A narrow jaw can cause the permanent teeth to erupt into the mouth crooked.
If the upper jaw is crowded an expander will help widen the jaw and make more space.
After several months with an expander the upper jaw is widened.
The expander is removed and the teeth can now be straightened with braces to achieve better alignment.
This is the ideal treatment result at the end of braces.
