A primary tooth falls out because it is being pushed out of the way by the permanent tooth that is behind it. Slowly, the permanent teeth grow in and take the place of the primary teeth. By about age 12 or 13, most kids have lost all of their baby teeth and have a full set of permanent teeth. There are 32 permanent teeth in all â 12 more than the original set of baby teeth. Most people have four teeth (called wisdom teeth) grow in at the back of the mouth when they're between 17 and 25 years old.
By 12 months babies usually have 4 to 8 teeth. By 18 months 12 teeth and by 3 years all 20 baby teeth will generally be in place. Baby teeth will be lost between the ages of 6 and 12 years to make way for permanent teeth (also called adult teeth). Teeth generally appear in a certain order.
