Why gap-closing costs vary
Small spacing in otherwise well-aligned teeth may be a short aligner case with minimal movements — at the lower end of the cost range. Multiple gaps, bite involvement, tooth-size discrepancies, or missing teeth management significantly increase complexity and cost. Cases combining orthodontic space closure with restorative work (bonding, veneers, implants) involve two sets of fees — one for orthodontics, one for the restorative phase.
How much does gap treatment cost in the UK (2026)?
Clear aligners for simple spacing: £1,500–£3,000. Clear aligners for moderate or multiple gaps: £2,500–£4,000. Fixed braces for spacing with bite correction: £1,800–£4,000. Composite bonding to reshape teeth after orthodontic closure: £150–£400 per tooth. Implant to replace a missing tooth in a maintained gap: £2,500–£3,500 per tooth. These ranges overlap and depend on case complexity — an online assessment can help identify which cost bracket applies to your case.
Should gaps be closed with braces, aligners, or cosmetic treatment?
Many spacing cases are best addressed orthodontically — moving the teeth to close the gaps provides a stable result with good retention. Some cases need combined planning: orthodontic closure followed by composite bonding or veneers to correct proportions, or orthodontic space maintenance followed by an implant or bridge. If your main concern is a midline gap, composite bonding alone (without orthodontics) is sometimes offered as a quicker option — but the gap frequently recurs unless the underlying cause is addressed. Combined orthodontic and restorative plans deliver more stable long-term results.
What to check in your quote
Confirm retainers are included — gaps are highly prone to relapse without long-term retention. Ask about refinements (for aligner cases). Check whether any restorative treatment is a separate quote from a separate provider. If the plan involves space maintenance for a future implant, confirm the timeline and cost of both the orthodontic phase and the restorative phase in writing.
NHS eligibility for gap treatment
Significant spacing — a large central diastema or multiple gaps from missing teeth — may qualify for NHS orthodontic treatment in under-18s who score IOTN Grade 4 or 5. NHS waiting lists vary widely by region – around six months in lower-demand areas, but four years or more in many parts of England. Adults are not routinely eligible. For adults or those who do not want to wait, private treatment is available — an online photo assessment gives indicative costs before paid consultations.
Getting a gap treatment cost estimate online
A clinician-reviewed photo assessment can identify likely treatment direction (orthodontic closure, combined plan, or restorative) and provide cost ranges before you attend paid consultations. This is especially useful for spacing cases because the range of options is wide and knowing the likely approach in advance helps you compare providers on a like-for-like basis.
