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.
Actually, amount of teeth in a child depends on their age. Baby teeth start to fall out at about age 6 and are gradually replaced by secondary teeth until nearly age 12. A new teeth also come in throughout this time. By puberty, almost all children have 28 teeth. In all, children have 20 baby teeth â 10 on the top and 10 on the bottom. These teeth function as placeholders for the adult teeth that grow in following the baby teeth fall out.
