Why do we lose baby teeth?

Quick Answer

Baby teeth fall out because your jaw grows and your adult teeth are getting ready. The new teeth push up underneath, making baby teeth wiggle until they’re loose enough to come out—then a stronger adult tooth takes its place.

Story Synopsis

A wiggly tooth can feel exciting
 and a little strange. This story gently walks children through what’s happening when baby teeth start to move. It begins by reminding them that when they were very small, they grew a first set of teeth made just for a small mouth. As kids grow, their jaw grows too. Under the baby teeth, a second set—adult teeth—has been waiting. The story explains that those new teeth slowly push upward, and that’s why a baby tooth begins to wiggle. When it’s ready, the baby tooth falls out, making space for a tooth that’s bigger and stronger. Miluna keeps it gentle: there’s no gross detail, just clear body-friendly language and reassurance that this is normal. It also invites children to notice their bodies with curiosity instead of fear. Curiosity stories like this can support bedtime in a special way: they satisfy the “why” so the mind can settle. They also grow a love for reading and learning—helping kids feel proud of understanding the world inside them.

In One Glance

The story explains why baby teeth fall out. When you were little, you had small ‘baby teeth’ that fit your mouth. As you grow, your jaw grows and adult teeth develop underneath. Adult teeth push up and loosen the baby teeth, making them wiggle until they fall out. This is normal and makes room for stronger teeth.
