How do Children’s teeth erupt and fall out?

How-do-Childrens-teeth-erupt-fall

Babies begin to get their milk teeth by six months, and by the time they turn two years old, all the milk teeth come out. This is known as the deciduous teeth phase. Milk teeth eventually start falling out by the age of 6 years and are replaced by their permanent counterparts. There are 20 milk teeth, 10 in the upper jaw and 10 in the lower, whereas they are 32 permanent teeth, 16 in each jaw. In permanent dentition, premolars and third molars also erupt, which are not present in the milk dentition. 

The first milk teeth to fall out happens to be the upper and lower front teeth. This is followed by canines, the first molar, and the second molar. Children will lose all their baby teeth by the age of 12 years. Girls usually mature faster and tend to lose their teeth earlier than boys. This is also true for eruption. 

The first teeth permanent teeth to erupt happen to be the first molar, and the last teeth happen to be the third molar if they erupt at all. Below is the timeline for both the upper and lower teeth.
