Why do baby teeth fall out?

Short answer

As the jaw and permanent teeth develop, the roots of baby teeth are gradually absorbed so the permanent teeth can take their place.

How it works

Timing and order vary between children. Strong pain or injury should be checked by a dentist.

Key point

The practical point is this: Strong pain or injury should be checked by a dentist.
