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.
After a two-year break (about age 10), the next four baby teeth to be lost are the lower canines and upper first molars. These are typically followed around age 11 by the lower first molars. The lower second molars tend to be lost about the same time as the upper canines and second molars.here are normally 20 baby teeth by the time a child reaches age 3. These primary teeth then remain unchanged for about three years. Not much happens to the baby teeth between 3 and 6 years of age.
