A babies molar teeth fall out at around ages 6 to 7 years old and then new molars grow in and are permanent.
Any permanent teeth that grow in including the molars after the child's first set of baby teeth fall out are permanent and will not grow back once they fall out.
The first permanent molars usually erupt between ages 6 and 7 years. For that reason, they often are called the “six-year molars.”
They are among the “extra” permanent teeth in that they don't replace an existing primary tooth.
These important teeth sometimes are mistaken for pri- mary teeth.
Molars are the tough workhorses of human teeth.
Referred to as molars or molar teeth, these are the flat teeth located at the back of the mouth.
They can vary in size and shape but are the largest teeth in the mouth.
Molars are rounded and used for grinding food into easily swallowed pieces.
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.
Humans can only grow two sets of teeth, baby and adult teeth, because of how they evolved over 300 million years ago.
Humans can't grow new teeth, but we're not alone — most mammals can't.
Many reptiles and fish can grow hundreds or even thousands of new teeth.
Geckos grow over 1,000 new teeth in a lifetime.
