When do children usually start to have their teeth falling out?

6 years: Normally the 2 lower front teeth loosen first at the age of 6 years.

5 1/2 years: The lower front teeth are the first teeth to loosen and wiggle. This can happen around age 5 1/2 though some children can start much later. It is more important on the sequence of which teeth exfoliate( fall out) that the timing or age. Every child has their own time table.
