Cheongdam Station Dentist: Do I Really Need Root Canal Treatment?

Hello, this is Director Sim Seong-hwan from Cheongdam Station Dentist.

"Do I really need root canal treatment?"

This is one of the most frequently asked questions in the clinic.

Even if a tooth looks perfectly fine on the outside, the nerve inside is often already damaged.

In the early stages, it may feel sensitive or cause a sharp twinge, and sometimes there are no symptoms at all. But at some point, the pain can suddenly become severe.

Root canal treatment is a way to preserve your natural tooth as much as possible during such critical moments. It removes the inflamed and damaged nerve tissue inside the tooth, disinfects the interior, and then seals it again for continued use.

Simply put, it is the “last resort” for saving a tooth without extracting it.

Recently, a patient in their 40s visited the clinic because of pain.

They said, “It started feeling sensitive a few days ago, and I couldn’t sleep last night,” while grimacing in pain. After examining the tooth, we found that the cavity had already penetrated deep into the nerve.

The patient was shocked, since it only looked like a small cavity from the outside. If left as it was, the inflammation would have spread further, and extraction followed by prosthetic treatment would have been unavoidable.

Fortunately, we started root canal treatment right away. Now that treatment has been completed, the pain is gone and the natural tooth is being well maintained.

Of course, not every tooth needs root canal treatment.

Sometimes people ask, “It only hurts a little. Do I really need a root canal?”

The answer is "not necessarily".

Root canal treatment is an effective way to save a tooth, but because it is also a relatively invasive procedure, accurate diagnosis and proper timing are more important than doing it unconditionally.

This is how we always provide care:

✔ If it is simply a cavity, we treat it while avoiding the nerve as much as possible.

✔ If root canal treatment is unavoidable, we explain the reason, the course of treatment, and the alternatives in detail.

✔ We discuss the least burdensome treatment plan together, taking the patient’s condition and concerns into account.

So when is root canal treatment needed?

🔹 When the cavity is too deep and has progressed to the nerve

If the gums are swollen or you repeatedly feel a sharp twinge, it may be a sign of internal damage.

🔹 When a tooth is cracked or broken

If the internal nerve is damaged due to trauma, inflammation may be progressing even if the tooth looks fine on the outside.

🔹 When inflammation occurs at the root tip

If inflammation develops around the root, pain may continue to recur, or you may feel a sharp twinge when chewing.

"What would we do if it were our family?" This is something we always ask ourselves.

"If this tooth belonged to my family, what would we do?"

That is why, rather than looking only at the result, we will carefully and honestly suggest the treatment that best fits your current dental condition, without delaying too long.
