A baby can start teething very early, even as early as before birth in rare cases (known as natal teeth), or within the first 30 days after birth (neonatal teeth). More commonly, babies start teething between about 3 to 6 months of age, with many typical cases beginning near 6 months. Some babies may show signs of teething as early as 2 to 3 months, while others may start later, even after 12 months. The first teeth usually to appear are the lower front teeth (central incisors).
Early teething before 6 months is generally not a cause for concern, but teeth erupting very early may have enamel defects. It is advisable to consult a pediatric dentist if teeth appear unusually early.
Key points:
- Earliest teething can occur prenatally (natal teeth) or in the first month (neonatal teeth)
- Typical teething starts between 3 and 6 months
- First teeth usually lower front incisors
- Wide individual variation exists
- Early eruption sometimes requires dental monitoring
