Orthodontic treatment is a key part of managing the condition, either closing the space or opening it for a restoration.

Hypodontia is the congenital absence of one or more permanent teeth, excluding third molars (wisdom teeth). It is the most common developmental dental anomaly, affecting approximately 5 to 8% of the UK population when wisdom teeth are excluded. Including wisdom teeth, the prevalence rises to around 20 to 25%. Hypodontia can occur in isolation — with no other associated conditions — or as part of syndromes such as ectodermal dysplasia. The condition is largely genetic in origin and often runs in families, though the inheritance pattern can be complex. It may affect a single tooth or multiple teeth; the term oligodontia is used when six or more teeth (excluding third molars) are absent. ## The teeth most commonly missing in hypodontia The pattern of missing teeth is consistent across populations. In the permanent dentition, the teeth most frequently absent are: lower second premolars (the most commonly missing tooth, accounting for around 40% of hypodontia cases), upper lateral incisors (the small teeth flanking the upper central incisors), and upper second premolars. Wisdom teeth are the most commonly missing teeth overall but are not counted in hypodontia classifications. Less commonly, lower central incisors, canines, or first premolars may be absent. The missing teeth are often symmetric (absent on both sides) but not always. In some patients, the corresponding baby (deciduous) tooth is retained into adulthood because no permanent successor exists to push it out. ## Space closure vs space opening — how the decision is made The most fundamental treatment planning question in hypodontia is whether to close the space left by the missing tooth orthodontically, or to open and maintain the space for a future dental restoration such as a bridge or implant. The decision depends on multiple factors: the specific tooth missing and which teeth would be used to close the space; the patient's skeletal pattern and bite (Class II patients may benefit from space closure using the space to retract front teeth; Class III patients generally should not); the size and appearance of adjacent teeth that would be repositioned; the patient's age and growth stage; and patient and family preference. Upper lateral incisor hypodontia is a common scenario where the canine can be moved into the lateral position and reshaped, or the space can be maintained for a later implant or bridge. ## Orthodontic treatment for hypodontia Fixed braces are the most common orthodontic appliance for hypodontia treatment and give the most precise control over tooth positions and space management. Treatment planning must consider the final restorative outcome — spaces that will be restored with implants or bridges need to be the correct width and the adjacent teeth need ideal angulation. Where a retained baby tooth is present, the timing of its extraction must be carefully planned to avoid prolonged space loss. Clear aligners can be used in some hypodontia cases but fixed braces are generally preferred for complex multi-tooth presentations. Treatment is often longer than average — 18 to 36 months — because of the complexity of creating or closing spaces while managing the overall bite. ## Does hypodontia qualify for NHS treatment? Hypodontia generally attracts a high IOTN (Index of Orthodontic Treatment Need) score because congenital missing teeth are explicitly listed in the IOTN dental health component. The absence of any tooth other than a third molar scores at least IOTN 4 (definite need) and multiple missing teeth often score IOTN 5 (very great need). This means most children with hypodontia qualify for NHS orthodontic treatment. NHS treatment is available to under-18s; adults over 18 are not normally eligible. Waiting lists vary by area. Some complex hypodontia cases are treated in specialist NHS orthodontic departments attached to dental hospitals, particularly where restorative or surgical input is also needed. ## Who is on the multidisciplinary team for hypodontia treatment? Hypodontia treatment rarely involves an orthodontist alone. Depending on the treatment plan, the team may include: the general dentist managing ongoing oral health and any retained baby teeth; the orthodontist planning and delivering tooth movement; a restorative or prosthodontic dentist planning and providing final restorations such as bridges, veneers, or composite build-ups; an implant dentist or oral surgeon if implants are planned (implants cannot be placed until growth has completed, typically mid-to-late teens for girls, late teens to early twenties for boys); and a clinical nurse specialist in settings treating patients with syndromic hypodontia. Coordination between these specialists is essential and is best achieved through a combined clinic where possible. ## Useful related pages [Orthodontic Guides Hub](https://virtualconsultant.online/guides) [Types of Braces UK](https://virtualconsultant.online/guides/types-of-braces-uk) [How to Get NHS Braces](https://virtualconsultant.online/guides/how-to-get-nhs-braces) [How Braces Work](https://virtualconsultant.online/guides/how-braces-work-uk) [Get a Virtual Consultation](https://virtualconsultant.online/evaluations/quote) This guide is for general information only.

Yes, hypodontia has a strong genetic component and frequently runs in families. Multiple genes associated with tooth development have been identified, including PAX9 and MSX1. The inheritance pattern is often autosomal dominant with variable expressivity, meaning relatives may have missing teeth but not always the same teeth or the same number. If you have hypodontia, there is a meaningful chance that your children may also be affected, so early dental radiographic screening (typically around age 9 to 10) is sensible. Will my child need a brace for missing teeth? Orthodontic treatment is a key part of hypodontia management for most children. Whether braces are needed and what they will achieve depends on which teeth are missing, the bite, and the chosen treatment approach. If spaces are being closed orthodontically, fixed braces are almost always required. If spaces are being maintained for implants or bridges, orthodontics may still be needed to align the remaining teeth and ensure the space is the correct size and shape. Your orthodontist will assess your child and produce a treatment plan, typically from around age 11 to 13 when permanent teeth have mostly erupted. Can the NHS cover hypodontia treatment? Yes. Hypodontia in under-18s typically qualifies for NHS orthodontic treatment because the IOTN score for missing teeth is usually 4 or 5 (definite or very great need). NHS treatment covers the orthodontic phase. Restorative work such as implants, bridges, and veneers may be covered or partially covered by NHS dentistry depending on clinical need, but implants in particular are not routinely NHS-funded for young adults and are usually a private cost. Your NHS orthodontist will advise on what is covered. What is the difference between hypodontia and oligodontia? Both terms refer to congenitally missing permanent teeth. Hypodontia is used when fewer than six permanent teeth (excluding wisdom teeth) are absent. Oligodontia refers to the absence of six or more permanent teeth excluding third molars. Oligodontia is much less common and is more frequently associated with systemic syndromes such as ectodermal dysplasia. Anodontia, the absence of all teeth, is extremely rare. When should hypodontia treatment start? Assessment should begin early — an orthopantomogram (OPG, or dental panoramic radiograph) taken around age 9 to 10 will show whether permanent teeth are developing normally and identify any that are absent. Active orthodontic treatment typically begins when most permanent teeth have erupted, around age 11 to 13 for most patients. In some cases, early interceptive treatment is indicated — for example, strategic extraction of a retained baby tooth to guide adjacent teeth. The definitive restorative phase (implants or bridges) usually takes place after growth has completed. Can implants replace missing teeth after orthodontics? Yes, dental implants are a common final restoration for patients who have had spaces opened orthodontically to accommodate them. However, implants cannot be placed until growth of the jaws has completed — generally around 17 to 18 for girls and 19 to 21 for boys, though individual variation exists. Placing an implant before growth is complete risks the implant appearing to sink relative to the adjacent natural teeth as the jaw continues to develop. During the wait, a temporary restoration such as a removable denture or adhesive bridge is usually provided to maintain function and appearance.
