Crossbite palate expander before and after
A palate expander can widen a narrow upper jaw and correct some crossbites, but the change depends on growth, jaw anatomy, and the type of crossbite.
How much can a palate expander change a crossbite?
A palate expander can widen a narrow upper jaw and correct some crossbites, but the change depends on growth, jaw anatomy, and the type of crossbite.
What does a crossbite mean for the upper and lower teeth?
A crossbite occurs when an upper tooth bites inside a lower tooth. An expander applies controlled force across the upper arch through an appliance attached to teeth.
What happens during an assessment for a palate expander?
The orthodontist examines the bite and may use photographs, scans, and X-rays. Keep the appliance clean, activate it only as prescribed, and attend adjustment visits.
When does a palate expander problem need prompt review?
Seek review for severe pain, a loose or broken appliance, persistent ulceration, or inability to follow the activation instructions.
What should I ask about crossbite correction and retention?
Ask whether the crossbite is skeletal, dental, or functional, how retention will work, and whether the photographs show jaw correction or tooth movement.
