Children have 20 milk teeth, and they start to erupt (appear) during childhood, usually, around six to eight months of age.

Around the age of 5 to 7 years starts the replacement of milk teeth. It usually continues till 12 to 14 years. The dentures of the permanent teeth lie down between the roots of the primary teeth until the time of replacement. The last permanent teeth to erupt are the third molars, also known as the wisdom teeth.

The first milk teeth appearing are the medial incisors, and it happens around 6-8 months. Not so long after, the lateral incisors erupt. Overall, these teeth appear between 6 to 16 months.
The first molar tooth of the primary dentition can be visible around 12 to 15 months.
The canine teeth emerge around 16 to 20 months.
But the next molar tooth can be visible only at 20 to 24 months of age.

The first permanent teeth appearing usually are the first molar teeth that erupt around the age of 6-7 years. Medial incisors of the primary dentition are being replaced by permanent incisors around age 8, lateral incisors - age 9.

Replacement of the first molar tooth of the primary dentition (premolar tooth in adults) happens around ten years, canine gets replaced around 11 to 13 years, while the second molar tooth appears only around 13 to 16 years. The wisdom teeth - the third and also the last molar teeth - can emerge anytime between 17 to 30 years of age or even later, but usually, it happens till age 24.

NOTE: the 3D model lacks third molars.
