Orthodontics and Missing Teeth UK: Braces, Implants and Space Management
Orthodontics almost always plays a role when a tooth is missing — either closing the gap by moving adjacent teeth together, or opening and holding the correct space for an implant, bridge, or denture. This guide explains how orthodontics works with restorative dentistry, what interdisciplinary planning involves, and the typical pathways for the most common missing tooth scenarios in the UK.
Should a Missing Tooth Gap Be Closed or Opened?
Space Closure
Orthodontics moves adjacent teeth together to close the gap. No replacement tooth is needed.
No prosthetic replacement needed — fewer long-term costs
Best for premolar extractions and some lateral incisor cases
The adjacent tooth is reshaped cosmetically to mimic the missing tooth
Requires careful planning — not all gaps are suitable for closure
Space Opening
Orthodontics creates or maintains the correct gap for a replacement tooth (implant, bridge, or denture).
Creates ideal gap size and position for implant or bridge
Aligns adjacent and opposing teeth before restoration
Essential if gap has closed partially or teeth have drifted
Implant placement follows orthodontic completion
What Are the Common Missing Tooth Scenarios and Pathways?
Missing upper lateral incisor (congenital or extracted)
| Options | 1. Space closure — move canine forward and reshape it. 2. Space opening — implant or Maryland bridge in the gap. |
| Orthodontic role | Align arch, create correct gap width for implant (5–7 mm), or close space and shape canine to resemble lateral. Decision depends on bite, age, and patient preference. |
| NHS availability | NHS available for children under IOTN criteria; adult NHS unlikely |
| Typical private cost range | £3,000–£7,000+ (orthodontics + implant or bridge) |
Missing lower second premolar (congenital)
| Options | 1. Space closure — extract the retained baby molar and close the space. 2. Space opening — implant or bridge once adult growth complete. |
| Orthodontic role | Moves adjacent molars and premolars to close the space, or maintains space until implant placed (usually age 18–25 after growth complete). |
| NHS availability | NHS available for children under IOTN; complex cases may be hospital-managed |
| Typical private cost range | £2,500–£6,000 depending on chosen restoration |
Adult tooth lost through decay or trauma
| Options | Implant (single or multiple), bridge (conventional or Maryland), removable partial denture, or space closure if adjacent teeth need alignment anyway. |
| Orthodontic role | Uprights tilted adjacent teeth, levels the bite, and creates optimal space dimensions. Orthodontics before implant — implants cannot be moved. |
| NHS availability | Unlikely for adults; extraction and basic denture may be NHS-funded |
| Typical private cost range | £3,500–£8,000 (orthodontics + implant) |
Multiple missing teeth / severe hypodontia
| Options | Multidisciplinary planning involving orthodontist, restorative dentist, oral surgeon, and sometimes maxillofacial team. Implants, bridges, or overdentures. |
| Orthodontic role | Orthodontics prepares the arch — aligns remaining teeth, creates space, ensures root parallelism adjacent to implant sites. |
| NHS availability | NHS hospital-managed for severe cases (oligodontia); complex multidisciplinary care available via OMFS referral |
| Typical private cost range | £10,000–£40,000+ depending on complexity and number of implants |
Retained baby tooth (no permanent successor)
| Options | If baby tooth is healthy — monitor and maintain. If failing — extract and consider options above. |
| Orthodontic role | May be needed to align arch and create space before or instead of tooth replacement. |
| NHS availability | NHS may cover orthodontics for children; adult management varies |
| Typical private cost range | £2,000–£5,000 depending on treatment path chosen |
Does Orthodontics Need to Happen Before a Dental Implant?
Implants and orthodontics are frequently combined in adult treatment. Orthodontics almost always precedes implant placement — the sequence matters:
Orthodontic records and planning
A joint consultation between the orthodontist and restorative dentist establishes whether space closure or opening is the right approach, and what implant dimensions will be needed.
Orthodontic treatment
Braces or aligners align teeth, open or maintain the implant space, and ensure root parallelism (roots of adjacent teeth parallel to receive the implant without interference).
Retention phase — temporary restoration
A temporary tooth (denture, flipper, or Maryland bridge) fills the space during orthodontic treatment. This is important aesthetically and prevents space loss.
Implant placement
Once teeth are in their final positions and the bone has been assessed (CBCT scan), the implant is placed. A healing period of 3–6 months follows.
Crown placement
The final implant crown is placed. The orthodontist and restorative dentist confirm the bite relationship and aesthetics before cementing.
Retention — long-term
Retainers are worn permanently to maintain tooth positions around the implant. Implants cannot be moved — any relapse requires removal and replacement of the crown.
What Is Hypodontia and How Common Is It in the UK?
Hypodontia — the congenital absence of one or more permanent teeth (excluding third molars/wisdom teeth) — affects approximately 5–8% of the UK population. The most commonly absent teeth are upper lateral incisors, lower second premolars, and upper second premolars.
| Severity | Missing Teeth | Typical Approach | NHS |
|---|---|---|---|
| Mild hypodontia | 1–2 teeth missing | Orthodontics + implant or space closure; may involve composite building of adjacent teeth | NHS for eligible under-18s; complex cases via hospital |
| Moderate hypodontia | 3–5 teeth missing | Multidisciplinary orthodontic + restorative plan; combination of space closure and implants/bridges | NHS hospital referral often needed; adult access limited |
| Oligodontia | 6+ teeth missing (excluding wisdom teeth) | Comprehensive hospital-based multidisciplinary care; prosthetic reconstruction; may involve jaw surgery | NHS hospital OMFS service; eligible for NHS-funded complex care |
| Anodontia | All permanent teeth absent (very rare) | Full mouth rehabilitation; implant-supported prosthetics | NHS hospital OMFS service |
When Do Children Need a Space Maintainer?
When a baby (deciduous) tooth is lost early — through decay or trauma — before the permanent tooth is ready to erupt, adjacent teeth drift into the gap. Space maintainers preserve the space to prevent crowding:
A space maintainer is placed immediately (or within weeks) of early baby tooth loss to hold the space open for the permanent tooth.
Fixed band-and-loop or Nance appliance are the most common types for single missing teeth.
Removable space maintainers exist but require compliance — fixed types are usually preferred for children.
NHS-funded for eligible children when clinically indicated.
Typically cost £200–£500 privately if not NHS-funded.
Removed when the permanent tooth begins to erupt into the maintained space.
