Milk teeth

How all 20 primary teeth emerge between roughly six and twenty-nine months.

Eruption happens in overlapping waves

The first lower central incisors usually appear near six months. Other incisors follow, then first molars and canines, while the second molars complete the primary set near the end of the second year.
