Will invisalign help a crossbite?

It can: Depends on the severity and available room. A consultation with a local orthodontist can clear things up for you rather quickly.

It can: Invisalign and correct many (not all) orthodontic issues. Best to visit an orthodontist for a free consult (typical in our industry) and discuss pros/cons vs. Standard braces, treatment options and pricing.

Cause?: If the crossbite is dental, teeth out of position, and relatively mild, clear aligners can help. If crossbite is skeletal, upper jaw too narrow and therefore teeth out of position, clear aligners are not the right '"medicine." clear aligners move teeth, not bone, and are no where near as sophisticated as other types of treatment.
