Baby Teeth and Permanent Teeth Eruption Timeline Chart
Parents in Sector 37, Faridabad often come to us with the same question: is my child's tooth coming in on time? Adults sometimes ask a similar thing about a late-erupting wisdom tooth. Tooth eruption follows a fairly predictable pattern, but there is a wide range of what counts as normal. This chart and guide will help you understand the typical timeline and when a delay is worth a dental check.
Baby Teeth (Primary Teeth) Eruption Chart
Babies have 20 primary teeth in total. They usually start appearing around 6 months and finish by about age 3.
| Tooth | Lower Jaw (age) | Upper Jaw (age) |
|---|---|---|
| Central incisor | 6 to 10 months | 8 to 12 months |
| Lateral incisor | 10 to 16 months | 9 to 13 months |
| Canine (cuspid) | 17 to 23 months | 16 to 22 months |
| First molar | 14 to 18 months | 13 to 19 months |
| Second molar | 23 to 31 months | 25 to 33 months |
Most children have all 20 baby teeth by their third birthday. Girls sometimes get teeth a little earlier than boys, but the difference is small.
Permanent Teeth Eruption Chart
Permanent teeth begin replacing baby teeth around age 6 and continue until the late teens or early twenties, when wisdom teeth may appear. Adults have up to 32 permanent teeth.
| Tooth | Lower Jaw (age) | Upper Jaw (age) |
|---|---|---|
| Central incisor | 6 to 7 years | 7 to 8 years |
| Lateral incisor | 7 to 8 years | 8 to 9 years |
| Canine (cuspid) | 9 to 10 years | 11 to 12 years |
| First premolar | 10 to 12 years | 10 to 11 years |
| Second premolar | 11 to 12 years | 10 to 12 years |
| First molar | 6 to 7 years | 6 to 7 years |
| Second molar | 11 to 13 years | 12 to 13 years |
| Third molar (wisdom tooth) | 17 to 21 years | 17 to 21 years |
What Counts as Normal Variation
Tooth eruption timing is not exact. It can be influenced by genetics, nutrition, and how early or late a child was born. As a general rule, variation of 6 months to a year on either side of these averages is usually still considered normal.
- First baby tooth appearing anywhere from 4 to 14 months
- First permanent molars and incisors arriving between 5.5 and 8 years
- Wisdom teeth erupting, staying partially hidden, or never fully coming in
It is also common for teeth to come in slightly asymmetrically, with one side a few weeks ahead of the other. This on its own is rarely a concern.
Signs That May Need a Dental Check
While a wide range is normal, a few patterns are worth having a dentist look at:
- No baby teeth by 15 to 18 months of age
- A permanent tooth that has not appeared a year after the typical age, especially if the baby tooth is still present or already lost
- A noticeable gap of several months between the same tooth erupting on the left versus the right side
- A permanent tooth coming in behind or in front of a baby tooth that has not fallen out
- Pain, swelling, or a bump in the gum without a tooth visibly emerging
These signs do not always mean a serious problem. Sometimes there simply is not enough space, or a baby tooth needs gentle encouragement to fall out. An X-ray at our clinic can usually confirm whether a tooth is developing normally beneath the gum or if there is a blockage.
Why Tracking Eruption Matters
Keeping a rough note of when teeth appear helps us spot patterns early, such as crowding, missing teeth, or teeth coming in at odd angles. Catching these early, often between ages 7 and 10, makes future orthodontic or preventive care simpler and often more affordable.
For families in Sector 37, Faridabad, a routine dental visit around age 1, and again whenever eruption seems off track, is a simple way to stay ahead of any issues. The same applies to adults wondering about a wisdom tooth that seems to be taking its time.

Frequently asked questions
Is it normal for my child's teeth to come in a different order than the chart shows?
Some variation in order is normal and usually not a concern. What matters more is that teeth are appearing within a reasonable age range on both sides of the jaw. If the order seems very unusual or one side is far behind the other, have it checked.
My child is 14 months old with no teeth yet. Should I worry?
Most babies get their first tooth between 6 and 12 months, but some healthy children start later, even after their first birthday. If there is still no tooth by 15 to 18 months, it is worth a dental visit to rule out any underlying cause.
Why do wisdom teeth sometimes never come in?
Many adults simply do not have enough jaw space for wisdom teeth to erupt fully, so they stay partly or fully under the gum. This is common and is usually monitored with X-rays to check they are not causing crowding or infection.
Do adults ever get new permanent teeth after losing one?
No, permanent teeth do not regrow once lost. If an adult tooth is removed or falls out, it needs to be replaced with an option like a bridge, denture, or implant to restore function.
