Thank you for the query.
Usually upper front teeth which are termed as central incisors erupt at the age of 6 to 8yrs . It varies from person to person.
But, when you got the milk teeth removed did you find any erupting teeth from inner side of the milk teeth .And i would like to know why did you get it extracted ? where they mobile? or infected?
I would suggest you to see your dentist
for clinical examination to know whether the permanent teeth
is erupting or not .If not get an x-ray done of the area to rule the presence of the teeth in the jaw .
Hope this information helps you.
