How Many Teeth Do Kids Lose

Losing baby teeth, also known as primary teeth, milk teeth, deciduous teeth, or temporary teeth, is an important milestone in a child’s development. As kids grow, their baby teeth fall out to make room for permanent adult teeth.

It marks the transition from having a mouth full of baby teeth to growing permanent teeth that will last a lifetime. Understanding the timeline, order, and other details around losing primary teeth can help parents know what to expect as their child grows.

Most kids start losing their first tooth around age 5 or 6, but the age range is quite wide, from as early as 4 years old to as late as 7 or 8 years old.

So, how many teeth will a child lose before they have a full set of grown-up chompers? Let’s take a bite out of this topic.

Baby Teeth Basics

Children are born toothless (obviously, except for rare natal teeth). Around 6 months of age, the first set of baby teeth start pushing through the gums. These are known as primary or deciduous teeth. By age 3, kids have a full set of 20 baby teeth:

AreaNumber of TeethTypes of Teeth
Top teeth102 central incisors, 2 lateral incisors, 2 canines, 4 molars
Bottom teeth102 central incisors, 2 lateral incisors, 2 canines, 4 molars
Total Baby Teeth20 

These baby teeth serve important functions, like helping kids chew and speak properly. They also hold space in the jaw for permanent teeth developing under the gums.

How Many Teeth Do Kids Lose?

The simple answer is – kids will lose all 20 of their primary or baby teeth!

These teeth fall out because they are smaller and make room for the larger permanent teeth developing under the gums. By age 13, a child should have lost all baby teeth and have 28 permanent teeth.

Primary Teeth Eruption

A baby’s first tooth generally emerges at the age of 6 to 10 months. As stated, these teeth are known as primary or milk teeth. The eruption of baby teeth lasts until 2.5–3 years of age.

The timeline for primary teeth eruption is as follows:

What Teeth Do Kids Lose?

Around age 5 or 6, baby teeth will start falling out as permanent teeth begin pushing through. This marks the transition from a mouthful of baby teeth to permanent adult teeth.

The first teeth to go are typically the lower central incisors (bottom front teeth). However, every child is different. Here’s the usual order and timeline when kids lose their 20 baby teeth:

  • Darker or yellowish color
