Root Canal Treatment

What Is Root Canal Treatment?

When decay is severe or a tooth suffers a strong impact, inside the tooth inflammation
occurs, and if inflammation inside the tooth is left untreated for a long time, at the root tip
inflammation develops. This inflammation is removed, and the empty space where it was
filling it with substitute material to keep the tooth functioning without extraction.
This is called root canal treatment.

The Goal of Root Canal Treatment

Root canal treatment is the last way to save a natural tooth, for tooth decay or
By treating or removing infected blood vessels and nerve tissue,
We try to keep the tooth in use without extraction.

Root Canal Treatment at EROM Dental

EROM Dental uses the 'endo-wiz' plasma root canal device
with heat generated using plasma and radio frequency, the inside of the root canal
sterilizing it.

Root Canal TreatmentWhen It Is Needed

  • When there is a risk of exposing the nerve during cavity treatment
  • When deep decay has inflamed the nerve
  • When a tooth is cracked or the nerve is damaged by an external impact
  • When retreatment is needed because a previous root canal treatment failed

Root Canal Treatment at a Glance

How do you decide whether root canal treatment is needed?

The Chief Director assesses the condition of the dental pulp in four stages: normal, reversible pulpitis, irreversible pulpitis and pulp necrosis. We have used the EndoWiz plasma root canal device since December 2023.

Reversible pulpitis can return to normal once the irritant is removed, while irreversible pulpitis and pulp necrosis require root canal treatment.

FAQ

Common questions before root canal treatment

What exactly is root canal treatment?

When severe decay or a strong impact causes inflammation inside the tooth and, left untreated, it spreads to the root tip, this treatment removes the inflammation and fills the empty space with substitute material, keeping the tooth functional without extraction. We see it as the last way to save a natural tooth.

When is root canal treatment needed?

It is done when there is a risk of exposing the nerve during cavity treatment, when deep decay has inflamed the nerve, when an external impact has cracked the tooth or damaged the nerve, or when a previous root canal treatment failed and retreatment is needed.

What are the steps of root canal treatment?

After identifying the tooth with a damaged nerve, we remove the decay, clean out the root canal and fill it. After treatment, we restore the weakened tooth with a crown to protect it.

Do I have to get a crown after root canal treatment?

A tooth that has had root canal treatment is weaker because its inner tissue has been removed, so in most cases it is restored with a crown after treatment so it can withstand chewing forces.

How does EROM Dental's plasma root canal device (EndoWiz) work?

We use EndoWiz, a plasma root canal device by Apro Korea. It sterilizes the inside of the root canal with heat generated by plasma and radio frequency.

Since when have you used the EndoWiz device?

We have used it since December 2023.

Can root canal treatment be finished in one day?

It depends on the condition of the nerve and the extent of infection, but our plasma root canal device sterilizes the inside of the root canal, which in some cases helps shorten treatment or finish it on the same day.

How does treatment for a cracked tooth differ by stage?

At stages 1–2, where it hurts only occasionally when chewing or every time you chew, early restorative treatment such as a crown or overlay can often finish things without root canal treatment. At stage 3, with pain even at rest, root canal treatment followed by restoration is needed, and at stage 4, where the crack has reached the root, the tooth is difficult to save and must be extracted.

Can the decision change to extraction during root canal treatment?

Yes. Even if we start root canal treatment judging that the crack is not deep, if the crack is found to extend into the root during treatment, the tooth may be difficult to save and may need to be extracted.

Does root canal treatment hurt?

Most dental treatment is done under anesthesia, so once it takes effect you will not feel much pain even during root canal treatment. The injection itself may hurt, but only for a moment.

I think my previous root canal treatment was not done well. Is retreatment possible?

Yes, it is possible. When a previous root canal treatment has failed and retreatment is needed, that is also one of the cases requiring root canal treatment. We check the condition through examination and then advise you on retreatment.

Is a tooth that cannot be saved with root canal treatment extracted right away?

If the tooth can recover, we prioritize delaying extraction as long as possible with treatment, including root canal treatment. However, if a crack has reached the root and the tooth cannot improve, we recommend extraction without delay.

Can I book root canal treatment even if my departure is soon?

We use a plasma root canal device to help shorten root canal treatment or finish it on the same day, so we recommend a consultation planned around your schedule.

Is root canal treatment also patient-led?

Yes. We show you with photos and test results why root canal treatment is needed and how it will proceed, explain whether the tooth could be saved without it, and then begin treatment.

How can I find out the cost of root canal treatment?

The cost depends on your teeth and the scope of treatment, so we give you the exact amount at consultation after examination.

Can I get root canal treatment without an appointment on weekday afternoons?

On weekdays from 2 PM to 4 PM, we offer walk-in hours when you can be seen right away without an appointment. You can also have a consultation during this time to check whether root canal treatment is needed.
