Hello. This is Seonjeongneung Station Dental Clinic.

If your tooth is throbbing, if you feel pain even when you are still, and if you have become especially sensitive to cold or hot foods,

many people first think of

“root canal treatment.”

At the same time, many people put off treatment because of worries such as

“It seems like it will hurt,”

“Will they shave down a lot of the tooth?”

“I heard root canal treatment weakens the tooth.”

Root canal treatment is not something to fear and avoid;

it is the final conservative treatment step to preserve the tooth as much as possible.

If it is done in time, you can keep your natural tooth without extraction,

and because it also has a major impact on your quality of life afterward,

an accurate understanding is especially important.

What is root canal treatment?

Root canal treatment is a procedure that preserves the tooth by removing infected tissue, cleaning and disinfecting the inside thoroughly, and then filling it, when the pulp (the nerve and blood vessel tissue) located deep inside the tooth has been damaged by inflammation or infection.

Even if it looks like only a small cavity on the outside,

there are many cases where inflammation has already progressed to the nerve inside.

If this condition is left untreated, the pain gradually worsens,

and the inflammation can spread to the gum bone, eventually leading to extraction.

In other words, root canal treatment at Seonjeongneung Station Dental Clinic is not a treatment chosen right before giving up on the tooth,

but a necessary process to protect it.

If you have these symptoms, you should consider root canal treatment.

▪️Persistent throbbing pain even when still ▪️Pain that gets worse at night ▪️Pain that lasts a long time after hot or cold stimulation ▪️A feeling of deep tooth pain when chewing ▪️Swollen gums or the presence of pus

In particular, just because the pain has decreased does not mean the condition has improved.

There is also the possibility that the nerve has already necrotized and the pain has temporarily dulled, so if this timing is missed, the inflammation can progress more deeply.

Root canal treatment: why is precision important?

Root canal treatment at Seonjeongneung Station Dental Clinic is not a treatment that simply ends with “removing the nerve.”

The root canal system inside the tooth has a very thin and complex structure, so how accurately the infected area is removed and disinfected greatly affects the treatment outcome.

▪️Whether the canals were properly removed all the way to the end ▪️Whether even invisible microscopic infected areas were cleaned out ▪️Whether bacterial contamination was blocked during treatment

If even one step in this process is missed,

pain may remain after treatment or retreatment may become necessary.

That is why root canal treatment is one of the procedures where the medical team’s experience and the treatment environment are extremely important.

Why root canal treatment requires multiple visits

People often ask, “Why can’t it be finished in one visit?” Root canal treatment usually requires 2 to 3 or more visits, because the inside of the tooth needs to be stabilized step by step.

  1. Removal of the infected nerve and initial disinfection
  2. Placement of medication to check the inflammatory response
  3. Internal filling and sealing
  4. Protection afterward with prosthetic treatment such as a crown

Rather than forcing everything to be finished at once,

checking the condition of the tooth and proceeding step by step with treatment at Seonjeongneung Station Dental Clinic is much more stable in the long term.

Why should a tooth be covered after root canal treatment?

A tooth that has undergone root canal treatment at Seonjeongneung Station Dental Clinic loses its pain, but because the internal tissue has been removed, it can become relatively weaker than a natural tooth.

That is why crown treatment is often considered after treatment to protect the tooth.

This is not simply for appearance, but serves important roles such as ▪️Preventing fractures caused by chewing force ▪️Preventing bacteria from re-entering through microscopic cracks ▪️A protective measure to maintain the completed root canal treatment for a long time

Root canal treatment: is it really very painful?

The part many people worry about most is pain. But because this is the process of treating pain caused by inflammation, most cases see pain decrease after treatment.

Pain is minimized through sufficient anesthesia before treatment,

and even if discomfort is felt during treatment, it can be adjusted immediately.

In fact, if treatment starts after waiting until the inflammation has become severe, recovery may become more difficult.

Why Lucid Dental Clinic is more careful with root canal treatment

Lucid Dental Clinic sees root canal treatment not as a simple pain-relief procedure, but as a key treatment for using the tooth for a long time.

▪️Providing only the treatment that is truly necessary through precise diagnosis ▪️Careful treatment planning that considers the internal structure of the tooth ▪️Sufficient explanation so the patient can understand the treatment process and condition ▪️A conservative approach that also considers care after treatment

Because root canal treatment at Seonjeongneung Station Dental Clinic deals with areas that are not visible, how carefully it is performed makes a difference over time.

If you are about to receive root canal treatment, please keep this in mind.

▪️Do not feel reassured just because the pain has disappeared ▪️A quick diagnosis reduces the scope of treatment ▪️Accurate root canal treatment lowers the possibility of retreatment ▪️A plan that includes post-treatment care is important

A choice to protect the tooth before giving up on it

Root canal treatment can be the last chance to save the tooth. If you hesitate, thinking you should endure a little longer, and miss the timing of treatment, that choice can lead to extraction.

Lucid Dental Clinic thinks first about how long and how comfortably you can use the tooth, rather than only about immediate treatment.

If you have been told that root canal treatment is needed but are still hesitating, we recommend accurately checking your current tooth condition and calmly receiving a consultation.

A choice to protect your tooth, please consider that beginning together at Lucid Dental Clinic.
