What can Invisalign fix?
Invisalign can fix crowding, gaps between teeth, teeth that have moved back after braces and many bite problems, including overbite, overjet, crossbite and some open bites, often helped by attachments, elastics or small amounts of enamel polishing. It is less suited to large rotations of rounded teeth, major vertical movements and jaw-size differences that may need surgery. At Creative Arts in Dubai, a specialist orthodontist decides after examining your teeth, bite, gums and X-rays.

Teeth problem or jaw problem: why does it matter?
Most questions about what aligners can do come down to one distinction. A dental problem sits in the teeth: they are crowded, spaced, tipped or rotated, while the jaws themselves are in a reasonable relationship. A skeletal problem sits in the bones: one jaw is noticeably longer, shorter, wider or narrower than the other. Aligners move teeth. They do not change the size of an adult jaw.
Many bite problems are a mix of the two. A mild skeletal difference can often be disguised by moving the teeth, a strategy called camouflage. A larger one may need orthodontic treatment combined with jaw surgery in adults, or growth-related treatment planned in younger patients. Telling these apart takes a clinical examination and usually X-rays, which is why a photo or an online questionnaire cannot answer whether Invisalign will work for you.
Age changes the picture too. In a growing teenager, some jaw differences can still be influenced while growth continues; in an adult, the jaws are set, so the same problem is treated either by moving teeth within the bone or, if the difference is large, with surgery.
Which problems can Invisalign treat?
A general guide. Each row depends on how severe the problem is and on your gums, roots and bite.
| Problem | Can aligners treat it? | What usually helps or limits it |
|---|---|---|
| Mild to moderate crowding | Usually yes | Space from small amounts of enamel polishing (IPR), arch shaping or tooth movement planned in the simulation |
| Gaps between teeth | Usually yes | Small spaces close well; a large gap left by a missing tooth may need a restorative plan as well |
| Relapse after earlier braces | Often yes | Usually a shorter course, followed by long-term retainers |
| Overjet (protruding upper front teeth) | Often, when mainly dental | Space to pull teeth back, elastics; a large jaw difference may need another approach |
| Deep overbite | Often | Attachments and planned vertical movements; very deep bites can take longer |
| Crossbite | Often, when dental | Single-tooth crossbites respond well; narrow upper jaws in adults are more limited |
| Open bite | Some cases | Depends on cause; habits such as tongue thrust must be addressed for the result to hold |
| Underbite | Mild dental cases | Clear jaw-size differences in adults usually need combined orthodontic and surgical care |
| Severe crowding | Sometimes | May need extractions; many such cases are more predictable with fixed braces |
| Impacted teeth | Rarely on their own | Usually need surgical exposure and fixed appliances |
Severity matters as much as the type of problem. Two people with the same label can need very different plans.
Why do bite problems need more planning with aligners?
Straightening teeth that are crowded or spaced mostly involves tipping and turning them within the arch. Correcting a bite asks for more: teeth may need to move up or down, whole groups of teeth may need to shift forwards or backwards, and the upper and lower arches have to be coordinated so they meet evenly when you close. That is where attachments, elastics and staged movements come in, and where treatment usually takes longer.
- Deep bite and overjet. Correction usually combines levelling the front teeth with moving them back into space; our page on overbite correction explains the options.
- Crossbite. A single tooth caught behind its neighbour is often simple; a narrow upper arch is a different problem, covered under crossbite correction.
- Open bite. The cause has to be found first, because a habit or a skeletal pattern changes both the plan and how stable the result is. See open bite correction.
- Underbite. The key question is how much of it comes from the jaw. Our page on underbite correction explains why X-rays decide.
What helps aligners do more than straighten teeth?
A smooth plastic tray has limited grip on a tooth. Several additions extend what it can do:
- Attachments. Small tooth-coloured bumps bonded to selected teeth give the aligner something to push against, which is what makes rotations, root movement and moving teeth up or down possible. They are polished off at the end.
- Elastics. Small rubber bands hooked between upper and lower aligners shift the bite forwards or backwards, much as they do with braces.
- IPR. Polishing a few tenths of a millimetre of enamel between selected teeth creates room for alignment and can avoid an extraction in mild to moderate crowding.
- Other auxiliaries. In selected cases an orthodontist may add a temporary anchorage device or an expander, or use a short phase of fixed appliances for one difficult movement.
Each of these is planned before the aligners are made, so you can see in the simulation and written plan exactly what your case involves.
When are braces or another approach a better choice?
Some movements remain harder with aligners. Large rotations of rounded teeth such as lower premolars and canines, major vertical movements, and moving roots bodily over long distances are generally more predictable with fixed braces. Several of these together in one case often tip the balance. A 2019 systematic review in BMC Oral Health found that fixed braces performed better than aligners for bite contacts, torque control and retention, while aligners shortened treatment time in the studies it included.
Other situations call for something first or instead:
- Active gum disease must be treated and stabilised before any tooth is moved.
- Short roots or previous root resorption change how forces and duration are planned.
- A significant jaw-size difference in an adult may need orthodontics combined with surgery; our page on surgical orthodontics explains when.
- Crowns, veneers or implants on or near the teeth to be moved need extra planning; our guide to Invisalign with crowns and implants covers this.
- Doubts about wear. Aligners only work for 20 to 22 hours a day. Braces that are always in place can be the better tool for someone who knows they will struggle.
At Creative Arts both aligners and fixed braces are provided, so the appliance follows the diagnosis.
Not sure whether your case suits aligners? Our specialist orthodontists assess teeth, bite, gums and X-rays where indicated, then tell you honestly whether Invisalign, braces or another approach fits.
Invisalign at Creative ArtsHow does a specialist orthodontist decide if Invisalign suits you?
At Creative Arts, aligner cases are assessed and planned by our specialist orthodontists, Dr. Muhannad Kazzaz and Dr. Valeriia Kozachenko. The assessment covers more than the visible alignment:
- How the upper and lower teeth meet, front to back, side to side and vertically.
- Whether the problem is dental, skeletal or both, using X-rays where indicated.
- Gum health, bone levels and the length and shape of the roots.
- Existing crowns, veneers, implants and missing teeth.
- Jaw joint comfort and function, with a TMJ assessment where symptoms suggest it.
- Habits and how consistently you can wear a removable appliance.
An intraoral 3D scan is then used to simulate the movements. If the simulation shows that aligners would need unrealistic movements, or that braces would give a better result, you are told before anything is ordered. Our guide to how long Invisalign takes explains how the case type affects the timeline.
Aligners fix position, not colour or shape
Invisalign moves teeth; it does not change their colour, size or shape. Worn edges, chips, staining and small teeth may need whitening, bonding or other restorative work once the teeth are aligned. Aligning first often means less tooth needs to be altered afterwards.
