Why it's done

Jaw surgery may help to:

  • Make biting and chewing easier and improve chewing overall
  • Correct problems with swallowing or speech
  • Minimize excessive wear and breakdown of the teeth
  • Correct bite fit or jaw closure issues, such as when the molars touch but the front teeth don't touch (open bite)
  • Correct facial imbalance (asymmetry), such as small chins, underbites, overbites and crossbites
  • Improve the ability of the lips to fully close comfortably
  • Relieve pain caused by temporomandibular joint (TMJ) disorder and other jaw problems
  • Repair facial injury or birth defects
  • Provide relief for obstructive sleep apnea
