Hello.

I am Dr. Jeon Jun-hee, Director of Chiajikiimhee in Sinchon.

Have you ever had swelling in the gum area of a site that had previously received root canal treatment,

with something like a pimple appearing there?

If it did not hurt, so you just left it alone,

I recommend using this post as an opportunity

to visit a nearby dental clinic.

He is a young man preparing for the national exam.

He has a tooth on the lower right that underwent root canal treatment and was crowned.

Recently, his gum became swollen and painful,

and although the pus was incised and disinfected at the oral surgery clinic,

he said the pus started to fill again.

Pus originating from a root canal infection cannot be resolved by incising and disinfecting it. Fundamental treatment such as retreatment of the root canal or extraction is absolutely necessary.

After taking an X-ray to enlarge the problematic tooth,

an unpleasant black shadow around the root

can be seen.

At this time, CT is a very helpful diagnostic tool.

It helps us identify what was missed in the previous treatment,

and understand in advance the exact location and size of the inflammation.

Therefore,

it becomes evidence that allows us to roughly assess

whether retreatment of the root canal is possible.

For the retreatment of the root canal,

the crown was removed.

Fortunately, no decay had developed inside the crown.

If the retreatment goes well,

the tooth is in a condition where the crown can be placed again.

Retreatment of the root canal was started.

After cleaning down to the area with inflammation at the root tip,

it was possible to see pus rising along the root.

Retreatment continues until no more pus or other byproducts come out.

root canal materials,

and thoroughly opening the canal from end to end,

allows the inflammatory materials trapped at the root tip

to be discharged.

from that point on, the intervals between visits become fairly long.

You come in every 2 or 4 weeks to disinfect the inside and replace the medicine.

and treatment could be completed in 2 months.

A root canal-treated molar must live in the mouth for life,

colliding with the opposing tooth, food, and more.

A sturdy crown protects the tooth.

this photo was taken for follow-up observation.

The black inflammatory sac that had been hanging from the tip of the tooth root

can be seen to have almost completely disappeared.

Looking at the CT makes it even more satisfying.

The image above was taken before treatment,

and the image below is a cross-section of the tooth

taken 3 months after treatment.

It would be fair to say the tooth is almost completely healed.

Despite a busy exam-preparation schedule,

I would like to express my thanks to Mr. ㄱㅅㅇ for dedicating himself to treatment.
