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.
Erupting permanent teeth cause the roots of baby teeth to be reabsorbed so that by the time they are loose there is little holding them in place besides a small amount of tissue. Most children lose their baby teeth in this order: Baby teeth ordinarily are shed first at about age 6 when the incisors, the middle teeth in front, become loose. Molars, in the back, are usually shed between ages 10 and 12, and are replaced with permanent teeth by about age 13. Children usually wiggle their teeth loose with their tongues or fingers, eager to hide them under their pillow for the tooth fairy.. If your child wants you to pull out the already loose tooth, grasp it firmly with a piece of tissue or gauze and remove it with a quick twist.
