Hello!

This is Seoul Vardi Dental Clinic.

Today, this is a case where, after root canal treatment,

proper prosthetic treatment was not received,

and the tooth split in half.

Many people

say, “I feel fine now after the root canal,”

and feel relieved, then no longer

come back to the clinic.

If you do not come to the dental clinic in between,

we do contact you

and provide sufficient explanation about the

possibility of fracture,

but

if you do not come in,

we have no other way.

All we can do is keep trying to contact you...

A tooth that has received root canal treatment

is in a weakened state,

with only the outer surface of the tooth remaining.

So if you do not receive the

protective "crown" treatment,

we really do often see in clinical practice

cases where it eventually goes "snap"

and breaks apart.

We hope this case serves as an opportunity

to remind you of the importance of care

after root canal treatment.

At the first visit

Neglect after root canal treatment

It hurts every time I chew.

The tooth is very worn down,

and there are many signs of time,

so some sensitivity may be present,

but

after an accurate examination,

there are sharp symptoms every time

you chew.

Pain in a specific area of the tooth during chewing

Possibility of pulpitis due to nerve inflammation

Planned root canal treatment if symptoms persist after observation

When resting it is fine,

but because it kept hurting every time I chewed,

we started root canal treatment.

What is root canal treatment?

It is a treatment that removes the infected or

damaged pulp (nerves and blood vessels)

inside the tooth, thoroughly disinfects

the inside,

then fills it with special materials used in the dental clinic,

and finishes the treatment by placing a crown.

You can think of it as the treatment

done right before extraction,

in order to save the tooth.

Because it was a molar, we allowed enough time between steps,

went through the process of disinfecting and thoroughly cleaning

the infected pulp,

and completed the treatment.

And the parts that had been temporarily filled

during treatment were firmly finished

with a core.

What is core?

It is the process of reinforcing the weakened

inside of the tooth with a hard material after root canal treatment,

and it is an essential step before placing the crown.

And...

Neglect after root canal treatment

The patient no longer came to the dental clinic.

“Now that I’ve had the root canal, it doesn’t hurt...

There’s nothing urgent...

It’s not uncomfortable right away, so it should be okay, right?

Going to the dentist every week is

too exhausting...

There must have been many such thoughts.

The crucial reason why you should not neglect care after root canal treatment

  1. The tooth structure becomes weaker

: During the treatment process, the tooth walls become thin,

so if a strong chewing force is applied,

the tooth can break as it is.

  1. If it breaks, extraction is the only option

: Because this is the final treatment that can save the tooth,

if a problem occurs, there is really no choice but extraction..

Therefore, after root canal treatment,

you must!!!

finish the crown treatment

and protect the tooth.

What we expected

happened..

Neglect after root canal treatment

The patient came to the clinic saying

that the tooth had broken.

While eating, with a "crack" sound,

the tooth fractured across horizontally, and

as a result of the diagnosis,

it was no longer possible to save this tooth.

At this stage,

we needed to choose

the best option we could do.

Since it was no longer a tooth that could be saved,

we decided to treat it with extraction followed by an implant.

Root canal treatment is

the last chance

to save the tooth.

But to make proper use of that chance,

you must complete the crown treatment

as well.

There are also cases where people have root canal treatment

and do not get a crown. But that is a decision

made by me, the dentist, after an accurate diagnosis.

So,

please stop thinking, “It doesn’t hurt, so it must be okay...,”

and make sure you complete the treatment.

You cannot make precious natural teeth

a second time.

If you have a tooth that received root canal treatment

and is being left untreated,

please come in before it is too late.

Thank you.
