Do molars fall out and grow back?
The first permanent teeth to come in are the 6 year molars (first molars), sometimes called “extra” teeth because they do not replace baby teeth. The baby teeth that are acting as placeholders then typically fall out in the sequence in which they erupted, as they are replaced with their permanent counterparts.
Do you need your back molars?
1.)
Each one plays an important role in chewing and grinding up food. Back teeth encourage an even bite, which reduces strain on the jaw and extra pressure on the front teeth. Over time, eating with a missing back molar can wear down the remaining teeth and cause them to chip or crack.

Why is my daughter’s tooth not growing?
The most common reason as to why a permanent tooth doesn’t erupt is because there isn’t enough space for it. Permanent teeth at the front of the mouth are wider than the primary teeth that they’ll replace so if there’s not enough space, the permanent tooth won’t have room to come in.
