Hello.

Are you looking for a dentist because of a cracked tooth?

This is Oh Tae-hoon, the chief director of D-Day Dental Clinic.

A little while ago, one patient said to me,

Doctor, I think my tooth has a crack

but it didn’t hurt much, so I just left it alone.

But after examining it, the infection had already progressed to the nerve.^^;

It seems that many people think that even if a tooth breaks or cracks,

it is fine as long as it does not hurt right away.

Since there is no major discomfort when chewing,

they think it is okay to leave it alone.

But that is a truly dangerous judgment.

If you leave a crack or break in a tooth untreated,

it often ends up requiring root canal treatment.

That is why today I will explain in detail why cracked teeth

need to be treated immediately,

and how you should respond.

If you read this article to the end,

I am sure it will be very helpful.

  4. Cracked tooth,

why is it so dangerous?

If a tooth cracks or breaks, you can first think of it as the protective barrier having collapsed.

The outermost layer of the tooth, the enamel, is damaged, exposing the inner dentin.

The problem starts here.

Food debris and bacteria continue to enter through the cracked area.

Especially in molars, because the chewing force is so strong, the cracked area gradually widens.

If you repeat the act of chewing hundreds of times a day, a small crack eventually leads to a large fracture.

  1. Cracked tooth,

the process leading to root canal treatment

What happens if you leave a cracked tooth untreated?

Let me explain it step by step.

At first, you may only notice sensitivity.

It is just a brief, sharp sensation when you eat something cold or hot.

Up to this point, simple treatment is usually enough.

But if it continues to be neglected, bacteria begin to penetrate deep inside the tooth.

The infection progresses past the dentin and into the pulp.

At this stage, throbbing pain begins to appear.

The biggest problem starts from this point.

When the pulp becomes inflamed, the pressure inside the tooth rises rapidly, causing severe pain.

Many people describe it as pain so severe that they cannot sleep at night.

At this stage, root canal treatment becomes unavoidable.

The infected pulp must be completely removed, disinfected, and then filled with an artificial material in a complex procedure.

  1. Cracked tooth,

how is it treated at D-Day Dental Clinic?

In cases of cracked teeth or fractures, accurate diagnosis is the most important thing.

Even if it looks minor to the eye, the damage often has already progressed internally.

That is why we always determine the extent of the damage through a precise examination.

We use 3D CT scans and intraoral cameras to accurately diagnose the condition of the tooth.

We also show it directly to patients and explain the current state in detail.

The treatment method depends on the extent of the damage.

If it is an early stage, a simple restorative treatment such as resin or an inlay may be enough.

But if it has already progressed deeply, more active treatment is needed.

What matters most is helping patients understand the treatment process and feel reassured.

We explain everything transparently, from the treatment plan to the expected duration and cost.

I always tell my patients this.

"Teeth are tissues that cannot naturally recover once damaged. So even a small problem is best resolved as quickly as possible," I say.

In fact, most people who receive treatment early are able to finish with simple treatment.

On the other hand, those who delay for a long time often end up needing complex treatment.

If you suspect a cracked tooth or fracture, do not delay.

Even if it seems fine for now, the chances are high that it will develop into a bigger problem over time.

Above all, early treatment is much more advantageous for patients in terms of both money and time.

Do not let a small problem grow into a bigger one,

and please get an accurate diagnosis

as soon as possible.
