 Overview—Tooth
Development
Teeth vary in size, shape and their location
in the jaws. 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 primary
(baby) teeth, which often erupt about six months of age. They are then shed
at various times throughout childhood.
By age 21, all 32 of the permanent teeth
have usually erupted.
