Costs in the UK (2026)
| Treatment | Typical Private Price | Notes |
|---|---|---|
| Invisalign Express / Lite | £1,800 – £3,000 | Mild crowding/spacing; fewer aligners |
| Invisalign Full / Comprehensive | £3,200 – £4,800+ | Moderate cases; attachments, IPR, elastics as needed |
| Fixed metal braces | £2,500 – £4,000 | Reliable, versatile; visible brackets |
| Ceramic (tooth-coloured) braces | £3,000 – £5,000 | More discreet; slightly higher friction |
| Lingual braces (inside teeth) | £5,500 – £9,000+ | Most discreet but technical and pricey |
| Retainers (Vivera/Essix, per set) | £150 – £400 | Budget for lifetime retention |
Prices vary by region, case complexity, clinician experience and aftercare. Confirm inclusions: records, attachments, refinements, breakages, retainers, reviews.
Treatment speed
| Option | Typical Duration | Why it varies |
|---|---|---|
| Invisalign | 4–18 months | Case complexity, aligner wear discipline (22 hrs/day), refinements |
| Fixed metal/ceramic braces | 12–24 months | Complex tooth movements; appointment intervals |
| Lingual braces | 12–24+ months | Technical demands; speech/tongue adaptation |
What each is best at
| Concern | Invisalign | Fixed Braces |
|---|---|---|
| Mild–moderate crowding/spacing | Strong | Strong |
| Bite changes (overbite/underbite/crossbite) | Good with elastics/attachments (case-dependent) | Often stronger for complex bite correction |
| Severe rotations/impactions | Possible with experienced providers, sometimes slower | Typically more predictable |
| Discretion | Near-invisible | Metal visible; ceramic more discreet; lingual invisible |
| Oral hygiene | Aligners removable; easier brushing | Needs careful cleaning around brackets/wires |
Comparing wider private healthcare?
See policies that cover diagnostics, hospital care and specialist access (dentistry usually excluded).
Who’s a good candidate?
- Invisalign: adults/teens with mild–moderate crowding, spacing or relapse after childhood braces, and excellent aligner wear discipline.
- Fixed braces: teens/adults needing complex movements, significant bite correction or poorer aligner compliance.
- Lingual/ceramic: prioritising aesthetics; accept higher cost (lingual) or slightly more friction (ceramic).
Adult vs Teen considerations
- Adults: better for discretion (Invisalign/ceramic/lingual), may need IPR, attachments, elastics; gum health must be stable.
- Teens: compliance varies; fixed braces ensure continuous force. Invisalign Teen includes wear indicators and eruption compensation.
Process & visits
- Consultation & records: exam, photos, digital scan (iTero), X-rays; discuss goals and options.
- Treatment planning: ClinCheck (Invisalign) or bracket bonding plan; consent, quote, finance.
- Active treatment: aligner changes every 7–14 days or braces adjustments every 6–10 weeks.
- Refinements / finishing: minor tweaks near the end are common.
- Retention: retainers nightly long-term; bonded retainers for some cases.
Financing & saving tips
- 0%–low-APR plans: many clinics offer staged payments (credit checks may apply).
- Bundled pricing: choose packages that include refinements, retainers and reviews.
- Choose the right system: for complex bites, fixed braces can be faster/more predictable than chasing refinements with aligners.
- Aftercare costs: budget for replacement retainers (lost/chewed) and long-term reviews.

FAQs
Is Invisalign faster than fixed braces?
For mild cases, Invisalign can be quicker. For complex bite changes or rotations, fixed braces can be more predictable and sometimes faster overall.
Will I need attachments with Invisalign?
Often yes — small tooth-coloured bumps guide specific movements. They’re temporary and removed at the end.
How long must I wear retainers?
Indefinitely at night is the usual advice. Teeth can drift without retention; factor this into lifetime cost.
