No jaw growth

Jaw problems can usually be managed well in a growing child with an orthopedic, growth-modifying appliance. However, the same problem for an adult may require jaw surgery. For example, if an adult’s lower jaw is too short to match properly with the upper jaw, a severe bite problem may result. The limited amount that the teeth can be moved with braces alone may not correct this bite problem. Bringing the lower teeth forward into a proper bite relationship could require jaw surgery, which would lengthen the lower jaw and bring the lower teeth forward into the proper bite. Other jaw-width or jaw-length discrepancies between the upper and lower jaws might also require surgery for bite correction if tooth movement alone cannot correct the bite.

Gum or Bone Loss

Adults are more likely to have experienced damage or loss of the gum and bone supporting their teeth (periodontal disease). Special treatment by the patient’s dentist or a periodontist may be necessary before, during and/or after orthodontic treatment. Bone loss can also limit the amount and direction of tooth movement that is advisable.

Worn, Damaged of Missing Teeth

Worn, damaged or missing teeth can make orthodontic treatment more difficult, but more important for the patient to have. Teeth may gradually wear and move into positions where they can be restored only after precise orthodontic movement. Damaged or broken teeth may not look good or function well even after orthodontic treatment unless they are carefully restored by the patient’s dentist. Missing teeth that are not replaced often cause progressive tipping and drifting of other teeth, which worsens the bite, increases the potential for periodontal problems and makes any treatment more difficult.
