- Baby teeth begin to erupt around 6 months and complete by age 3 with 20 teeth.
- Teething symptoms include gum redness, drooling, restlessness, and mild fever.
- Baby teeth act as placeholders for permanent teeth and guide jaw development.
- They start falling out around age 6 and are replaced by age 12–13.
- Regular brushing during the transition protects both baby and permanent teeth.
The development of baby teeth in children lays the foundation for a healthy mouth and jaw structure. This process begins in infancy and continues until around age 12, preparing space for permanent teeth. Therefore, knowing when baby teeth erupt and fall out, their symptoms, and how to care for them helps parents manage this period more easily.

ToggleWhen Do Baby Teeth Erupt?
In babies, baby teeth usually begin to erupt around the 6th month. However, this timeline may vary: in some infants the first tooth may appear as early as 4 months, while in others it may not appear until the first birthday. The first teeth to erupt are usually the lower central incisors. By the age of 3, all 20 baby teeth are typically in place.
Symptoms of Baby Teething
During the teething phase, children may show the following symptoms:
- Increased saliva
- Redness and itching of the gums
- Constantly putting hands or toys in the mouth
- Restlessness and trouble sleeping
- Loss of appetite
- Mild fever (not exceeding 38°C)
The intensity of these symptoms varies among children. During this time, cold teething rings or cold foods wrapped in a clean cloth can provide relief.
How Many Baby Teeth Do Children Have?
A child has a total of 20 baby teeth. These act as placeholders for permanent teeth and support proper jaw development. Baby teeth begin to fall out around the age of 6 to make room for permanent teeth, and this process continues until about age 12–13. The roots of baby teeth gradually dissolve under the pressure of emerging permanent teeth, causing the teeth to loosen and fall out.

When Do Baby Teeth Fall Out?
The order of falling out usually mirrors the order of eruption. The first to fall out are typically the lower and upper central incisors (ages 6–7). These are followed by lateral incisors, canines, and finally molars. The first permanent molars, known as the “six-year molars,” usually erupt in the very back before baby molars fall out.
| Tooth Type | Eruption Age | Shedding Age |
|---|---|---|
| Lower Central Incisors | 6–10 months | 6–7 years |
| Upper Central Incisors | 8–12 months | 7–8 years |
| Lateral Incisors | 9–13 months | 7–9 years |
| First Molars | 13–19 months | 9–11 years |
| Canines (Cuspids) | 16–23 months | 10–12 years |
| Second Molars | 23–33 months | 10–12 years |
In What Order Do Baby Teeth Fall Out?
Baby teeth usually begin to fall out around age 6, although this can vary between children. On average, all baby teeth are lost by ages 12–13.
The typical order of baby teeth falling out is:
- Lower central incisors (6–7 years)
- Upper central incisors (7–8 years)
- Lateral incisors (7–9 years)
- First molars (9–11 years)
- Canines and second molars (10–12 years)
When Do Permanent Teeth Replace Fallen Baby Teeth?
After a baby tooth falls out, it usually takes a few weeks to a few months for the permanent tooth underneath to emerge. This waiting period is completely normal. During this time, it is very important for the child to continue brushing regularly to protect both the remaining baby teeth and the newly erupting permanent teeth.
FAQ About Baby Teeth Falling Out in Children
Do baby teeth fall out at age 5?
Yes, in some children baby teeth may fall out at age 5 due to early development. However, a dental check-up is recommended to confirm whether this is normal.
What is the earliest age baby teeth can fall out?
Typically, the earliest is around 4.5–5 years. If teeth fall out earlier, it may indicate that there is no permanent tooth underneath, so a dental examination is necessary.
Which teeth usually fall out at age 7?
At age 7, the lower and upper central incisors usually fall out. During this period, the first permanent molars also begin to erupt at the back of the mouth.
What happens if a baby tooth falls out and no new tooth grows in?
This may occur if the permanent tooth underneath never developed. In such cases, the dentist will take an X-ray and create an appropriate treatment plan.
Why do some children’s baby teeth fall out late?
Delayed loss of baby teeth can be caused by genetic factors, late development of permanent teeth, very strong baby teeth, or certain oral and dental developmental issues.
Until what age do children lose baby teeth?
Generally, all baby teeth are lost by ages 12–13, and permanent teeth take their place.
