Do wisdom teeth need to be removed before braces?
Usually not. Most people can start braces or Invisalign with their wisdom teeth in place. Removal is advised when a wisdom tooth is causing problems, blocks a planned tooth movement, or is likely to become stuck against the second molar. Research has not shown that wisdom teeth push straightened teeth crooked; wearing retainers matters far more. At Creative Arts in Dubai, our specialist orthodontists check the wisdom teeth on X-rays at the orthodontic assessment.

Why do people think wisdom teeth crowd the front teeth?
The idea is understandable. Wisdom teeth usually appear between the late teens and mid-twenties, and that is also when many people notice their lower front teeth becoming slightly more crowded, sometimes years after braces came off. It seems logical that the new teeth at the back are pushing the others forward.
The research does not support that explanation. Lower front teeth tend to become a little more crowded with age in many people, including those who never had wisdom teeth, because of continuing jaw growth, the forces of chewing and the natural tendency of teeth to drift forward over a lifetime. A 2014 systematic review in The Scientific World Journal concluded that definitive conclusions on the role of wisdom teeth in crowding cannot be drawn, that most studies show no causal link, and that removing wisdom teeth to prevent crowding or relapse after orthodontic treatment is not justified. A 2023 systematic review in Dentistry Journal likewise found no proven connection between lower wisdom teeth and the return of lower front crowding after treatment.
In other words, crowding that comes back after braces is mainly a retention question, not a wisdom tooth question.
When might an orthodontist recommend removing wisdom teeth?
Removal is decided tooth by tooth, for a specific reason. These are the situations in which it is usually discussed.
| Timing | When removal may be advised | Notes |
|---|---|---|
| Before treatment | The wisdom tooth is already causing gum infection, decay or damage to the second molar | The same reasons that apply to anyone, braces or not |
| Before treatment | The plan moves the back teeth backwards and the wisdom tooth is in the way | Common when space is created by moving molars rather than removing other teeth |
| During treatment | A wisdom tooth erupting behind the braces or aligners starts to cause problems | Treatment can usually continue around the extraction |
| After treatment | X-rays show the tooth will not have room and is tilting against the second molar | Planned for its own sake, not to protect the result |
| Rarely | A wisdom tooth is moved forward to replace a missing or lost molar | Possible in some cases; your orthodontist will explain whether it suits yours |
| Usually not | Healthy wisdom teeth with no effect on the planned movement | They can stay and be monitored |
Extractions planned to create space for straightening usually involve other teeth, often premolars; see extractions for braces.
What does the orthodontic assessment check about wisdom teeth?
Wisdom teeth are part of every orthodontic assessment, even though they are rarely the focus. On the panoramic X-ray the orthodontist looks at:
- Whether they are present and how far they have developed; some people have fewer than four.
- Their angle and space: whether there is room behind the second molars or whether a lower wisdom tooth is already tilting against the tooth in front.
- Their effect on the plan: if the back teeth need to move backwards, the wisdom teeth may decide how much movement is possible.
- Any disease, such as decay in the wisdom tooth or the second molar, or changes in the bone around them, which would need attention regardless of orthodontics.
The answer for most people is that the wisdom teeth can be left alone and monitored. A 2020 Cochrane review of removing versus keeping symptom-free impacted wisdom teeth found that the included studies showed no clinically significant effect of removal on crowding, and advised regular monitoring of teeth that are kept.
Do wisdom teeth matter more with Invisalign than with braces?
The biology is the same, but there are a few practical differences with clear aligners. Aligners are made from a digital scan of the teeth that are present at the time. If a wisdom tooth has already erupted, it may simply be included in the aligner; if it is still under the gum, the aligner usually stops at the second molar.
A wisdom tooth that comes through partway during treatment can stop the back of an aligner fitting properly, or make the gum sore under the edge. This is usually managed by trimming the aligner or by a new scan. When the plan includes moving the molars backwards to create space, which aligners can do in some cases, the orthodontist checks on the X-rays whether the wisdom teeth leave room for that movement before treatment starts.
The Invisalign treatment page explains how aligner cases are planned, and our Invisalign vs braces guide covers which appliance suits which problem.
Will removing wisdom teeth after braces stop teeth moving back?
No. Teeth tend to drift after braces or aligners whether or not wisdom teeth are present, and removing them does not replace the job a retainer does. The fibres around the teeth and the soft tissues keep exerting gentle pressure long after treatment ends, which is why retention is long-term.
At the end of treatment you will usually be given a bonded wire behind the front teeth, a removable retainer, or both. Wearing them as instructed is what protects the result. Our retainers page explains the types, and the guide to how long to wear a retainer covers the schedule.
If your teeth have moved since treatment, the cause is worth investigating rather than assuming it is the wisdom teeth: a broken bonded wire, a retainer that has not been worn, or changes in the gums are all more common explanations.
Do not have healthy wisdom teeth removed just to protect your braces result
Removing wisdom teeth is surgery, with recovery time and its own small risks. If a wisdom tooth is healthy and does not affect your orthodontic plan, the evidence does not support removing it to prevent crowding. If it causes problems in the future, it can be removed then, for that reason.
What happens to wisdom teeth during teenage orthodontic treatment?
In teenagers, wisdom teeth are usually still developing when braces or aligners start. They show up on the panoramic X-ray taken at the orthodontic assessment, often as tooth buds without roots. At that age it is rarely possible to tell whether they will erupt normally, so the usual approach is to note them and check them again on later X-rays.
Towards the end of treatment, or a few years afterwards, the orthodontist or general dentist can usually see whether there is enough space. If it looks as though a lower wisdom tooth will become impacted against the second molar, removal can be planned at that stage on its own merits. Our teen orthodontics page covers treatment at this age.

Orthodontics at Creative ArtsWho decides, and who removes the tooth?
At Creative Arts, orthodontic treatment is planned by our specialist orthodontists, Dr. Muhannad Kazzaz and Dr. Valeriia Kozachenko. At the assessment they examine the bite, take the X-rays needed and explain whether your wisdom teeth play any part in the plan. If removal is advised, they explain why and when, and the extraction is carried out by the clinic's oral surgery team; the wisdom tooth removal page explains that part.
If you are not having orthodontic treatment and simply want to know whether your wisdom teeth should come out, our guide do wisdom teeth need removing? covers the general reasons for removing or keeping them.
