# Wisdom Teeth, Braces and Orthodontic Treatment — What You Need to Know

Wisdom teeth are often blamed for crowding and orthodontic relapse. But the evidence tells a different story. Here is what the research actually shows — and when removal is genuinely warranted.

## Do wisdom teeth cause crowding?

The belief that wisdom teeth push teeth forward and cause crowding is widespread but not well supported by evidence. Research shows late lower incisor crowding occurs at similar rates whether wisdom teeth are present, absent, or impacted. It is caused primarily by late jaw growth and natural ageing of the dentition, not wisdom tooth pressure. The British Dental Association and NHS no longer recommend routine prophylactic removal of asymptomatic wisdom teeth.

## When wisdom teeth do matter

Not all wisdom teeth can be ignored. Partially erupted wisdom teeth can cause pericoronitis — a painful infection of the surrounding gum — and recurrent pericoronitis is a reason for extraction in its own right. An impacted wisdom tooth that is resorbing the root of the adjacent second molar is rare but needs early action. Impacted wisdom teeth lying in the path of tooth movement may need to be removed before or during orthodontic treatment, particularly where upper molars are being moved backwards to correct a Class II bite or to create space without extracting front teeth. Fully impacted, asymptomatic wisdom teeth are typically monitored rather than removed. Where space is being opened near a wisdom tooth for a future implant, extraction may be needed to avoid complications. Your orthodontist will review an OPG (panoramic) X-ray and advise based on your specific anatomy.

## Before braces — is removal needed?

Not automatically. Your orthodontist will review your X-rays at the treatment planning stage and assess whether wisdom teeth interfere with the planned tooth movement. In many cases, wisdom teeth are simply monitored throughout treatment. Extraction is only recommended where there is a specific clinical reason — impaction in the path of movement, infection risk from a partially erupted tooth, or space requirements for a future implant. Removing healthy, asymptomatic wisdom teeth solely on the assumption they will cause crowding is not evidence-based.

## After braces — do wisdom teeth cause relapse?

No strong evidence supports wisdom teeth as a primary driver of post-treatment relapse. Studies following patients for many years after orthodontic treatment show similar relapse rates regardless of whether wisdom teeth were present, removed, or impacted. The primary cause of relapse is not wearing retainers as prescribed. The British Orthodontic Society advises that retainers should be worn indefinitely, and consistent retainer use is the only evidence-based way to maintain results. If your teeth have moved after braces, the most likely explanation is inadequate retainer wear.

## During treatment

It is common for wisdom teeth to begin erupting during orthodontic treatment, particularly in teenagers and young adults. In most cases this causes no problem and treatment continues as planned. Your orthodontist monitors progress via periodic X-rays. Extraction may be considered if an erupting wisdom tooth begins affecting the position of the adjacent second molar or disrupts the treatment plan — but this is assessed case by case rather than as a precaution. If you develop pain, swelling, a bad taste or difficulty opening your mouth, that may be pericoronitis — see a dentist promptly rather than waiting for your next orthodontic review.

## Wisdom teeth and clear aligners

Unerupted wisdom teeth are rarely a problem for clear aligner treatment, because the trays only cover erupted teeth. A wisdom tooth that starts erupting during a long aligner course can cause discomfort and may stop the back of the final trays fitting properly, so if eruption is expected your orthodontist may suggest extraction before treatment starts. A partly erupted wisdom tooth also makes it harder to clean around the second molar, which matters for any orthodontic patient.

## NHS vs private wisdom tooth extraction

Wisdom tooth removal is available on the NHS where there is a clinical reason, such as recurrent pericoronitis, decay or gum disease that cannot be treated, or damage to the neighbouring tooth. Following NICE guidance, healthy wisdom teeth that cause no symptoms are not removed as a precaution on the NHS in England. A straightforward NHS extraction falls under the Band 2 charge of £76.60; more complex surgical cases may be referred to a hospital oral surgery department. Privately, expect roughly £150 to £400 per tooth for a routine extraction and £300 to £600 or more for a surgical impaction.

### Frequently Asked Questions

Will I need wisdom teeth removed before braces?

Not necessarily. Your orthodontist will review your X-rays and advise based on your specific anatomy. Removal is only recommended where there is a clinical reason — such as impaction in the path of tooth movement, infection risk, or implant planning. Removal as a routine precaution is not supported by evidence.

Do wisdom teeth cause crowding after braces?

Research does not support this. Late lower incisor crowding occurs at similar rates whether wisdom teeth are present or absent. Retainer wear — or lack of it — is the primary determinant of whether teeth stay straight after orthodontic treatment.

Why does my orthodontist say wisdom teeth need removing?

If your orthodontist recommends extraction, there will be a specific clinical reason — impaction in the path of movement, infection risk from a partially erupted tooth, or space requirements for a future implant. Ask them to explain exactly why removal is needed in your case.

At what age do wisdom teeth come through?

Wisdom teeth typically erupt between the ages of 17 and 25. They are the third molars — the last teeth to arrive — which is why they so often come through after orthodontic treatment has already finished. Timing varies a great deal between individuals: some people see them at 16, others not until their late twenties. A significant number never have them erupt fully at all, with the tooth staying partly or completely buried in the jaw, which is what impaction means, and some people never develop them in the first place, which is a normal anatomical variation. Because eruption is so unpredictable, orthodontists monitor wisdom teeth on X-rays rather than working to a fixed timetable.

Can I get a quote with wisdom teeth not yet through?

Yes. A photo-based assessment from Virtual Consultant Online works from the teeth that are currently visible, so unerupted wisdom teeth do not stop you getting an indicative view of your treatment options and likely cost. For the great majority of cases they are not relevant to the plan anyway: wisdom teeth sit at the very back of the arch and rarely affect how the front teeth are aligned. What a photo cannot show is whether they are impacted or lying in the path of planned movement, which needs an X-ray. If they turn out to matter, your orthodontist will pick that up at the in-person consultation and factor it into the formal plan.

What happens if a wisdom tooth erupts during my treatment?

It is common for wisdom teeth to start coming through while braces are still active, particularly in teenagers and young adults. In most cases treatment continues as planned, with your orthodontist monitoring progress on periodic X-rays. Extraction is only considered if the erupting tooth begins affecting the position of the adjacent second molar or disrupts the treatment plan.

Can wisdom teeth affect my retainer?

A wisdom tooth that erupts after your retainer was made will not be covered by a removable retainer, but the retainer still protects every tooth it does cover, so keep wearing it as prescribed. If the new tooth stops the retainer seating fully, or it starts to feel tight at the back, tell your orthodontist or dentist; they may adjust or remake it. Do not stop wearing a retainer because a wisdom tooth is coming through. Consistent retainer wear, not wisdom tooth removal, is what keeps teeth straight after braces.

Are wisdom tooth extractions available on the NHS?

Yes, where there is a clinical need, such as repeated infection around a partly erupted tooth, decay or gum disease that cannot be treated, or damage to the neighbouring molar. Removing healthy wisdom teeth that cause no problems is not routinely done on the NHS in England, in line with NICE guidance. Most NHS extractions carry the Band 2 charge of £76.60, and complex surgical cases may be referred to a hospital oral surgery department. Removal simply to protect an orthodontic result is not a clinical indication, because the evidence does not show it prevents crowding.
