Can Braces Fix a Crossbite?
Yes — fixed braces are one of the most common and effective treatments for crossbite. They can move individual teeth or groups of teeth into proper alignment over the course of treatment.
The suitability of braces depends on the type of crossbite, whether the problem is dental (tooth position) or skeletal (jaw position), and how much growth remains. For mild to moderate dental crossbites, braces are usually the primary treatment. For significant skeletal crossbites in adults, orthognathic (jaw) surgery may be required alongside braces.
Early treatment in children is often preferred — expanding the upper arch before growth is complete is easier and avoids more complex intervention later.
Types of Crossbite and How Braces Help
Posterior Crossbite
One or more upper back teeth sit inside the lower back teeth. Often treated with a palate expander in growing patients, followed by fixed braces to refine alignment.
Anterior Crossbite
One or more upper front teeth sit behind the lower front teeth. Fixed braces can tip or move the upper teeth forward. Early intervention gives the best result.
Dental Crossbite
The jaw is in the correct position but individual teeth are out of alignment. Braces alone are usually sufficient to correct a dental crossbite.
Skeletal Crossbite
The underlying jaw position causes the crossbite. In adults, braces alone may not fully resolve it. Jaw surgery combined with braces is sometimes needed for a stable result.
What Happens During Crossbite Treatment with Braces?
Treatment typically starts with a full orthodontic assessment, including photographs, impressions or digital scans, and sometimes X-rays to assess the jaw and bone structure.
For growing patients with a posterior crossbite, a removable or fixed palate expander may be used first to widen the upper arch. Fixed braces are then placed to align the teeth and correct the bite.
For adults, fixed braces work on the teeth directly. If the crossbite has a skeletal component, your orthodontist may refer to a maxillofacial surgeon to discuss whether jaw surgery is part of the plan.
Risks of Leaving a Crossbite Untreated
A crossbite that is not treated can worsen over time. Tooth-on-tooth contact at the wrong angle causes uneven wear, increased sensitivity, and a higher risk of chipping.
Jaw shifting to accommodate a crossbite can lead to facial asymmetry, jaw muscle strain, and temporomandibular joint (TMJ) problems.
The earlier a crossbite is assessed and treated, the simpler and less expensive the intervention tends to be.
