A 12-year-old typically has 32 permanent teeth.
The Development of Teeth in Children
By the age of 12, children have usually completed the transition from their primary ("baby") teeth to their permanent teeth. This process involves the following:
- Losing Baby Teeth: Children initially have 20 baby teeth, which start to fall out around the age of 6.
- Emergence of Permanent Teeth: As baby teeth are lost, they are replaced by permanent teeth.
- Full Set of Permanent Teeth: By the age of 12, all 20 baby teeth are generally lost and replaced with 32 permanent teeth.
| Age Group | Number of Baby Teeth | Number of Permanent Teeth |
|---|---|---|
| Babies / Young Children | 20 | 0 |
| 12 Year Olds | 0 | 32 |
This information comes from the fact that: By 12 years of age, they will have lost all 20 of their baby teeth to make room for their 32 permanent teeth.
