Why do we lose our baby teeth?
We lose baby teeth to make room for bigger, stronger grown-up teeth.
Pip’s answer
- We lose baby teeth to make room for bigger, stronger grown-up teeth.
- Your jaw grows bigger, but baby teeth stay small.
- A new tooth grows underneath and gently pushes the baby tooth loose.
- Ooh, those grown-up teeth were hiding in your jaw all along!

For grown-ups
Children have 20 baby (primary) teeth, which fit a small jaw. As the jaw grows, the 32 permanent teeth develop underneath. The roots of the baby teeth dissolve as adult teeth push up, so baby teeth loosen and fall out, usually starting around age 6.
Ask your child: How many baby teeth have you lost so far?
