Underbite Treatments

An Underbite occurs when the upper teeth bite behind of the lower teeth. It occurs in 5% of children and is caused by the following:

  • Small upper jaw (40%)
  • Large lower jaw (40%)
  • Retrusion of upper teeth
  • Protrusion of lower teeth

Treatment options range from correcting the jaw positions surgically, increasing upper jaw forward growth, restricting lower jaw forward growth, and moving teeth to camouflage the skeletal problem.
