Dr Vandan H KumarFather of a 7 yr 4 m old boy3 years agoA. the noise as well as the crackling sound your hearing is due to the the bones.
there is space between the bones and when they move you will hear them.
it will usually decrease with increasing age of the child and it is totally normal and it is not a fracture.
still if the child is having pain then only you have to meet the doctor
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 least two times per day
also the increased salivation is due to the pre tooth eruption pain and the irritation of dirty things the child places in the oral cavity
