You lose 20 baby teeth in total during childhood.

Quick Scoop: How Many Baby Teeth Do You Lose?

Most kids are born to eventually have 20 “baby” (primary) teeth, and almost all of them will fall out and be replaced by adult teeth.

  • Total baby teeth: 20.
  • Typical age range for losing them: roughly ages 6 to 12–13.
  • These are replaced by a full set of 32 permanent teeth (including wisdom teeth).

So if things follow the usual pattern, you’ll lose all 20.

Which Teeth Fall Out?

Those 20 baby teeth include:

  • 4 central incisors (very front teeth).
  • 4 lateral incisors (next to the front ones).
  • 4 canines.
  • 8 molars.

All of these are usually shed and swapped out for permanent teeth as your jaw and face grow.

Does Everyone Lose All 20?

For most people, yes.

But there are a few exceptions:

  • Some people keep a retained baby tooth into adulthood if an adult tooth never developed underneath.
  • A few kids may have delayed loss or extra teeth and need a dentist to check alignment and spacing.

If someone still has what looks like a baby tooth as an adult, dentists can take X‑rays to see what’s going on under the surface.

Tiny Story-Style Example

Imagine a typical kid named Alex. Around age 6, Alex’s bottom front teeth start to wiggle, then fall out, making room for the first adult teeth to appear. Over the next several years, more front teeth, then canines, then molars follow, until by early teens Alex has dropped all 20 baby teeth and has a nearly full adult smile.
