| Sets of Teeth |
Everyone
grows two sets of teeth: a first (primary), or baby teeth, and a second,
or permanent set. Nature has given us two sets.
Teeth small enough for a child would be too little for use by an adult.
When we are born we have, hidden in
our jaws, the beginning of all our teeth. Our first set of teeth begin to
push up through the gums when we are about 6 months old. Most of us have
all our baby teeth at the age of 2 ½ or 3.
In the meantime, our second set is
forming in the jaws. At about the age of 6 our baby teeth become loose
and fall out, and permanent teeth grow in their place. As the jaws grow larger, more teeth
push, up until finally we have our full set of 32 permanent teeth.
The last four teeth are slow to
grow. They do not push up until we are nearly grown up. Bu that
time we are supposed to have gained some wisdom, so these last teeth are called
“wisdom teeth.”
