A baby teeth and permanent teeth chart helps parents understand when teeth appear, fall out, and are replaced by adult teeth.
Knowing this timeline makes it easier to spot problems early and support healthy dental development.
This guide explains baby teeth, permanent teeth, and what parents should expect at every stage, using clear timelines and dentist-supported information.
What Are Baby Teeth?
Baby teeth are also called primary teeth or milk teeth. Most children have 20 baby teeth. These teeth help children chew food, speak clearly, and hold space for adult teeth.
Baby teeth usually begin to appear around 6 months of age. Some babies start earlier or later, and that is normal.

Baby Teeth Eruption Timeline
Most baby teeth come in by age 3. Below is a general timeline used by dentists:
- Central incisors: 6–12 months
- Lateral incisors: 9–16 months
- First molars: 13–19 months
- Canines: 16–23 months
- Second molars: 23–33 months
Dentists rely on a baby teeth and permanent teeth chart to track these stages and check for delays or crowding.

Why Baby Teeth Matter
Some parents think baby teeth are not important because they fall out. That is a common mistake.
Healthy baby teeth:
- Guide proper jaw growth
- Keep space for adult teeth
- Support clear speech
- Lower the risk of infection
The American Academy of Pediatric Dentistry explains that early tooth decay can affect permanent teeth later.

When Baby Teeth Fall Out
Baby teeth usually begin to loosen around age 6. The process continues until about age 12 or 13.
Teeth fall out in the same order they came in:
- Front teeth first
- Molars last
If a baby tooth falls out too early due to decay or injury, nearby teeth can shift. Dentists often use a baby teeth and permanent teeth chart to decide if treatment is needed.

What Are Permanent Teeth?
Permanent teeth are adult teeth. Most people have 32 permanent teeth, including wisdom teeth.
Permanent teeth are stronger and designed to last a lifetime with proper care.

Here is the typical schedule:
- 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: 17–25 years (sometimes never)

Some children get teeth later than average. Genetics often plays a role.
2. Early Tooth Loss
Decay or injury can cause early loss. This may affect alignment.

Permanent teeth may look crowded if baby teeth fall out too soon or too late.
