Children typically start losing their primary lower central incisors (lower front baby teeth) when they are 6-7 years old. This may vary from child to child and they may start losing teeth earlier or later than this.

Hello,

A typical age for baby teeth to start falling out is around 6 years old, the lower two central teeth. However, I’ve seen some start as early as 5 or as late as 7. It is normal.
Thank you.
