Gwangjin-gu Dental Clinic: Do I Really Need to Remove My Wisdom Teeth Before Orthodontic Treatment?

Hello, this is S Leader Dental Hospital, a Gwangjin-gu dental clinic.

If you are considering orthodontic treatment, you may have heard this at least once.

“Please remove your wisdom teeth before starting orthodontic treatment.” But if the wisdom tooth does not hurt right now and does not interfere with daily life, you may wonder, “Is it really necessary to extract it before orthodontic treatment?”

Many people also ask, “Can’t I just leave it in?”

In fact, wisdom teeth can become an important factor in the pre-orthodontic stage depending on their “eruption position,” “direction,” and the “relationship between the teeth and jawbone.” In some cases, it is actually better not to touch them.

In other words, removing them unconditionally is not always the best choice, but there are definitely situations where you may regret it if they are not removed.

So in what cases should wisdom teeth be removed before orthodontic treatment?

And is the reason simply to “make room”?

✅ Why should wisdom teeth be considered before orthodontic treatment?

Wisdom teeth usually begin to erupt in the late teens to early twenties, around the same time that most orthodontic treatment starts.

The problem is that wisdom teeth at this age often do not erupt properly or do not grow straight.

In particular, lower wisdom teeth often grow sideways or remain impacted and hidden in the gum due to the structure of the jawbone,

and if the wisdom tooth exerts even a slight forward pushing force in this state, the front teeth may gradually move, interfering with the results of orthodontic treatment or increasing the possibility of relapse.

Whether wisdom teeth actually push corrected teeth out of place is still a debated topic, but clinically it has also been clearly reported that orthodontic stability often improves after wisdom tooth extraction.

In cases where the teeth become neatly aligned but gaps reopen between the front teeth or rotated teeth move back again, pressure from wisdom teeth or lack of space is often the cause.

✅ What benefits can wisdom tooth extraction provide?

1. Securing space for tooth movement

Orthodontic treatment is not simply about lining up the teeth neatly; it is the process of arranging them in their correct positions while also adjusting the overall bite relationship.

At this time, securing space is the most important factor.

If wisdom teeth take up space in the back, it becomes more difficult to move the molars backward, and it can be challenging when the entire dental arch needs to be adjusted more broadly.

Especially in cases where teeth are extracted as part of orthodontic treatment, if wisdom teeth remain, the range of bone movement becomes narrower, which can affect the overall treatment plan.

In such cases, since it makes treatment planning itself more difficult, it is advantageous to remove the wisdom teeth first, secure space, and improve the accuracy and stability of orthodontic treatment.

2. A choice to prevent relapse after orthodontic treatment

When wisdom teeth are impacted or partially erupted, even if there is no pain, they can exert a “slight force” that pushes the entire dentition forward.

This small force can affect the teeth after orthodontic treatment and lead to spaces opening between the front teeth or the dental alignment gradually breaking down.

This is especially more likely to happen when wearing a retainer is skipped or stopped around the time the wisdom teeth erupt.

In other words, the wisdom tooth does not directly create the problem, but acts as a “disturbing factor” that disrupts the well-aligned dentition created by orthodontics.

To prevent this relapse, removing wisdom teeth in advance can be an “investment for maintaining orthodontic results for a long time.”

✅ Some wisdom teeth must be removed before orthodontic treatment.

If any of the following apply, wisdom tooth extraction before orthodontic treatment should be strongly considered.

• The lower wisdom tooth is impacted and lying sideways

• The upper wisdom tooth has partially erupted and carries a risk of inflammation

• The orthodontic plan includes moving the entire dental arch backward

• Cases with a high possibility of relapse of the front teeth after orthodontic treatment (such as protrusion)

• The wisdom tooth is pushing the molars, and the molar position needs to be corrected

On the other hand, in the following cases, extraction may be postponed or decided after observing the condition once orthodontic treatment is completed.

• The wisdom tooth has fully erupted straight and is functioning properly in a centered position

• Both upper and lower wisdom teeth are well aligned and contributing to chewing function

• The patient is older and the wisdom tooth is fused to the alveolar bone (taking extraction risk into account)

• The wisdom tooth does not affect the orthodontic plan at all

✅ When is the best time to remove wisdom teeth?

The ideal time to remove wisdom teeth is before starting orthodontic treatment.

At the stage of making the orthodontic plan, the position, direction, and root shape of the wisdom teeth are accurately analyzed through X-rays or 3D CT scans, and if necessary, extraction is performed before the orthodontic appliance is attached.

This helps reduce appliance interference caused by extraction during orthodontic treatment, and because swelling and pain after extraction do not overlap with orthodontic treatment, the burden is lighter.

However, wisdom teeth with inflammation must be extracted promptly, and if wisdom teeth cause problems during orthodontic treatment, extraction in the middle of treatment can be considered.

Orthodontic treatment and wisdom tooth extraction can be confusing from the patient’s point of view. For someone without treatment experience, it is natural to wonder, “Why do I need to remove a wisdom tooth if it doesn’t hurt?”, or “Why should I even care about a wisdom tooth when all my teeth fit together well?”

But wisdom teeth are not simply “one inconvenient tooth”; they are a structure that can affect the entire dental arch and orthodontic plan.

Especially these days, digital orthodontic systems allow precise analysis of tooth alignment, skeletal structure, and alveolar bone condition, so the presence or absence of wisdom teeth can affect the efficiency, precision, and long-term prognosis of orthodontic treatment.

Criteria for determining whether to remove wisdom teeth before orthodontic treatment

Orthodontic treatment is not simply about making the teeth look neat; it is a precise treatment process that must satisfy function, aesthetics, and stability.

And in that process, “wisdom teeth” can become a small but very important variable.

Gwangjin-gu dental clinic, S Leader Dental Hospital, provides guidance on whether extraction is truly necessary after precisely diagnosing the wisdom tooth’s direction, its relationship with the gum bone, and its effect on the overall dentition before orthodontic treatment.

In addition, through a collaborative system between orthodontics and oral surgery, we help minimize treatment time by coordinating wisdom tooth extraction and the orthodontic schedule,

and we carefully plan tooth movement predictions, retainer design, and relapse-prevention strategies so that our patients’ time and costs are not wasted.

If you are concerned about your wisdom teeth, it may be time to consider a strategic approach that takes orthodontics into account, rather than simply deciding whether to extract them.
