Baby teeth typically start to come in at around 6 months of age on average, though some infants can start teething as early as 3 or 4 months, and others as late as 12 months or later. The first teeth to usually appear are the lower front teeth (central incisors), followed by the upper front teeth. Most children have all 20 baby teeth by the time they are 2 to 3 years old.
Order and Timing of Baby Teeth Appearance
- Lower central incisors: around 5 to 7 months
- Upper central incisors: around 6 to 10 months
- Lateral incisors (next to front teeth): between 9 and 16 months
- First molars (back teeth): between 13 and 19 months
- Canines (pointed teeth): between 16 and 23 months
- Second molars (backmost teeth): between 23 and 33 months
The baby teeth usually come in symmetrically on the left and right sides.
In summary, teething begins around 6 months, with the lower front teeth usually erupting first, and the process continues until about age 3 when the full set of 20 baby teeth typically emerges.
