Invisalign vs Fixed Braces UK 2026: Cost, Time & Results Compared
Compare Invisalign and fixed braces cost, treatment time, and results in the UK. Which orthodontic treatment is right for you?
Quick answer
Updated May 2026UK private dental prices depend on the treatment, materials, lab work and follow-up. Comparing the total package cost (consultation, scans, treatment, materials, aftercare) is more useful than the headline starting price for a single tooth or appliance.
- Get a written treatment plan with itemised costs before paying.
- Check whether scans, consultations and follow-up visits are included.
- Verify GDC registration of the treating clinician on the public register.

Cost FAQs
How much do dental implants cost in the UK privately?
UK private dental implants typically cost £1,500–£3,500 per implant, depending on materials, surgeon experience, bone grafting requirements and whether the crown is included. All-on-4 full-arch solutions cost considerably more.
Are private dental prices in the UK regulated?
Private dental fees are not regulated like NHS dental charges. Practices set their own fees. The GDC and CQC regulate clinical standards but not pricing.
What should I compare when choosing a private dentist?
Compare itemised treatment cost, GDC registration, materials and lab supplier (especially for implants, veneers and aligners), warranty terms and follow-up policy.
Can I get cosmetic dentistry on the NHS?
Most cosmetic treatments (whitening, composite bonding, veneers, aligners) are not available on the NHS. NHS dental treatment is focused on maintaining oral health, not cosmetic improvement.
Are dental treatments lower-cost abroad?
Headline prices abroad are often lower but exclude travel, follow-up, aftercare in the UK if complications arise and any potential remediation cost. Compare the all-in cost, not the foreign treatment fee alone.
How this guide was checked

Invisalign or fixed braces — which is the right orthodontic treatment for you? Both options can straighten teeth effectively, but they differ significantly on cost, treatment time, visibility, and what they can treat. This guide compares the two head-to-head using current UK pricing and clinical evidence so you can make an informed decision.
In short
Quick comparison
| Invisalign | Fixed Braces | |
|---|---|---|
| Typical cost | £1,800–£5,500 | £1,500–£5,500 |
| Treatment time | 6–18 months | 12–24 months |
| Visibility | Nearly invisible | Metal brackets visible; ceramic less so |
| Pain level | Mild pressure each new tray | Moderate soreness after adjustments |
| Maintenance | Remove to eat and brush normally | Harder to clean; dietary restrictions apply |
| Best for | Mild to moderate crowding, spacing, adults wanting discretion | Complex bite issues, severe crowding, rotations |
| NHS availability | Almost never | Available for under-18s who qualify (IOTN 4–5) |
Pricing comparison by case complexity
Costs vary depending on the severity of your case. These are typical private UK prices for 2026:
| Case complexity | Invisalign | Fixed metal braces | Fixed ceramic braces |
|---|---|---|---|
| Mild (e.g. 7 aligners / 6 months) | £1,800–£2,500 | £1,500–£2,500 | £2,000–£3,000 |
| Moderate (e.g. 14 aligners / 12 months) | £2,500–£3,500 | £2,000–£3,000 | £2,500–£4,000 |
| Complex (unlimited aligners / 24+ months) | £3,500–£5,500 | £2,500–£3,500 | £3,500–£5,500 |
Fixed metal braces are generally the lower-cost option, particularly for complex cases. Invisalign and ceramic braces are priced similarly at the higher end. Most practices offer 0% finance over 12–24 months, bringing monthly payments to roughly £80–£150 depending on total cost.
For mild cases, Invisalign Lite and short-term fixed braces are priced similarly at around £2,000–£2,500. The cost gap widens for complex cases, where fixed metal braces can be £1,000–£2,000 lower-cost than Invisalign Comprehensive.
When to choose Invisalign
- Appearance matters to you. Clear aligners are nearly invisible. If you work in a client-facing role or simply prefer discretion, Invisalign is the obvious choice.
- Your case is mild to moderate. Invisalign handles crowding, spacing, and minor bite issues effectively. For straightforward cases, treatment time is often shorter than fixed braces.
- You want to eat and drink without restrictions. Aligners are removed for meals, so there are no banned foods — no avoiding toffee, popcorn, or crusty bread.
- You value easier oral hygiene. You brush and floss normally because the aligners come out. Fixed braces make cleaning significantly harder and increase the risk of decalcification (white spots) if hygiene slips.
- You can commit to wearing them 20–22 hours per day. Invisalign only works if you wear the trays consistently. Poor compliance is the single biggest reason for treatment delays or suboptimal results.
When to choose fixed braces
- Your case is complex. Severe crowding, significant bite correction (overbite, underbite, crossbite), and large tooth rotations are still handled more predictably by fixed braces. Brackets and wires give the orthodontist precise three-dimensional control that aligners cannot always match.
- You want the lower cost. Fixed metal braces are the most affordable orthodontic option, especially for moderate to complex cases. If budget is the primary concern, metal braces offer excellent value.
- Compliance is a concern. Fixed braces work 24 hours a day with no patient discipline required. If you are treating a teenager — or you know you are likely to forget to re-insert aligners — fixed braces remove the compliance variable entirely.
- You want NHS-funded treatment. If your child qualifies for NHS orthodontics, the treatment provided will almost always be fixed braces, not Invisalign.
- You need maximum tooth movement. For cases requiring extraction of premolars and significant space closure, fixed braces remain the gold standard.
Can the NHS fund orthodontics?
NHS orthodontic treatment is available only for patients under 18 whose teeth meet the clinical threshold on the Index of Orthodontic Treatment Need (IOTN). The assessment works as follows:
- IOTN grade 1–2: No NHS funding. Treatment is cosmetic and must be funded privately.
- IOTN grade 3: Borderline. NHS funding is sometimes approved but not guaranteed — this depends on local commissioning decisions.
- IOTN grade 4–5: Eligible for NHS orthodontics. These grades indicate a definite or very great need for treatment on clinical grounds.
If your child qualifies, they will pay the NHS Band 3 charge of £332.10 for the entire course of treatment, regardless of how long it takes. This covers all appointments, the braces themselves, and retainers. The treatment will typically be fixed metal braces — NHS orthodontics does not usually cover Invisalign.
Adults are not eligible for NHS orthodontics except in exceptional clinical circumstances, such as cases requiring jaw surgery. In practice, virtually all adult orthodontic treatment in the UK is funded privately.
The verdict
There is no universally better option — the right choice depends on your case, your budget, and your priorities.
Choose Invisalign if your case is mild to moderate, you want a discreet treatment, and you can commit to wearing the trays consistently. You will pay a similar amount to ceramic braces but with far greater convenience.
Choose fixed braces if your case is complex, you want the lowest possible cost, or compliance could be an issue. Fixed metal braces remain the most versatile and affordable orthodontic treatment available.
For many patients with mild to moderate crowding, either option will deliver excellent results. Book consultations with two or three practices to compare treatment plans and pricing — most offer free or low-cost initial assessments.

Frequently asked questions
Which is lower-cost, Invisalign or fixed braces?
Fixed metal braces are generally the lower-cost option, particularly for complex cases — typically £1,500–£5,500 vs £1,800–£5,500 for Invisalign. For mild cases, Invisalign Lite and short-term fixed braces are priced similarly at around £2,000–£2,500. The cost gap widens for complex cases, where fixed metal braces can be £1,000–£2,000 lower-cost than Invisalign Comprehensive.
How long does Invisalign take vs fixed braces?
Invisalign typically takes 6–18 months, while fixed braces (metal or ceramic) take 12–24 months. For straightforward cases, Invisalign treatment time is often shorter than fixed braces — but this depends on the complexity of the case and on consistent 20–22 hour daily wear of the aligners.
What can fixed braces treat that Invisalign cannot?
Severe crowding, significant bite correction (overbite, underbite, crossbite), large tooth rotations, and cases requiring extraction of premolars with significant space closure are still handled more predictably by fixed braces. Brackets and wires give the orthodontist precise three-dimensional control that aligners cannot always match.
Can I get Invisalign on the NHS?
NHS orthodontic treatment is available only for patients under 18 whose teeth meet IOTN grade 4 or 5. If approved, the treatment is the NHS Band 3 charge of £332.10 for the entire course — but it will typically be fixed metal braces, not Invisalign. Adults are not eligible for NHS orthodontics except in exceptional clinical circumstances such as cases requiring jaw surgery.
When should I choose Invisalign over fixed braces?
Choose Invisalign if appearance matters to you (the aligners are nearly invisible), your case is mild to moderate, you want to eat and drink without restrictions, you value easier oral hygiene, and you can commit to wearing the trays 20–22 hours per day. Poor compliance is the single biggest reason for treatment delays or suboptimal results with Invisalign.
When are fixed braces a better choice?
Choose fixed braces if your case is complex, you want the lower cost, compliance is a concern (e.g. for a teenager), you want NHS-funded treatment, or you need maximum tooth movement. Fixed braces work 24 hours a day with no patient discipline required, removing the compliance variable entirely.
