When do permanent teeth erupt?
The permanent teeth do not erupt until the child is almost 8 years of age. They continue to erupt until the child is about 13 years of age. Girls’ teeth tend to erupt a little earlier than boys’. The only teeth to appear after that are third molars, or wisdom teeth. They usually form between the ages of 12 to 16, and do not erupt until 17 to 20 years of age.
