Seoul Hunhunhan Dental Clinic near Konkuk University Station is dedicated to preserving your natural teeth!
When oral problems such as
tooth decay or periodontal disease arise,
many patients consider treatments
such as extraction followed by
implant placement.
However, if problems are detected early
and treated appropriately,
natural teeth can often be preserved,
and extraction should be considered
as a last resort.
Despite advances in modern dentistry,
artificial teeth cannot fully replicate
every aspect of natural teeth,
so at Seoul Hunhunhan Dental Clinic
near Konkuk University Station,
we aim to help patients
preserve their natural teeth whenever possible.
Beyond simply treating teeth,
we strive to improve our patients' quality of life
and support their long-term oral health.
Below, we would like to share
a case in which we assisted a patient
with retreatment (re-root canal therapy)
at our clinic.
Initial Visit
The patient we would like to introduce
visited our clinic due to discomfort
in the rearmost lower-left molar.
The tooth in question had previously undergone
root canal treatment and crown restoration,
and signs of inflammation were observed.
For a more detailed analysis,
we also took CT images.
Root canal treatment involves removing
the infected nerve, disinfecting the canal,
and sealing it with filling material.
Re-root canal treatment requires
the removal of the material
previously used to seal the inside of the tooth—
a demanding process that can involve
high-difficulty cases.
For this reason, when a previously treated tooth
develops problems,
some clinics opt for extraction
and implant placement
rather than attempting retreatment.
At Seoul Hunhunhan Dental Clinic,
where preserving natural teeth is a core value,
we decided to attempt re-root canal treatment.
We first removed the existing crown,
and carefully removed the filling material
(G.P. cone) that had been placed
during the previous root canal treatment.
This is the completed re-root canal treatment.
We repeatedly disinfected the canal
all the way to its tip using instruments,
and after confirming that the inside
of the canal was thoroughly clean
through multiple steps,
we carefully filled it with filling material
to complete the treatment.
Completion
After confirming that the patient
had no discomfort or pain,
we placed a crown
to finalize the treatment.
At Seoul Hunhunhan Dental Clinic
near Konkuk University Station,
we provide thorough care
without overlooking even the smallest details,
and we work diligently to achieve
positive outcomes based on
extensive clinical experience and expertise.
We will continue to do our best
and keep learning and improving
to help preserve the natural teeth
of every patient who visits us.
