Invisalign and teeth straightening
Can you have adult braces if you already have crowns, bridges or missing teeth?
Having crowns, bridges or missing teeth does not automatically rule out adult braces. Your dentist needs to distinguish the teeth that can move safely from fixed restorations and implants that cannot move with them
Talk to us about straightening your teeth
You might have a particular change in mind, or simply want to know what is possible. At a £30 consultation, we can talk through your goals and explain how the next steps are planned.
Please confirm the £30 planned-treatment consultation fee when booking. Scans, additional investigations and emergency assessments may have separate fees.

The short answer: Having crowns, bridges or missing teeth does not automatically rule out adult braces. Your dentist needs to distinguish the teeth that can move safely from fixed restorations and implants that cannot move with them.
You may have considered straightening your teeth for years, only to wonder whether the dental work you have already had makes it too complicated. Perhaps a front tooth has a crown, a back tooth is missing, or you have an older bridge that has served you well. You might even have been told a long time ago that braces were no longer an option.
For many adults, crowns, root-treated teeth and gaps do not automatically prevent orthodontic treatment. They do, however, change what needs to be checked and sometimes how the treatment should be planned. The aim is not simply to make teeth line up in a photograph. It is to move the right teeth, protect existing dental work and finish with a bite you can maintain comfortably.
A good assessment can help separate concerns that matter clinically from ones that only sound complicated.
Does having a crown mean the tooth cannot move?
A crown covers and restores part or all of the visible tooth. It does not, by itself, stop the root and the tooth's supporting structures from responding to appropriate orthodontic forces. In suitable circumstances, teeth with crowns can be moved.
There are practical differences. A bracket may need a different bonding technique on porcelain or metal than it would on enamel. The dentist should also check that the crown is sound, its margins are healthy and the tooth underneath has a reasonable outlook. If the crown is loose, leaking or associated with untreated disease, orthodontics may need to wait until that problem has been addressed.
The position of a crowned tooth matters to the eventual smile design. If it is a different colour or shape from the neighbouring teeth, aligning everything may make that difference more noticeable. It does not mean the crown must automatically be replaced. It means the team should discuss the appearance and bite at the end of treatment, not just at the start.
What if the tooth has had root canal treatment?
A root-treated tooth may sometimes be moved orthodontically, but suitability depends on its condition, root, surrounding bone and any previous problems. The clinician may need appropriate X-rays to understand its history and current health.
If the tooth has a large restoration, previous trauma, a shortened root or signs of ongoing infection, these may change the risk assessment or the treatment objectives. Your orthodontist may recommend coordinating with your usual dentist or a clinician experienced in restoring more heavily treated teeth.
Tell the team about previous injuries or root canal treatment even if the tooth does not hurt. Bringing earlier X-rays or letters, if available, may help. The fact that a tooth looks normal in a smile photograph does not tell the whole story.
Missing teeth can sometimes make braces more useful
A missing tooth creates a space, but it does not necessarily create useful space. Over time, neighbouring teeth can tip towards a gap, opposing teeth may move and the bite may adapt. In some adults, orthodontics can upright tilted teeth, redistribute gaps or create room for a carefully planned replacement.
Imagine that you lost a lower molar several years ago. A tooth behind it may now lean forwards, leaving a gap that is wide near the gum but too narrow in the wrong places — or the reverse. Placing a bridge or implant crown without considering the tooth positions could require compromises in the shape of the replacement.
Orthodontics may help create a more favourable arrangement first. In other cases, the gap can be closed orthodontically, depending on where it is and what movements are feasible. Some gaps are best left alone. The right choice is determined by the bite, the health of the other teeth and what you want to achieve.
Can an implant move with the other teeth?
This is a crucial distinction: an established dental implant does not move like a natural tooth under orthodontic forces. It is anchored directly to bone rather than suspended by the periodontal ligament that allows a natural tooth to move.
If you already have an implant crown, the orthodontist needs to plan tooth movement around its fixed position. Sometimes the existing implant does not complicate the intended change. Sometimes it limits how the space and bite can be adjusted, or makes the original cosmetic goal less realistic.
If you are considering an implant but have not yet had one placed, it may be worth asking whether orthodontics should happen first. Moving neighbouring natural teeth and their roots into better positions can help prepare a site for the eventual replacement. The sequence should be coordinated before the implant is placed, because the implant cannot simply be moved afterwards to correct the spacing.
What if you have a bridge?
A conventional bridge joins replacement teeth to adjacent supporting teeth. Those connected units may restrict individual tooth movements, so an existing bridge needs careful assessment before orthodontic treatment is planned.
Some people can have braces while an established bridge remains in place; others may need the bridge altered or temporarily replaced if the treatment goals require independent movement of its supporting teeth. In certain cases, the limitations of the bridge mean a different orthodontic plan is preferable.
Do not assume a bridge must be removed simply because you want straighter teeth. Ask what movement is required, whether the bridge prevents it and what choices exist. Any decision to change useful existing dentistry should be justified and costed separately.
Should the missing tooth be replaced before or after braces?
Often the answer is after orthodontic movement, especially if an implant is planned and the surrounding teeth need repositioning. But that is not a rule for everyone. The site, available bone, existing restorations and how long the gap has been present all matter.
Your dentist and orthodontic clinician should agree on the desired final space and bite. The planned replacement crown should guide the amount and position of space created, not be squeezed into whatever remains after the teeth are straightened.
If the gap is visible, ask about a temporary aesthetic replacement during treatment. An appliance or provisional tooth may be possible, but it needs to work with the orthodontic plan and be easy to keep clean. Sometimes a temporary solution must change as teeth move.
You should know who will provide the final replacement and whether that fee is part of, or separate from, the orthodontic quotation.
Can you choose Invisalign instead of fixed braces?
Possibly. Clear aligners can be used in many adult cases, including some involving crowns and spaces. But the best appliance depends on the specific movements required, the bite and the position of your existing restorations.
If one or more teeth need significant uprighting, complex root control or carefully coordinated space management, the clinician should explain which appliance is better suited to those objectives. Fixed braces may offer advantages in some situations; aligners may be suitable in others. A hybrid or staged approach is sometimes considered.
Do not choose solely on appearance or the assumption that a removable appliance must be gentler on restored teeth. What matters is an achievable plan with sensible forces and careful monitoring.
Do crowns make braces harder to attach?
Attaching orthodontic brackets or buttons to crowns and other restorative materials can require different surface preparation and bonding systems. The risk of an attachment coming loose may differ from bonding to natural enamel, and removing it at the end requires care to avoid unnecessary damage to the restoration.
Your clinician should assess the material and condition of the crown, and explain any relevant risk. A crown that is already approaching the end of its useful life may be addressed within the broader treatment plan. A good crown that functions well may be kept.
The attachment technique is a practical detail for the treating team, but you are entitled to know if your existing work is at additional risk and how they would manage a problem.
Will braces improve the appearance of my existing crowns?
Braces change tooth position; they do not change the colour, surface texture or original shape of a crown. Once the teeth are better aligned, you may be perfectly happy with the existing restoration. Occasionally a crown that was made to disguise a crooked tooth looks less harmonious when the surrounding teeth have moved.
If you want whitening or bonding afterwards, that should be discussed before treatment begins. Whitening lightens natural enamel, not crowns or existing composite restorations, so matching shades may need additional thought. Small restorative refinements are not inevitable, and they should not be bundled into the plan without explaining their value.
Think of alignment as one part of your smile, rather than a guarantee that every existing restoration will automatically blend in afterwards.
What about gum health and past dental problems?
Healthy supporting tissues are especially important when moving adult teeth. If you have experienced gum disease, tooth mobility, significant recession or loss of bone support, the treating team should assess whether the condition is stable and whether orthodontic movement is appropriate.
Treatment may require coordination with a dentist providing periodontal care. Some people with a history of gum disease can undergo orthodontics successfully when their condition is controlled and carefully monitored; others may be advised against particular movements or against treatment altogether.
Braces also create new cleaning challenges. With fixed appliances, food and plaque collect around brackets and wires. Your ability to clean around crowns, bridgework and gaps needs to be considered from the beginning, not after gums become inflamed.
If you have medical conditions or take medicines that affect oral health, tell the clinician. The assessment should reflect your circumstances rather than relying on the fact that you have seen other adults with similar restorations wearing braces.
What will treatment feel like and how long might it take?
The experience is broadly similar to orthodontics for other adults: appointments to check progress, periods of pressure or tenderness after adjustments, and an ongoing need to maintain the appliances and clean carefully. The exact timetable depends on how far teeth need to move, whether space must be created for a replacement and how your teeth respond.
You may find that a seemingly small cosmetic change requires more planning because of your bite or existing dental work. Equally, a missing back tooth does not automatically turn a straightforward front-tooth alignment into a full-mouth rehabilitation programme.
Ask which stages are necessary, which are optional and what could alter the expected duration. It is better to understand an honest range than to rely on a precise finish date given before records have been examined.
How should the quotation be organised?
A useful written plan separates orthodontic fees from other possible dentistry. Ask whether it includes the chosen appliance, records, adjustments, repairs, retainers and follow-up. If bridgework, crowns, implants, periodontal treatment or a temporary replacement might be involved, those should be identified as separate elements or clearly described as included.
Sometimes the most sensible plan is to straighten teeth now and consider cosmetic refinements later. You should know whether you can make that decision in stages, rather than feeling obliged to agree to a complete smile makeover before seeing how alignment improves your teeth.
Future maintenance matters too. Retainers will be needed to help preserve the new positions, and existing crowns or implant restorations continue to require routine dental care.
A first consultation built around the dentistry you already have
Bring a list of your concerns and, if you have them, previous dental plans or information about implants, crowns or bridges. Say clearly what you want to keep. Perhaps your front crown looks natural and you would prefer not to change it. Perhaps the missing tooth is the reason you are considering straightening in the first place.
Iconic Smiles advertises a £30 planned-treatment consultation, providing an initial opportunity to discuss treatment options. Confirm which clinician or specialist assessment is appropriate, the fee for that appointment and any additional records before booking.
The most valuable outcome is a coordinated plan that respects sound existing dentistry. Adult braces should improve what can be improved safely, not trigger a chain of replacements simply because you have had dental work in the past.
Questions patients often ask
Can braces move a crowned tooth? They often can, provided the underlying tooth and its support are healthy enough. The crown may require a different bracket bonding method.
Can braces move a dental implant? No. Established implants do not move orthodontically like natural teeth, so planning must account for their position.
Do I need to replace a bridge before braces? Not always. It depends on whether the teeth joined by the bridge need to move independently.
Can orthodontics close a gap where a tooth is missing? Sometimes. In other cases, the treatment aims to create appropriate space for an implant, bridge or another replacement.
Is Invisalign suitable for people with several crowns? It may be, but suitability depends on the planned movements, materials, bite and overall dental health.
