[Start Photo Assessment](https://virtualconsultant.online/evaluations/quote) [Compare Costs](https://virtualconsultant.online/costs) ## Dental vs skeletal underbite A dental underbite may be caused mainly by tooth position. A skeletal Class III involves jaw size or position and may need growth modification or surgery depending on age and severity. ## Children and teenagers Early assessment matters because some growing patients benefit from interceptive treatment. Timing depends on growth, bite severity, and specialist assessment. ## Adults Adult underbite treatment may involve braces or aligners for camouflage, or combined orthodontics and jaw surgery for larger skeletal discrepancies. ## NHS and private routes Severe underbite may meet NHS or hospital criteria, especially when orthognathic surgery is involved. Mild cosmetic correction is usually private. ## Useful related pages [Overbite and Underbite Treatment UK](https://virtualconsultant.online/guides/overbite-underbite-treatment-uk) [Jaw Surgery Orthodontics UK](https://virtualconsultant.online/guides/jaw-surgery-orthodontics-uk) [Orthognathic Surgery Timeline UK](https://virtualconsultant.online/guides/orthognathic-surgery-timeline-uk) [Can Braces Fix Jaw Problems UK](https://virtualconsultant.online/guides/can-braces-fix-jaw-uk) This guide is for general information only.

Braces can correct an underbite when the problem is mainly dental, for example where the upper front teeth are tipped back and the lower ones forward, or where a mild skeletal discrepancy can be camouflaged by moving teeth within safe limits. Where the jaw relationship itself is the cause, braces alone cannot change bone position. Growing children may be treated with a protraction facemask or an upper removable appliance while jaw growth can still be influenced, while adults with a marked skeletal Class III usually need combined orthodontics and orthognathic surgery. Can aligners treat underbite? Clear aligners can treat mild dental underbites, particularly where the correction needed is tipping the upper front teeth forwards and the lower front teeth back, usually alongside Class III elastics attached to buttons or precision cuts. They are less predictable where substantial root movement, extraction space closure or heavy anchorage control is required, and those cases are generally handled with fixed braces, sometimes supported by temporary anchorage devices. Aligners cannot change jaw position at all, so a significant skeletal Class III still needs surgical assessment whichever appliance is used. Is underbite treatment available on the NHS? NHS orthodontic treatment is free for under-18s whose case meets the clinical threshold set by the Index of Orthodontic Treatment Need: dental health component grade 4 or 5, or grade 3 with an aesthetic component of 6 or above. An established underbite or reverse overjet usually scores within that range. Adults are essentially never eligible for routine NHS orthodontics, but where jaw surgery is clinically indicated, assessment and treatment can be provided through a hospital orthodontic and maxillofacial pathway after referral. Waiting times and local commissioning arrangements vary considerably. At what age should an underbite be treated? It depends on whether the aim is to influence growth or to correct the result of it. Where the upper jaw is underdeveloped, interceptive treatment with a protraction facemask is most effective in the early mixed dentition, roughly ages seven to ten, because it relies on the sutures still being responsive. Milder underbites caused by tipped teeth can be addressed at almost any age. A genuinely skeletal underbite in a growing patient is usually monitored rather than treated definitively, because the lower jaw is often the last part of the face to finish growing and surgery is planned once growth is complete. What happens if an underbite is left untreated? Many people live with a mild underbite without difficulty, so treatment is not automatic. Where it matters is function and wear. Front teeth meeting edge to edge or in reverse wear unevenly and can chip, chewing efficiency drops when the back teeth do not meet properly, and an asymmetric bite places uneven load on the jaw joints and muscles, which some people feel as fatigue or discomfort. In a growing child a skeletal underbite typically becomes more pronounced rather than less, which is the main argument for assessment early even if active treatment is deferred. How do I know whether my underbite is dental or skeletal? You will not be able to tell reliably by looking, and the distinction decides the treatment. A dental underbite is one where the jaws relate normally but the front teeth are tipped so the lower ones sit ahead, and braces or aligners can usually correct it. A skeletal underbite reflects the size or position of the jaws themselves. Orthodontists separate the two with a clinical assessment plus a lateral cephalometric radiograph, which measures the jaw relationship directly. It is also common to find a combination, where teeth have tipped to compensate for an underlying skeletal pattern and partly disguise it. Explore your options Quick links Not sure where to start?
