There is no age at which teeth stop moving. The biology that lets an orthodontist move a fourteen-year-old’s teeth works just as well at forty or sixty, provided the gum and bone holding them are healthy. Adults make up a large and growing proportion of orthodontic patients, and the treatment is routine.
What differs is not whether it works, but the context it happens in. Adults arrive with gum histories, fillings, crowns, missing teeth, worn edges and habits, and all of those shape the plan.
What is genuinely different about treating adults
Gum health comes first, without exception
This is the most important difference. Moving teeth through tissue that is actively inflamed accelerates bone loss rather than causing it, and the damage is not reversible. Any gum disease must be treated and stabilised, and the response confirmed, before appliances go on. Treatment then continues alongside periodontal maintenance. Our gum and periodontal care page covers that stage, and where bone support is already reduced, the plan is adjusted — lighter forces, and more modest goals.
No growth to work with
In a growing child, some corrections use jaw growth to do part of the work. In an adult that option has gone. Skeletal discrepancies that could have been modified in childhood can, in adulthood, only be camouflaged by moving teeth, or corrected surgically in combination with orthodontics. This is why the honest answer for some adult cases is that the teeth can be straightened but the underlying jaw relationship cannot.
Movement is a little slower
Bone remodels more readily during growth. The difference is real but modest, and it is not a reason to avoid treatment.
Existing dental work
Brackets bond differently to porcelain and metal than to enamel, and this is manageable but has to be planned. Crowns, bridges, veneers and implants all matter: an implant does not move at all, so it acts as a fixed point in the arch, and any orthodontics should ideally happen before implants are placed rather than after.
Teeth that have drifted after losses
Where teeth have been missing for years, the neighbours have tipped in and the opposing tooth has over-erupted. Uprighting them often makes a far better restorative result possible — sometimes orthodontics is the preparation for the real treatment rather than the treatment itself. See replacing several missing teeth.
Worn teeth and clenching
Many adults present with wear from grinding. Correcting the bite can address the cause; a night guard usually forms part of the plan, and restoring worn edges is sequenced after the teeth are in position, not before — see teeth grinding and jaw clenching.
Why adults come for treatment
Some reasons are functional: crowding that cannot be cleaned and keeps causing decay and gum inflammation; a bite causing wear; teeth drifting after a loss; preparation for restorative work. Some are cosmetic, including relapse after treatment in adolescence when retainers were abandoned — which is extremely common and nothing to be embarrassed about.
Both are valid. You do not need a clinical justification to want your teeth straight.
Appliance options
Adults commonly want discretion. Ceramic brackets are much less conspicuous than metal; lingual braces are invisible from the front; clear aligners are removable and barely visible. Which is appropriate depends on the movements required, not on preference alone — our comparison of braces and clear aligners explains where each is stronger.
One practical note on aligners for adults: they suit a working adult’s life in many ways, but they demand 20 to 22 hours of wear a day. Meetings, meals out and forgetfulness are exactly what erodes that.
Risks worth knowing as an adult
- Gum recession is more likely where gum is already thin or bone support reduced, particularly with certain movements.
- Root shortening occurs to a small degree in many patients and is usually of no consequence; it is monitored radiographically.
- Black triangles — small gaps at the gum between teeth — can appear when crowded teeth are aligned and the gum does not fill the new space. This is more common in adults and should be discussed before treatment, not discovered afterwards.
- Relapse without retention, which applies at every age. See retainers.
Fitting treatment around adult life
The practical objections adults raise are usually about work and appearance rather than clinical concerns, and most of them have answers worth knowing before deciding.
Appointments during working hours. Fixed braces need adjusting every four to eight weeks for the duration, plus occasional unscheduled visits for a debonded bracket. Aligner treatment generally needs fewer and shorter visits, with trays issued in batches — which for many working adults is the deciding practical factor rather than appearance.
Speaking at work. Conventional braces affect speech barely and briefly. Lingual braces, fitted behind the teeth, affect it noticeably for a few weeks — worth knowing if you present or teach for a living. Aligners cause a slight lisp for the first week or so.
Eating out. With fixed braces, hard and sticky foods are restricted throughout. With aligners there are no restrictions, but you have to remove them, and you must brush before putting them back — which is the thing that erodes wear time in a working week more than anything else.
Events with a date on them. Tell the orthodontist at the planning stage. Appliances can sometimes be sequenced around a specific date, and knowing in advance is far more useful than asking two months beforehand.
When orthodontics is preparation rather than the treatment
A significant proportion of adult orthodontics is not done for appearance at all. It is done to make something else possible:
- Uprighting a tipped molar so there is room for a crown or an implant of normal shape where a tooth has been missing for years.
- Opening or closing a space so a replacement tooth is the right width rather than too wide or too narrow.
- Intruding an over-erupted tooth that has dropped into the gap opposite a missing tooth and left no room to restore it.
- Redistributing the bite so that restorative work is not overloaded and does not keep failing.
- Moving a tooth back into the bone where it sits prominently and the gum keeps receding.
In these cases the orthodontic phase is often limited and shorter than full treatment, and it is planned jointly with whoever is doing the restorative work. If you have been told a gap cannot be restored properly, it is worth asking whether a short course of orthodontics would change that.
Frequently asked questions
Am I too old?
No. Health of the supporting tissue is what matters, not age.
How long will it take?
Comparable to treatment at any age, commonly one to two years — see how long orthodontic treatment takes.
Can I have treatment if I have crowns or implants?
Yes, with planning. Implants are fixed points and change the mechanics.
Can I have treatment if I have lost bone from gum disease?
Often yes, once the condition is stable, with lighter forces and realistic goals. It needs honest discussion of what is achievable.
Will whitening or veneers be needed too?
Not necessarily. Where they are wanted, they come after orthodontics, not before — see smile design.

An adult assessment looks at the gums and existing dental work as much as at the alignment. See our orthodontics page, or book an appointment.
