<p>I’m a dentist. Anatomically, the upper jaw is fixed to the skull, so I can’t imagine how this can be done.</p>
<p>In general, tooth malpositions can be corrected by orthodontics, severe skeletal problems still present after growth is complete need to be corrected surgically. Sometimes orthodontists can help direct growth by using expanders, bionators, herbst appliances or the dreaded headgear if the problem is caught early enough and thereby correct skeletal issues.</p>
