Why does my child have two teeth in one place, like a shark?

A normal pattern of tooth eruption is when a permanent tooth absorbs the root of a primary (baby) tooth. This causes the baby tooth to have less anchorage in the bone and loosen and eventually fall out. Sometimes, the permanent teeth erupt behind the baby teeth and do not cause the natural phenomenon of loose teeth. In this case, Dr. Kimmy can “wiggle” the baby teeth so that the tongue can push the permanent teeth into place.
