In brief: 1-2 months

The bottom teeth (central incisors) usually come in at 6-8 months.
The top teeth come in at 7-9 months. Some babies start teething earlier or later.

In brief: This is variable

Teeth eruption is quite variable in normal babies.
The average quoted is bottom two by 4-6 mo & 1/mo untill all 20 come in. I have seen the bottom two present at birth or not in untill 15 mo. The top 4 are lined up ready to come down next but again eruption is variable. Occasionally i see outer upper teeth come down before the center 4.
