About Teeth

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. The first tooth usually erupts at 4 to 6 months of age. However, every child is different and some do not see a first tooth until 1 years of age. By 2 ½ years old, most children will have 20 primary (baby) teeth. Children usually lose their first tooth around the age of 5. They are often shed at various times throughout childhood. Around age 6, you will see the permanent 6 year molars erupt in the back of the mouth. Approximately around age 12, most permanent teeth have erupted. By age 21, all 32 of the permanent teeth, including wisdom teeth, have usually erupted. However, some children are born without wisdom teeth.
