My child has a permanent tooth coming in behind their baby tooth

If it is on the bottom front, it is very common, and most likely will correct itself. We usually wait a few months before talking about doing any treatment as far as taking that tooth out, the tongue will push the permanent tooth into the correct spot once the baby tooth falls out. If this happens on the top, it most likely will not correct itself, so the parent should call for an appointment to take a look.
