Hello.

This is Seoul Dia Dental Clinic, where even the smallest discomfort in Magok is never overlooked.

This is Part 2 of the criteria for wisdom tooth extraction! In Part 1, we talked about cases where wisdom teeth do not need to be removed. If you haven’t seen it yet, it may be helpful to read Part 1 first.

Now, today’s topic. If you’ve read up to Part 1, this is probably the point where this thought starts to come to mind.

"So… in what cases do they absolutely need to be removed?"

So today, we’ll sum up exactly that.^^

If this applies, don’t put it off any longer

Magok Dental Clinic_Wisdom tooth gum swelling

  1. When the gums swell repeatedly

The gum around a partially erupted wisdom tooth swells once, then gets better, then swells again, then gets better again…

Does that pattern sound familiar?

Many people think, "It’ll probably get better again in a little while~" and let it go.

Here’s the key point. A temporary reduction is not the same as recovery. It is a sign that inflammation has already taken hold.

Whenever irritation occurs, it can flare up again, and the more it repeats, the wider the area of inflammation becomes. Treatment also becomes more complicated.

This is the exact timing that determines whether it can end small or become a bigger problem.

Magok Dental Clinic_Wisdom tooth pressure on adjacent tooth

  1. When the adjacent tooth also feels sensitive or painful

If the wisdom tooth hurts, but the neighboring molar also feels sensitive and uncomfortable, what then? It may not be only a problem with the wisdom tooth.

If a wisdom tooth is tilted and continues pressing on the adjacent tooth, it can gradually affect the root of that tooth as well.

As a result, not only the wisdom tooth but also the previously healthy neighboring tooth may end up needing treatment.

It is more common than you might think to end up treating two teeth because of one wisdom tooth.

We’ll cover this in more detail in Part 3, so please keep that in mind.

Magok Dental Clinic_Cavity in wisdom tooth

  1. When a cavity develops in a wisdom tooth

A wisdom tooth is located so far back that the toothbrush can’t properly reach it.

"Can’t I just brush really well?"

Unfortunately, that doesn’t work very well. The structure creates blind spots. So once a cavity starts, it progresses faster than you might expect. The bigger problem is when the cavity in the wisdom tooth spreads to the adjacent molar. In the tight space between two teeth that are pressed together, decay spreads quietly and quickly. Even if everything looks fine on the outside, it is often already progressing on the inside.

Magok Dental Clinic_Impacted wisdom tooth inflammation

  1. When an impacted wisdom tooth becomes inflamed

An impacted wisdom tooth is completely buried in the gums. Since nothing is visible on the surface, you may wonder, "Isn’t it fine?" But that is not necessarily true.

It can settle quietly inside, and then suddenly flare up as if inflammation has broken out all at once.

If inflammation develops around an impacted wisdom tooth, it can affect the jawbone, and in severe cases can lead to difficulty opening the mouth or swelling of the face.

This is why you should not feel reassured just because it is not visible.

Magok Dental Clinic_Orthodontic treatment

  1. When you are preparing for orthodontic treatment

Before starting orthodontic treatment, have you ever heard, "Please have your wisdom tooth removed first"?

There is a reason for that.

Wisdom teeth create a force that pushes other teeth inward. Even if orthodontic treatment aligns the teeth neatly, if the wisdom tooth continues applying that force, there is a high chance the teeth will shift again.

It is possible to prevent the situation where you work hard on orthodontic treatment, only for the wisdom tooth to cause things to move back. That is why checking the wisdom tooth condition before orthodontic treatment is so important.

What happens while you keep putting it off? By this stage, the scope of treatment becomes larger. A problem that could have ended simply at first changes direction as time passes.

That is because wisdom teeth do not suddenly get much worse; they tend to progress quietly.

So rather than waiting until it hurts a lot, it is better to check it when it feels vaguely uncomfortable.

That is the timing that determines whether wisdom tooth extraction becomes a bigger procedure or ends small.

At Dia Dental Clinic, we carefully examine the condition of the wisdom tooth with X-rays and a detailed examination, and then provide clear guidance based on whether extraction is needed now or whether it can be observed a little longer.

We are happy to help with consultations through Naver TalkTalk / reservations. Please feel free to check it without 부담.

Now, shall we briefly summarize today’s topic?

  • Repeated gum swelling → inflammation has already taken hold
  • Pain extending to the neighboring tooth → pressure has started
  • A cavity has developed → before it spreads to the neighboring tooth
  • Inflammation has developed in an impacted wisdom tooth → do not be reassured just because it is not visible
  • Orthodontic treatment is planned → be sure to check in advance

"It doesn’t hurt that much yet, so it should be fine" is the most dangerous thought. In the next part, I’ll explain in more detail what happens when wisdom teeth are left untreated. Have a day where you chew well and smile happily. ^^
