The Herbst appliance, uses steady , continuous force to slow down the development of the upper jaw, and at the same time encourage forward growth of the mandible. Your concerns should be discussed with your treating orthodontist.

By definition, the Herbst appliance is designed to move teeth to place them in a better position, and will always affect your face and jaws. If The results are not satisfactory, you should talk to the orthodontist who placed it. There may be other alternatives for further treatment that may help. Good luck.
