Dr Vandan H KumarFather of a 7 yr 4 m old boy1 Year agoA. for tooth development and eruption the first important thing is that the child should not have deficiency of calcium and vitamin d.
first tooth eruption can occur anytime between 6 months to 18 months of age.
deficiency is there or not will be told by the doctor.
there is no need to worry because many times the first tooth eruption may occur as late as 16 to 18 months of age also.
so if your personal doctor is not worried then no need to worry from your side
they are fontanelle and usually they will close by maximum 18 months of age and only sometimes by 2 years of age.
they are normally present in all infants and is important for the development growth of the brain
it is important to see that the child is not suffering from calcium and vitamin d deficiency as well as the child is not having any other complaindts because their deficiency is the common cause of delayed closure of fontanelle.
