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.
At age six or seven, the first adult (or permanent) teeth come in. They are known as the first molars, or the six-year molars.. They come in at the back of the mouth, behind the last baby (or primary) teeth. They do not replace any primary teeth. Also at around age six, children start to lose their primary teeth.The roots slowly get weak, and the tooth falls out. Children lose primary teeth until they are about 12 years old. It's okay for children to wiggle their primary teeth if they are loose.lso at around age six, children start to lose their primary teeth. The roots slowly get weak, and the tooth falls out.
