For children, are molars permanent already at the first grow or are they baby teeth and need to fall out?

Primary teeth: The first set of teeth that appear are the primary teeth and will be eventually lost and replaced by the secondary teeth. This exchange starts at about 5.5 years old and can continue into the teens for some children. Your child's dentist should be able to advise you further.

Some: Typically for children under 6 they have two molars per corner of the mouth (total of 8) that will fall out as your child gets older. At around 6 and around 12 Molars will grown behind the existing molars that do not replace any teeth. These next sets will not fall out. The chart attached should help...

Permanent molars: Permanent molars typically comes into the mouth around 6-7 years of age. They do not replace baby molars unless the teeth are so crowded that the permanent molar ended up eating away part of the baby molar roots.

Baby teeth molars: The primary molars typically fall out between ages 9 and 12.

No, baby teeth: the molars in the back to first grow are baby teeth and they will come out on average at age 12 (+-2.5yrs)
