Eruption Charts:
These differences enable teeth to work together to help you chew, speak and smile.
They also help give your face its shape and form. At birth people usually have 20 baby (primary) teeth, which start to come in (erupt) at about 6 months of age.
They fall out (shed) at various times throughout childhood. By age 21, all 32 of the permanent teeth have usually erupted.
