Baby Teeth and Permanent Teeth Timeline: A Guide for Parents
Parents in Sector 31 often ask us the same question in different ways: "Is my child's tooth coming in late?" or "Should this baby tooth have fallen out by now?" Tooth development follows a fairly predictable pattern, but there is a healthy range of normal. This guide lays out the general timeline for both baby teeth and permanent teeth so you can track your child's progress with confidence.
Baby Teeth (Primary Teeth) Eruption Timeline
Most children get their first tooth between 6 and 10 months of age, though some babies surprise their parents as early as 4 months or as late as 12 months. By around age 3, most children have a full set of 20 baby teeth.
| Tooth | Typical Eruption Age |
|---|---|
| Lower central incisors | 6-10 months |
| Upper central incisors | 8-12 months |
| Upper lateral incisors | 9-13 months |
| Lower lateral incisors | 10-16 months |
| First molars | 13-19 months |
| Canines (cuspids) | 16-23 months |
| Second molars | 23-33 months |
Girls sometimes get their baby teeth slightly earlier than boys, but the difference is small. What matters more is that teeth appear in roughly the right order, not the exact month.
When Do Kids Lose Baby Teeth?
Baby teeth usually start falling out around age 6, beginning with the lower central incisors, and the process continues until around age 12 or 13. This generally follows the same order in which the teeth erupted.
| Tooth | Typical Age Lost |
|---|---|
| Lower central incisors | 6-7 years |
| Upper central incisors | 6-7 years |
| Lateral incisors | 7-8 years |
| First molars | 9-11 years |
| Canines | 9-12 years |
| Second molars | 10-12 years |
Permanent Teeth Eruption Timeline
As baby teeth fall out, permanent teeth take their place. The first permanent molars, often called "6-year molars," usually arrive without replacing any baby tooth, right behind the existing baby molars.
| Tooth | Typical Eruption Age |
|---|---|
| First molars (6-year molars) | 6-7 years |
| Central incisors | 6-8 years |
| Lateral incisors | 7-9 years |
| Canines | 9-12 years |
| First premolars | 10-12 years |
| Second premolars | 10-12 years |
| Second molars (12-year molars) | 11-13 years |
| Third molars (wisdom teeth) | 17-21 years |
By around age 13, most children have all their permanent teeth except the wisdom teeth, which arrive much later and do not always need to stay, as we cover in our article on wisdom tooth pain and removal.
What Counts as Normal Variation
A difference of a few months from these charts is common and rarely a cause for concern. Genetics, jaw size, and general growth patterns all play a role. Things we do watch more closely include:
- A tooth that is more than 12 months late compared to its expected age
- Teeth coming in noticeably crowded or at odd angles
- A baby tooth still present long after the permanent tooth should have erupted
- Gaps that seem unusually wide or narrow for the child's age
Tracking Your Child's Dental Growth
Regular dental visits every six months let us monitor eruption patterns, catch early signs of crowding, and guide habits like thumb sucking that can affect tooth position. For families in Sector 31, Gurugram, keeping a simple record of when each tooth appears or falls out can also help your dentist spot patterns worth discussing.
At The Tooth Atelier, we see children at every stage of this journey, from their very first tooth to their last baby tooth falling out. If something about your child's timeline feels off, an exam can usually settle the question quickly and put your mind at ease.

Frequently asked questions
Is it normal for my child's teeth to come in earlier or later than the chart?
Yes, a few months earlier or later is usually normal. Every child's growth pattern is slightly different. If a tooth is delayed by more than a year compared to the chart, it is worth getting checked.
What should I do if my child's baby tooth is loose but not falling out?
Gentle wiggling with clean fingers or encouraging normal chewing is usually enough. Avoid forcing it out. If it stays loose for several weeks without progress, or if it seems infected or painful, visit a dentist.
Why do some permanent teeth come in behind baby teeth that haven't fallen out yet?
This is called shark teeth and is fairly common, especially with lower front teeth. The baby tooth root may not have resorbed properly. A dentist can check if the baby tooth needs to be removed to guide the adult tooth into place.
At what age should my child have their first dental checkup?
It is best to bring your child in by their first birthday or within six months of their first tooth appearing, so we can track development from the start.
