Smile Development

The developing smile

Teeth vary in size, shape and location in the jaws. These differences enable teeth to work together to help you chew, speak and smile. Teeth also help give the face its shape and form.

When a baby is born, the 20 primary teeth are already present in the baby’s jaws. The teeth often begin erupting as early as six months of age. They are shed at various times throughout childhood to make room for the permanent (adult) teeth. By age 21, all 31 of the permanent teeth have usually erupted.

Keep in mind that there are differences in times when children’s teeth erupt and are shed. These charts will help you identify primary and permanent teeth and understand how the mouth develops during childhood and teen years.
