Can adults get orthodontic treatment?
Yes. There is no upper age limit for orthodontic treatment. Adults of all ages — including those in their 40s, 50s, 60s, and beyond — routinely undergo braces and clear aligner treatment in the UK.
The most significant difference from teenage treatment is biological: adult bone is denser and more fully remodelled, which can slow tooth movement slightly and may affect the predictability of certain movements. Treatment typically takes a little longer for adults than for teenagers with equivalent case complexity. However, adults are often better at following instructions — consistent retainer wear, aligner compliance, and dietary restrictions — which can offset this difference.
Adults seek treatment for many reasons: crowding that was never treated in childhood, gaps that have widened over time, relapse after earlier braces when a retainer was not worn, bite problems affecting chewing or jaw comfort, or simply wanting a straighter smile. What matters more than age is the health of your teeth, gums and supporting bone.
The demand for adult orthodontics has grown significantly. The British Orthodontic Society has noted a long-term trend toward more adults seeking treatment, and clear aligner systems have made orthodontic treatment more accessible and discreet for working adults.
NHS orthodontics for adults
NHS orthodontic treatment in England is primarily available to patients under 18 who meet the clinical need threshold (IOTN DHC grade 3.6 or above). Adults do not ordinarily qualify for NHS orthodontic treatment for cosmetic or functional reasons.
The main exceptions for adults include:
Orthognathic (jaw) surgery cases — where pre- and post-surgical orthodontics is needed as part of a surgical treatment plan for significant jaw discrepancy
Cleft palate and craniofacial conditions — managed through specialist NHS services
Restorative pre-treatment — where orthodontic tooth movement is required to facilitate restorative dental work such as implants or bridges
Adults seeking orthodontic treatment outside these categories will need private treatment.
Treatment options for adults
All major orthodontic treatment types are available to adults. The right choice depends on the complexity of your case, your aesthetic preferences, your lifestyle, and your budget.
| Treatment | Visibility | Typical UK cost | Case suitability |
|---|---|---|---|
| Metal braces | Visible | £1,500–£3,500 | All complexities; most affordable |
| Ceramic braces | Discreet | £2,000–£4,500 | Most cases; popular with adults |
| Lingual braces | Hidden (behind teeth) | £4,000–£8,000 | Most cases; highest cost; requires specialist |
| Clear aligners | Near invisible | £1,500–£5,500 | Mild–moderate; removable; compliance required |
| Invisalign | Near invisible | £2,500–£5,500 | Mild–complex; most evidence base of aligner systems |
What's different about adult treatment?
Several factors make adult orthodontics clinically different from teenage treatment:
No growth remaining. Orthodontic correction in adults is purely dental — jaw growth cannot be influenced. Significant skeletal discrepancies (such as a large underbite or severe open bite) may require surgical input in adults rather than growth modification.
Gum and bone health. Adults are more likely to have existing dental restorations (crowns, bridges, implants), gum recession, or a history of gum disease. All of these must be stable before orthodontic treatment begins. Active gum disease is a contraindication to orthodontic treatment.
Bone density. Denser adult bone can mean slightly slower tooth movement and may reduce the predictability of some movements. This can add time compared to equivalent teenage cases.
Wisdom teeth. If wisdom teeth are present and impacted, they may need to be assessed as part of the treatment plan.
Relapse tendency. Adults who had braces as teenagers and didn't maintain retainer wear often experience relapse. Re-treatment in adults requires understanding the original treatment and current bone state.
Gum health and bone checks before adult braces
Adults are more likely than teenagers to have gum disease, bone loss around teeth or a history of periodontal treatment. Before braces or aligners start, a clinician should carry out a Basic Periodontal Examination (BPE) to check for bleeding, pocketing and bone loss. Moving teeth through bone already weakened by active gum disease can speed up attachment loss.
Advanced periodontitis (stage III or IV) needs to be treated and stable before orthodontics begins. Stable means no active infection, no progressing bone loss and gum pockets within acceptable limits over more than one review. Patients with a gum disease history are often co-managed with a periodontist. Well-maintained patients who have had gum treatment in the past can usually go ahead safely.
How long does adult orthodontic treatment take?
Duration varies with case complexity. Typical ranges for adults:
Mild cases (minor crowding or spacing): 6–12 months
Moderate cases (overbite, rotations, moderate crowding): 12–24 months
Complex cases (extractions, significant bite issues): 18–36 months
Surgical cases (orthognathic jaw surgery): 24–48+ months including pre- and post-surgical phases
How much does adult orthodontic treatment cost in the UK?
Adult orthodontic treatment in the UK is entirely private in most cases. The cost varies by treatment type, case complexity, and practice location. London and the South East are generally 20–40% more expensive than other regions.
Most private practices offer 0% interest payment plans spread over 12–24 months. A deposit is usually required at the start of treatment. Ask specifically whether the fee includes retainers and any refinement trays (for aligners) before committing.
Are braces or clear aligners better for adults?
Neither is universally better — the right choice depends on your case. Fixed braces (metal or ceramic) give the orthodontist more precise control, particularly for complex bite corrections, rotations, and vertical movements. They work 24 hours a day with no compliance requirement.
Clear aligners are popular with adults because they are nearly invisible and removable. They require strict 20–22 hours per day wear to be effective. For mild to moderate cases in motivated adults, they can be as effective as braces. For complex cases, fixed braces remain the standard recommendation.
Many adults opt for ceramic braces as a middle ground — fixed, precise, but far less visible than metal brackets.
Finding an orthodontist for adult treatment
Verify that your treating clinician is registered with the GDC (General Dental Council). For the best outcomes in adult cases — particularly those involving bite correction, restorative co-ordination, or complex tooth movements — seek a GDC-registered specialist orthodontist. Specialist orthodontists have completed at least three years of full-time postgraduate training in orthodontics beyond their dental degree and appear on the GDC specialist register.
How to compare adult braces quotes
Two quotes with similar headline prices can cover very different things. Ask for a written, itemised breakdown and check whether it includes:
Records — digital scans, photographs and X-rays
All review appointments — adjustments for braces or check-ins for aligners
Refinements — extra aligner stages or wire changes if treatment runs longer than planned
Retainers — which type, and whether replacements are covered
Emergency visits — broken brackets, poking wires or lost aligners
Useful questions at consultation: what happens if treatment takes longer than planned, are retainers included and of what type, and who you will see at each appointment. A second opinion before signing is reasonable for any significant treatment fee.
A photo-based pre-assessment is a useful way to get an initial indication of suitability and cost range before committing to a consultation fee at a practice.
