Not everyone loses their baby teeth!
Losing baby teeth is a rite of passage, not to mention a small source of income for most kids. By age 3, the average child has a full set of 20 temporary teeth. These little chiclets loosen and eventually fall out as the permanent teeth below start to erupt. Children typically start losing teeth around 5 or 6 and finish in their early teens. But if a person doesn't have a replacement permanent tooth, that baby tooth will stay put.
