Palatal Expander for Wider Arch

I have seen patients even as old as 26 simply use orthodontic methods to expand arches, without surgery or any complicated treatment.  That does not mean it will work with everybody and MAY not be appropriate for you at 22.  Some believe that the sutures at the roof of the mouth have fused by your age, but recent studies are proving this long held belief to be false.

You may find that your situation is minor and simple Invisalign or traditional brackets is all you need.

At your age, simple arch widening with a palatal expander is very difficult ( unless it is only a minor amount needed), usually what happens is that your teeh flare out and the bone in the palate does not widen, this can lead to other problems.  A surgicvally assisted palatal expansion can be performed using a palatal expander and a relativele minor surgery to make some cuts in the bone to facilitae the widening where you want it to occur.  The other option is full orthognathic jaw surgery to move the jaw where the ideal position should be.  This is the most invasive, but it is the quckest.

As a child you are able to expand the palate while the bone is growing and maleable,but as an adult its tricky and not recommended. If I were you I would get orthodontics or Invisalign to widen the teeth out and see how you like it. Surgery seems a bit harsh for what you are wanting...
