Hello doctor! My baby boy is 3 month 7 days old. He has excessive salivation and drooling over mouth. What may be the reason?

A. to decrease this you have to maintain hygiene of the oral cavity by regular cleaning the oral cavity with the help of your finger as a less you can use clean cotton cloth. this has to be done at lexast two times per day also the increased salivation is due to the pre tooth eruptixon pain and the irritation of dirty things the child places in the oral cavity
