It's a result of gum hardening and teeth formation . Try giving a teether, washed cloth, a frozen feeder or a safe toy to chew on.

Hi

Baby is not putting teethers in his mouth.

This is basically due to more saliva formation in the mouth. This is also a stage where of child development where there could be the gums hardening for which the child wants to put everything in the mouth. U can use a teether and sterilize it when not in use
