Detailed explanation-1: -Next, the top four front teeth emerge. After that, other teeth slowly begin to fill in, usually in pairs–one each side of the upper or lower jaw–until all 20 teeth (10 in the upper jaw and 10 in the lower jaw) have come in by the time the child is 2 ½ to 3 years old.
Detailed explanation-2: -Wisdom teeth are the third set of molars that grow in on both sides of the mouth, top and bottom. They usually erupt when a person is between the ages of 17 to 21 – when they are perhaps a little “wiser” than when the majority of their adult teeth previously arrived.
