Tooth eruption refers to the process of teeth breaking through the gums and becoming visible in the mouth. This begins in infancy and continues through adolescence. Primary (baby) teeth pave the way for proper jaw development and spacing for permanent teeth, so their eruption timeline is critical.
Primary Teeth (Baby Teeth)
Children typically develop 20 primary teeth by the age of 3. Here’s a general timeline:
| Tooth Type | Eruption Age (Months) | Shedding Age (Years) |
|---|---|---|
| Central Incisors | 6–12 months | 6–7 years |
| Lateral Incisors | 9–16 months | 7–8 years |
| First Molars | 13–19 months | 9–11 years |
| Canines (Cuspids) | 16–23 months | 9–12 years |
| Second Molars | 23–33 months |
10–12 years |
Permanent Teeth (Adult Teeth)
Permanent teeth begin to erupt around age 6 and replace primary teeth. By adolescence, most children will have their permanent teeth, except for the third molars (wisdom teeth).
| Tooth Type | Eruption Age (Years) |
|---|---|
| Central Incisors | 6–8 years |
| Lateral Incisors | 7–9 years |
| Canines | 9–12 years |
| First Premolars | 10–12 years |
| Second Premolars | 11–13 years |
| First Molars | 6–7 years |
| Second Molars | 11–13 years |
| Third Molars | 17–21 years |
Signs of Tooth Eruption
As teeth erupt, your child may experience:
- Tender or swollen gums
- Increased drooling
- Mild irritability or discomfort
- The urge to chew on objects
These are normal signs of teething, but if your child has a fever, rash, or persistent discomfort, consult a pediatric dentist.
