Expansion also can correct a dental cross bite where the back teeth fit inside of the lower back teeth.Not all cross bites, however, require a growth change.

The upper jaw should be 35 to 40 millimeters for us to obtain a stable result. So we actually measure to make sure there is a proper proportionality.
