If You’re Worried That Root Canal Treatment Will Hurt, You Don’t Have to Be

Hello.

Are you looking for a dental clinic near Yangjae Station?

I’m Kim Moo-jin, the head director of D-Day Dental Clinic, where our goal is to provide treatments with as little pain as possible.

"Doctor, I heard root canal treatment is really painful... Will I be able to handle it?"

When root canal treatment comes up in the consultation room, many more people ask this question first than ask about the condition of their tooth.

A few days ago, one patient had postponed their appointment twice before finally coming in. They were clenching their hands tightly before even sitting in the chair.

I completely understand how they felt.

There are countless stories online about painful experiences, but stories about treatment that did not hurt are not as easy to find.

As inflammation worsens while treatment is delayed out of fear, some people end up in a vicious cycle that makes them even more afraid.

If you focus on reading for just three minutes, I believe I can help ease the weight of that worry.

  1. The truth behind the rumor that “root canal treatment is painful”

Let me first clarify the part that many people find confusing.

It is not the root canal treatment itself that hurts; it is the damaged tooth that has deteriorated to the point where root canal treatment is necessary.

When a cavity reaches the nerve, inflammation and pus build up inside the tooth, increasing the pressure.

That is the pain that throbs at night and keeps you from sleeping.

That is why, once an opening is made in the tooth and the inflammation is drained, many people say they feel as though they can finally breathe again.

Of course, if the inflammation has become severe, anesthetic may not work as effectively, which can make treatment more difficult.

But this is not because the treatment itself is painful; it is a problem caused by starting too late.

Ultimately, there are two key factors that determine the pain associated with root canal treatment.

✔ How quickly treatment begins,

✔ and how the anesthetic is administered.

  1. If you have been putting it off because you are afraid of the anesthetic injection

To be honest, many people say the anesthetic injection is more frightening than the root canal treatment itself.

However, most of the discomfort from anesthetic comes not from the needle but from the “speed” at which the anesthetic solution is injected.

Think of a balloon.

If you inflate it quickly in one go, it becomes taut as if it might burst, but if you inflate it slowly, the rubber stretches gradually without strain.

The same applies to the gums.

When the anesthetic solution is injected slowly, the tissue gradually adjusts, allowing the area to become numb with almost no sensation.

There is one more principle I always follow.

Whenever possible, I complete all procedures on the first day that could cause pain before sending the patient home.

That way, from the next appointment onward, you can continue treatment comfortably without pain.

Root canal treatment is usually carried out over several appointments. When the worry that “What if it hurts every time I come in?” disappears, the rate of completing treatment also changes noticeably.

  1. Yangjae Station Dental Clinic: The more intimidating the treatment, the more important the explanation

The reason people feel afraid is often not the pain itself, but the uncertainty of “not knowing when or how it will hurt.”

That is why, if there is a point when more discomfort than usual is expected, I always let the patient know in advance.

There is a completely different experience between hearing “You may feel some sensitivity from this point on” and not hearing it, even when the stimulus is the same.

Before treatment, I explain why this tooth needs root canal treatment

and how far we will proceed that day. We begin only after the patient understands and agrees.

From the initial consultation through completion, I handle the process personally as the head director,

so the explanation does not get interrupted midway, and there is no change in the person responsible for your care.

I believe not forcing treatment to continue beyond what is appropriate is also part of pain management.

To summarize, root canal treatment today is not something you need to postpone out of fear. It is more accurately a treatment that can become more painful the longer it is delayed.

The patient who had been clenching their hands tightly before even sitting in the chair said this after the first treatment:

“I wish I had come two months ago if I had known it would be like this.”

I hope your two months become much shorter.

I will provide a thorough explanation so that you can make your decision after understanding and feeling comfortable with the treatment.
