Do childrens molars fall out and get replaced?

Yes, children's molars fall out and get replaced.

Primary teeth, also known as baby teeth or milk teeth, are the first set of teeth that develop in humans. They begin to erupt in the mouth at around 6 months of age and are usually all in place by the age of 3. There are 20 primary teeth in total: 10 in the upper jaw and 10 in the lower jaw.

Primary molars are the four large teeth located at the back of the mouth, two in each jaw. They erupt between the ages of 1 and 3 years. Primary molars are important for chewing and biting, and they also help to hold space for the permanent teeth that will eventually replace them.

Around the age of 6, the primary molars will begin to loosen and fall out. This process is known as exfoliation. Exfoliation usually occurs in the same order as the teeth erupted, starting with the molars and ending with the incisors (front teeth).

As the primary molars fall out, they will be replaced by permanent molars. Permanent molars are larger and stronger than primary molars, and they have deeper roots. The first permanent molars erupt at around the age of 6, and the last permanent molars erupt at around the age of 12.
