Braces With Missing Teeth UK — Hypodontia, Space Closure and Implant Planning

Can you have braces when you have missing teeth?

Orthodontic treatment is not only possible when adult teeth are missing — it is often essential. Missing teeth change how forces are distributed across the bite and can allow neighbouring teeth to drift, tilt, or over-erupt into the gap. Braces or clear aligners are used either to close the space entirely (space closure) or to position remaining teeth so a dental implant, bridge, or denture can replace the missing tooth in the ideal location (space opening). Your orthodontist and restorative dentist will jointly decide which approach is right for your specific case before treatment begins.

What is hypodontia and how common is it?

Hypodontia is the congenital absence of one or more adult teeth — meaning the teeth simply never developed. It is one of the most common developmental dental anomalies in the UK, affecting roughly 6% of the population when excluding wisdom teeth. The teeth most commonly absent are the upper lateral incisors (the narrow teeth between the front two and the canines), the lower second premolars, and the upper second premolars. Hypodontia ranges from mild (one or two missing teeth) to severe oligodontia (six or more missing teeth), which often requires highly specialist multidisciplinary care. Most people with mild hypodontia are not diagnosed until a dentist takes X-rays in childhood or adolescence, though some cases are identified only in adulthood.

Space closure versus space opening — which approach is right?

When a tooth is missing, the two main orthodontic strategies are space closure — using braces to move neighbouring teeth together so the gap disappears entirely — and space opening — using braces to create or preserve an ideal-sized gap into which a dental implant or bridge can later be placed. Space closure works particularly well for missing upper lateral incisors, where the canine can be moved forward and reshaped to function and look like the lateral. Space opening is preferred when the patient is a good candidate for a dental implant, when closure would compromise the bite, or when the anatomy of the neighbouring teeth makes disguising them as the missing tooth difficult. Both approaches require careful planning and often involve a treatment simulation to help patients understand the likely outcome before committing.

Missing upper lateral incisors — the most common hypodontia case

The upper lateral incisors are the most frequently absent teeth in hypodontia. When one or both are missing, the canines often drift forward into the gap, leaving a visually obvious space or an asymmetric smile. Orthodontists can take two main routes: move the canines back to create space for an implant or composite build-up, or move the canines forward into the lateral position and recontour them cosmetically (with bonding or a veneer) to mimic laterals. The second option avoids the need for implants and produces excellent long-term results in many patients. Which route is best depends on the size and shape of the canines, the existing bite, and whether implants are feasible at the patient's age and bone volume.

Orthodontic treatment before dental implants — what is involved?

Dental implants cannot be placed until jaw growth is complete — usually age 18–20 for women and 20–22 for men. Before then, a temporary tooth (such as a removable partial denture or a bonded Maryland bridge) maintains the space aesthetically. Once growth is complete, the orthodontist uses braces or aligners to position the remaining teeth precisely so the implant can be placed in the correct location and angle. The gap needs to be wide enough to accommodate the implant and the crown that will sit on it — typically at least 6–7 mm for a standard implant. After orthodontic treatment, a retainer holds the space open while the restorative dentist places the implant. Coordination between the orthodontist and the implant dentist is essential to ensure the space is exactly right before orthodontic treatment ends.

Missing premolars and orthodontic planning

Missing lower second premolars are the second most common hypodontia presentation. When the lower second premolar is absent, the overlying baby tooth (lower second deciduous molar) often persists into adulthood — sometimes until the late twenties or early thirties — providing a natural space maintainer. The decision of whether to retain the baby tooth, extract it and close the space orthodontically, or extract it and open the space for an implant depends on the condition of the baby tooth, the patient's age, the existing crowding or spacing, and the restorative plan. In patients with significant crowding, extracting the retained baby tooth and closing the space orthodontically with braces can be an elegant solution that avoids the need for any implants while also relieving the crowding.

Hypodontia and NHS orthodontic treatment

Hypodontia — particularly moderate to severe cases — typically qualifies for NHS orthodontic treatment in the UK under the Index of Orthodontic Treatment Need (IOTN) scoring system. Cases involving multiple missing teeth or significant resulting bite or alignment problems usually score highly on the IOTN dental health component, making them eligible for free NHS treatment for patients under 18. Complex hypodontia cases, particularly oligodontia (six or more missing teeth), are often managed through specialist NHS hospital services involving a multidisciplinary team of an orthodontist, a restorative dentist, and sometimes an oral and maxillofacial surgeon. Adult patients with hypodontia who missed out on NHS treatment as children can access private orthodontic care, and many practices offer payment plans to spread the cost.

Starting the assessment process for missing teeth and braces

The first step is a clinical assessment that includes dental X-rays (usually a panoramic OPG and a periapical series of the relevant areas) to confirm which teeth are truly absent, assess the roots of remaining teeth, and evaluate bone volume at the missing tooth sites. An online photo assessment through Virtual Consultant Online allows a clinician to review your smile and alignment photos remotely and provide initial guidance on the likely treatment approach and options before you attend paid in-person consultations. This is particularly valuable for complex hypodontia cases where understanding the realistic options — and the typical treatment timeline — before committing to the process helps patients make informed decisions.
