Eruption Schedule

Children’s teeth begin forming before birth. As early as 4 months, the first primary (or baby) teeth to erupt through the gums are the lower central incisors, followed closely by the upper central incisors. Although all 20 primary teeth usually appear by age 3, the pace and order of their eruption varies.

Permanent teeth begin appearing around age 6, starting with the first molars and lower central incisors. This process continues until approximately age 16 with the exception of the wisdom teeth, which are frequently impacted.

Adults have up to 32 teeth including the third molars (or wisdom teeth).

As shown on the eruption video, the blue teeth are the baby teeth and the white teeth pushing through are the permanent teeth.

The numbered line along the bottom of the video coincides with the age of eruption.
