Crossbite

Bite Correction

Treatment Options

# Crossbite Treatment Options UK

Crossbite is usually corrected with a palatal expander in growing children and with fixed braces or clear aligners in adults, with surgical expansion reserved for severe skeletal cases. The right option depends on which teeth are involved, whether the upper arch is narrow, and how much movement is needed.

## Types of crossbite and how they differ

A crossbite occurs when one or more upper teeth sit inside (behind) the lower teeth when biting, rather than outside. Anterior crossbite affects the front teeth — one or more upper front teeth bite behind lower front teeth. Posterior crossbite affects the back teeth — upper back teeth sit inside the lower back teeth on one or both sides. Unilateral posterior crossbite (one side only) often involves a jaw shift on closing that can contribute to jaw asymmetry over time if untreated. Bilateral posterior crossbite (both sides) is often related to a narrow upper arch. The type, position, and cause all influence which treatment approach is appropriate.

## Causes of crossbite

Posterior crossbite is commonly caused by a narrow upper jaw (maxilla) relative to the lower jaw, which may be developmental or genetic. Prolonged thumb sucking can contribute by narrowing the upper arch. Anterior crossbite can result from a single upper tooth that has erupted in an incorrect position, or from a skeletal pattern where the lower jaw is positioned forward relative to the upper (Class III relationship). The cause matters because dental crossbites (single tooth in wrong position) are managed differently from skeletal crossbites (jaw relationship).

## Treatment options for crossbite

Anterior crossbite of a single tooth: often corrected with fixed braces or a simple removable appliance that tips the tooth forward. Posterior crossbite in growing children: palatal expanders (removable or fixed rapid palatal expanders — RPE) widen the upper arch to correct the crossbite before or alongside brace treatment. This is most effective during growth. Posterior crossbite in adults: dental camouflage with fixed braces is possible for mild cases; surgical expansion (SARPE) or jaw surgery may be needed for significant skeletal discrepancy. Aligners can address mild crossbites, particularly dental ones.

## Why crossbite in children may benefit from early treatment

Posterior crossbite with a jaw shift is often treated earlier than most orthodontic conditions — ideally while the child is still growing and the upper arch suture is responsive to expansion. Treating a crossbite with jaw shift at age 8–10 can correct the jaw deviation before it becomes habitual or structural. Early expansion also creates space for incoming permanent teeth, potentially reducing crowding. This is one of the few orthodontic presentations where early intervention is generally favoured rather than waiting for all permanent teeth.

## Aligners for crossbite correction

Clear aligners can address anterior dental crossbites and mild posterior crossbites in adults effectively. They are less suitable for significant skeletal crossbites, bilateral narrow arches needing substantial expansion, or cases in growing children where expansion appliances are more efficient. For complex posterior crossbite, fixed expansion appliances followed by fixed braces or aligners is the standard pathway.

## NHS eligibility for crossbite treatment

Crossbite with a jaw shift (mandibular displacement) commonly qualifies for NHS orthodontic treatment in under-18s at IOTN Grade 4. Single-tooth anterior crossbite causing significant displacement also typically qualifies. NHS waiting lists in England vary widely by region – around six months in lower-demand areas, but four years or more in many. Adults are not routinely eligible for NHS orthodontic treatment, but significant functional crossbite in adults may be considered for hospital referral.

### Frequently Asked Questions

Can crossbite be fixed with braces?

Many dental crossbites can be corrected with fixed braces. Posterior crossbites involving a narrow upper arch usually need palatal expansion first (with an expander appliance), followed by braces. Skeletal crossbites in adults with significant jaw width discrepancy may need surgical expansion alongside orthodontics.

Can aligners fix crossbite?

Clear aligners handle some crossbites but not all. They work reasonably well for anterior dental crossbites — where one or two front teeth bite inside the opposing teeth — and for mild posterior crossbites in adults where only modest widening is needed. They are a poor choice where both sides of a narrow upper arch need significant expansion, because meaningful skeletal widening requires a fixed expander or, in adults, sometimes surgically assisted expansion. In children, expansion appliances are faster and more predictable than aligners. A clinician assessment with full records confirms which route suits your case.

Should crossbite be checked early?

Yes — particularly posterior crossbite with a jaw shift in children. This is one of the few orthodontic presentations where early intervention (around age 8–10) is actively beneficial rather than simply watchful waiting. A jaw shift that is present throughout growth can contribute to facial asymmetry.

What happens if crossbite is not treated?

Untreated posterior crossbite with a jaw shift can contribute to jaw asymmetry and uneven tooth wear. Single-tooth anterior crossbite can cause gum recession on the affected lower tooth from traumatic biting force. Functional concerns — chewing difficulty, jaw joint effects — are more common with posterior crossbite involving both sides.

How long does crossbite treatment take?

A simple single-tooth anterior crossbite may correct in 3–6 months with simple appliances. Posterior crossbite expansion with a fixed palatal expander typically takes 3–6 months of active expansion followed by fixed brace treatment for alignment. Complete crossbite treatment in a teenager including alignment typically takes 12–18 months total. Adult crossbite correction varies by complexity.

Will I need retainers after crossbite treatment?

Yes — retainers are essential after crossbite correction to maintain the bite position achieved during treatment. The bite has been changed by orthodontic movement, and without retention the teeth and bite can shift back. Most orthodontists recommend fixed wire retainers behind the front teeth plus removable retainers worn nightly after crossbite treatment.
