The timing of teething can vary. Some babies start getting primary teeth — also called their deciduous, baby, or milk teeth — at just a few months old. Others are still toothless at one year. The stages of tooth eruption generally follow a specific pattern. Here is when your baby’s teeth will most likely come in — and in what order.
Bottom central incisors (the bottom front teeth) at between 4 and 7 months.
Top central incisors (the top front teeth) at between 6 and 8 months.
Top lateral incisors (either side of top front teeth) at between 9 and 11 months.
Bottom lateral incisors (either side of bottom front teeth) at between 10 and 12 months.
First molars (back teeth on top and bottom) at between 12 and 16 months.
Canines (teeth between the top and bottom lateral incisors and first molars) at between 16 and 20 months.
Second molars (the furthest back on top and bottom) at between 20 and 30 months.
Almost all children will have a complete set of 20 baby teeth by the time they’re 2 to 3 years old. Permanent teeth start replacing the primary ones when your child is about six.
