new tooth seems to soothe tender gums; however, if your baby appears to be drooling excessively and looks ill, she may be having trouble swallowing, which requires medical attention
