Braces for Overbite UK: Deep Bite Treatment Guide

Fixed braces can correct most dental overbites fully. For skeletal overbites (caused by jaw position), braces alone may improve but not fully resolve the bite — functional appliances during the growth phase or jaw surgery in adults may be needed for complete correction. A lateral cephalometric X-ray and specialist assessment are needed to determine whether your overbite is dental or skeletal and what the realistic outcome of treatment is.

Fixed braces are generally more predictable for deep or complex overbites because they provide better three-dimensional control, particularly for intrusion of lower front teeth and extrusion of back teeth. Clear aligners work well for mild to moderate dental overbites, especially with attachments and elastic wear. For the most complex cases, fixed braces remain the gold standard. A GDC specialist orthodontist can advise which is most appropriate for your specific bite.

NHS orthodontic treatment for adults is not routinely available for dental overbites. Exceptions include cases linked to orthognathic surgery (jaw surgery), which may be NHS-funded if the surgical component is clinically indicated. Adults seeking overbite correction for cosmetic or functional reasons will need private treatment. Check with your GDP for a referral assessment if you believe your case may qualify for NHS surgical intervention.

Mild overbite correction as part of overall alignment: 12–18 months. Moderate to significant deep bite correction: 18–24 months. Complex cases with functional appliances before fixed braces: 24–36 months total. Skeletal cases requiring jaw surgery: treatment may span 2–4 years including surgical planning. Only a clinician who has examined you and taken records can give an accurate estimate for your specific case.

Overbite relapse is common without proper retention. The lower front teeth have a strong tendency to over-erupt after treatment. A fixed retainer bonded to the lower front teeth combined with nightly removable retainers is the most effective way to maintain overbite correction. Your orthodontist should specifically discuss retention for the bite — not just for tooth alignment — before treatment ends.

A bite turbo is a small ramp of composite resin bonded to the biting surface of a lower premolar or to the inner surface of an upper incisor. In deep overbite cases, the lower teeth bite so far up behind the upper teeth that they would contact and dislodge the lower brackets as soon as they were fitted. Bite turbos create a small stop that prevents the back teeth from fully closing, giving the orthodontist room to level the bite without constant bracket breakages. They feel strange initially and make biting into food more difficult for the first few weeks, but are a standard and effective part of deep bite treatment. Most patients adapt within two to four weeks.

A very deep overbite can cause the lower front teeth to bite into the palate (roof of the mouth) when the back teeth come together, causing soft tissue trauma and ulceration. In severe cases this can cause significant gum damage over time. It can also accelerate tooth surface loss on the upper palatal surfaces and lower incisor edges through occlusal wear. While a moderate overbite that does not cause tissue contact may not urgently require treatment, a very deep bite with palatal trauma is a clinical — not just cosmetic — reason to seek orthodontic assessment, and this severity of overbite typically qualifies for NHS treatment in under-18s.

Adults can often correct a dental deep bite without surgery, using fixed braces or aligners to intrude the front teeth, level the arches and change the angle of the incisors. What braces cannot change once growth has finished is the jaw relationship itself, so an adult with a markedly set-back lower jaw can have the bite improved by moving teeth but not the underlying facial profile. This approach is called orthodontic camouflage and suits many people. Where facial appearance or jaw function is the main concern, ask for an orthognathic assessment.

For an overbite with a skeletal component, the best time is usually the pubertal growth spurt — roughly age 10 to 13 in girls and 11 to 14 in boys — when a functional appliance can use remaining jaw growth. For a purely dental deep bite, treatment can start once the permanent teeth have come through, typically from 12 to 14. Adults can be treated at any age, but skeletal problems cannot be changed without surgery once growth is complete. Under-18s who meet the IOTN threshold can have NHS treatment at no cost.

Many overbite cases with a large overjet use Class II elastics, small rubber bands stretched from the upper canine area to the lower molars on each side. They pull the lower teeth forward and the upper teeth back, reducing both overjet and overbite. Elastics only work if worn as instructed, usually around 22 hours a day and changed several times daily; part-time wear gives unpredictable results and extends treatment. Growing patients who struggle with compliance may be offered a fixed functional appliance such as a Herbst instead.
