Most kids lose all their baby teeth between ages 10 and 12, and by around 12–13 years old the baby teeth are usually completely gone.

Quick Scoop

  • The first baby teeth usually start to fall out around age 5–7, often the lower front teeth first.
  • Baby teeth then loosen and fall out in stages (front teeth, then canines and molars) over several years.
  • Most children have lost their last baby tooth by about age 12, with all permanent non‑wisdom teeth typically in by around 12–13.
  • Wisdom teeth, which are not “baby teeth,” come much later, often between ages 17 and 21 if they erupt at all.

A quick way to think about it

If you imagine a timeline:

  • Early elementary school = starting to lose teeth.
  • Late elementary to early middle school = finishing losing baby teeth and getting a mostly “adult” smile.

So if you’re wondering “what age do you lose all your baby teeth,” the typical answer is: around 12 years old, give or take a year.
