Why does a crossbite need to be treated by an orthodontist?

Crossbites can cause jaw growth problems in growing kids and teens. Crossbites can be linked to a narrow upper jaw and palate, which can cause bite and breathing issues.  Early treatment helps prevent future problems. Crossbites of front teeth can cause tooth chipping or gum problems if untreated.

How is a crossbite treated?

In kids and teens, posterior crossbites (crossbites in the back teeth) are often treated by broadening the upper teeth and jaw. This can be done with special appliances or braces depending on the person. In some teens and adults, crossbites can be treated by braces or Invisalign treatments. Crossbites of front teeth are many times treated by braces or special retainers.
In rare cases, crossbites are so severe that jaw surgery may be needed.
