Underbite

Bite Correction

Specialist Planning

# Underbite Treatment Options UK

Underbite is usually corrected with braces or clear aligners when the problem is dental, and with braces combined with jaw surgery when the lower jaw itself sits too far forward. The right option depends on whether the issue is mainly dental, jaw-related, or a combination of both, and on whether jaw growth has finished.

## Dental vs skeletal underbite: why the distinction matters

An underbite (Class III malocclusion) occurs when the lower front teeth sit in front of the upper front teeth. Dental underbite: upper front teeth are tipped too far back, lower front teeth are tipped too far forward, giving the appearance of an underbite despite a normal jaw relationship. This can often be corrected with orthodontics alone. Skeletal underbite: the lower jaw (mandible) is genuinely larger or positioned more forward than the upper jaw (maxilla). Mild skeletal cases can be camouflaged orthodontically; significant skeletal underbites in adults require jaw surgery (orthognathic surgery) for stable correction. A cephalometric X-ray is essential to distinguish these cases.

## What are the treatment options for underbite in growing children and teenagers?

In growing children (under 10 years), reverse pull headgear (facemask) can forward-pull the upper jaw to reduce a skeletal Class III tendency — this works only during growth. In teenagers, functional appliances and orthodontic camouflage (tipping upper teeth forward, lower teeth back) can manage mild to moderate skeletal underbites without surgery. The timing of treatment in teenagers depends on whether the lower jaw has stopped growing — premature treatment before jaw growth is complete risks the skeletal pattern reasserting itself after braces are removed. Growth monitoring before finalising the plan is important.

## What are the treatment options for underbite in adults?

For dental underbite: fixed braces or clear aligners can reposition the teeth to create a positive overjet. For mild skeletal underbite: orthodontic camouflage — deliberately positioning teeth to compensate for the jaw discrepancy — can achieve an acceptable functional and aesthetic result. For significant skeletal underbite: combined orthodontic-surgical treatment (orthognathic surgery) is the appropriate route. This involves pre-surgical orthodontics (12–18 months of brace treatment to align teeth in their respective jaws), jaw surgery under general anaesthesia, and post-surgical finishing orthodontics. Results are stable and the surgical outcome is typically significant.

## Jaw growth completion and treatment timing

The lower jaw is typically the last facial structure to stop growing — often not until the late teens or early twenties, and sometimes later in males. Treating a skeletal underbite orthodontically before jaw growth is complete risks the lower jaw continuing to grow after braces are removed, leading to recurrence of the underbite. Orthodontists often defer definitive treatment for skeletal Class III cases until growth has stabilised, confirmed by serial cephalometric X-rays taken 6–12 months apart. This is not a reason to delay assessment — early monitoring establishes the growth pattern and plans the appropriate intervention timing.

## NHS eligibility for underbite treatment

Significant underbite — particularly with functional bite impairment, anterior crossbite, or skeletal involvement — commonly qualifies for NHS orthodontic treatment in under-18s at IOTN Grade 4 or 5. Hospital-based combined orthodontic-surgical treatment for severe skeletal underbites may also be available on the NHS. NHS waiting lists for standard orthodontic treatment 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 standard orthodontics, though NHS orthognathic surgery assessment is available for significant functional cases.

## What to expect at an underbite consultation

A thorough underbite assessment includes clinical examination of the bite, face, and jaw relationship; a cephalometric X-ray to measure the jaw relationship precisely; dental models or digital scans; and a growth assessment for younger patients. The clinician will be able to advise whether the case is dental, skeletal-mild, or skeletal-significant, and what the realistic treatment options are. For adult skeletal cases, a joint assessment with an oral and maxillofacial surgeon may be arranged. Getting a second specialist orthodontic opinion is entirely reasonable for underbite cases given the complexity and potential for surgical recommendation.

### Frequently Asked Questions

Can braces fix an underbite?

Braces can correct dental underbites and camouflage mild skeletal underbites. Significant skeletal underbites in adults — where the lower jaw is genuinely too large or forward — require orthognathic jaw surgery alongside orthodontic preparation for stable correction. A cephalometric X-ray is needed to determine which category applies.

Can aligners fix an underbite?

Clear aligners can address dental underbites and mild skeletal camouflage cases in adults effectively. They are not appropriate for significant skeletal underbites that require surgical correction. Aligner treatment for underbite cases is most successful when the jaw relationship allows the upper teeth to be moved forward enough to establish a positive overjet without compromising the bite.

Is underbite treatment available on the NHS?

Significant underbite in under-18s — particularly with functional impact or Class III skeletal pattern — commonly qualifies for NHS orthodontic treatment. Severe adult skeletal underbites requiring orthognathic surgery may be assessed for NHS treatment through hospital oral and maxillofacial surgery services. Standard NHS waiting lists in England range from around six months in lower-demand areas to four years or more in many.

At what age should an underbite be treated?

Dental underbites in young children can sometimes be addressed early with simple appliances. Skeletal underbites are often monitored through growth before definitive treatment — the lower jaw must have stopped growing (typically late teens/early twenties) before surgical correction is performed. Growing children with underbite should be assessed, but treatment timing is guided by growth monitoring rather than age alone.

Is jaw surgery always needed for underbite?

No. Mild to moderate skeletal underbites can be camouflaged orthodontically — teeth are positioned to compensate for the jaw discrepancy without surgically moving the jaws. This works best when the discrepancy is not too large and the patient accepts that the underlying jaw relationship remains. Significant underbites with large jaw discrepancy, facial impact, or functional bite problems are the candidates for surgical correction.

How long does underbite treatment usually take?

Dental underbite correction with braces or aligners typically takes 12–18 months, similar to other alignment cases. Orthodontic camouflage for mild skeletal underbite can take 18–24 months because more tooth movement is needed to compensate for the jaw discrepancy. Combined orthodontic-surgical treatment is considerably longer overall — around 12–18 months of pre-surgical orthodontics, the surgery itself, and a further 6–12 months of post-surgical finishing before treatment is complete.
