When Do Kids Lose Baby Teeth? A Complete Tooth Loss Timeline
Most kids lose their first baby tooth between the ages of 6 and 7 years. The process continues gradually until around age 12 or 13, when most permanent teeth have erupted. Baby teeth usually fall out in the same order they appeared, starting with the front teeth and ending with the back molars.
At Dr. Gowds Dental Hospitals, one of the most common questions parents ask is whether their child’s tooth loss is happening at the right age. While every child develops differently, understanding the normal baby tooth loss timeline can help parents identify healthy dental development and recognize when a dental evaluation may be needed.
Why Do Children Lose Baby Teeth?
Baby teeth, also known as primary teeth, are temporary teeth that help children:
- Chew food properly
- Learn to speak clearly
- Support facial development
- Maintain space for permanent teeth
As permanent teeth begin developing beneath the gums, they gradually dissolve the roots of the baby teeth through a natural process called root resorption.
Once enough of the root disappears, the baby tooth becomes loose and eventually falls out, allowing the permanent tooth to erupt into its place.
This process is a normal part of childhood dental development.
When Do Kids Usually Lose Their Baby Teeth?
Most children begin losing baby teeth around age 6.
However, it is perfectly normal for tooth loss to begin slightly earlier or later.
Typical Tooth Loss Range
- Early tooth loss: Around 5 years
- Average tooth loss: 6–7 years
- Later tooth loss: Around 7–8 years
In general, children who get their baby teeth earlier may lose them earlier, while those whose teeth erupt later may experience delayed tooth loss.
Baby Teeth Loss Timeline by Age
The order in which baby teeth fall out usually follows the same pattern in which they first erupted.
Lower Central Incisors
Average Age Lost
6–7 years
These lower front teeth are often the first baby teeth to become loose and fall out.
Upper Central Incisors
Average Age Lost
6–7 years
These upper front teeth usually follow shortly after the lower incisors.
For many children, this is the stage when the classic “toothless smile” begins.
Upper Lateral Incisors
Average Age Lost
7–8 years
These teeth sit beside the upper front teeth and are typically replaced by permanent lateral incisors.
Lower Lateral Incisors
Average Age Lost
7–8 years
The lower side incisors usually fall out around the same age as the upper lateral incisors.
First Primary Molars
Average Age Lost
9–11 years
These back teeth help children chew food and are eventually replaced by permanent premolars.
Canines (Cuspids)
Average Age Lost
9–12 years
Canines are important for guiding the bite and supporting proper tooth alignment.
They are generally among the later baby teeth to fall out.
Second Primary Molars
Average Age Lost
10–12 years
These are usually the last baby teeth to be shed before the permanent dentition is complete.
Complete Baby Tooth Loss Chart
| Baby Tooth | Average Age Lost |
| Lower Central Incisors | 6–7 years |
| Upper Central Incisors | 6–7 years |
| Upper Lateral Incisors | 7–8 years |
| Lower Lateral Incisors | 7–8 years |
| First Primary Molars | 9–11 years |
| Canines | 9–12 years |
| Second Primary Molars | 10–12 years |
Most children lose all 20 baby teeth by approximately age 12 or 13.
When Do Permanent Teeth Replace Baby Teeth?
Many parents focus on when baby teeth fall out, but it is equally important to understand when permanent teeth appear.
In most cases, permanent teeth erupt shortly after a baby tooth is lost.
Permanent Tooth Eruption Timeline
| Permanent Tooth | Average Age |
| First Molars | 6–7 years |
| Central Incisors | 6–8 years |
| Lateral Incisors | 7–9 years |
| Canines | 9–12 years |
| Premolars | 10–12 years |
| Second Molars | 11–13 years |
Wisdom teeth, or third molars, usually erupt much later between ages 17 and 25.
Signs a Baby Tooth Is Ready to Fall Out
Many parents wonder whether a loose tooth is normal or if it requires attention.
Common signs include:
Tooth Movement
The tooth begins moving slightly when touched.
Mild Gum Tenderness
Children may notice slight discomfort around the loose tooth.
Progressive Loosening
The tooth gradually becomes more mobile over several weeks.
Visible Permanent Tooth
Sometimes the adult tooth becomes visible underneath or behind the baby tooth before the baby tooth falls out.
Is It Normal for Permanent Teeth to Grow Behind Baby Teeth?
Yes. This condition is commonly known as “shark teeth.”
It occurs when a permanent tooth erupts before the baby tooth has completely fallen out.
This situation is most commonly seen behind the lower front teeth.
In many cases:
- The baby tooth loosens naturally
- The tongue helps guide the permanent tooth forward
- The alignment improves over time
However, if the baby tooth remains firmly in place, a dental evaluation may be recommended.
At Dr. Gowds Dental Hospitals, digital imaging helps determine whether intervention is necessary.
What Happens If Baby Teeth Do Not Fall Out?
Delayed tooth loss is not always a problem, but it should be evaluated when it falls significantly outside normal timelines.
Possible causes include:
Delayed Tooth Development
Some children simply develop more slowly than others.
Missing Permanent Teeth
Certain permanent teeth may never form.
This condition is known as hypodontia.
Impacted Permanent Teeth
A permanent tooth may become trapped beneath the gums or bone.
Retained Baby Teeth
Some baby teeth remain in place longer than expected despite the presence of permanent teeth.
Final Thoughts
If you are wondering when do kids lose baby teeth, the answer is usually between ages 6 and 13, with the first tooth typically falling out around age 6 or 7.
Although every child follows a slightly different timeline, understanding the normal pattern of baby tooth loss helps parents recognize healthy development and identify potential concerns early.
Regular dental checkups, good oral hygiene habits, and professional monitoring can help ensure that permanent teeth erupt properly and support a lifetime of healthy smiles.
