If your tooth throbs or

reacts sensitively to

cold water or hot food,

you may think it is

just a simple sensitivity symptom.

However, if the pain

continues for a long time even after

the stimulus is gone, or is severe enough

to make it difficult to sleep at night,

there may be inflammation

in the internal nerve tissue.

When considering Yeomchang Station root canal treatment,

rather than starting treatment

simply because there is pain,

it is important to identify

the actual cause correctly.

What Causes Pain?

One of the most common causes

of tooth pain is advanced tooth decay.

If decay progresses through the enamel and dentin

and reaches near the pulp,

the tooth may react sensitively

to cold or hot foods.

In the early stages, there may be

brief sensitivity only when stimulated,

but if the inflammation worsens,

the tooth may throb even when left alone,

and the pain may become more severe at night.

What Symptoms Indicate the Need for Root Canal Treatment?

If discomfort remains for a long time

after pain is triggered by cold water or hot food,

or if the pain keeps recurring

even after taking pain medication,

pulp inflammation may be suspected.

If a particular tooth hurts when eating,

or if pain is felt even when the tooth

is lightly tapped,

the inflammation may have

progressed to the area around the root.

When the nerve becomes completely necrotic,

the pain may sometimes decrease,

but the inflammation can continue to spread

to the root tip and jawbone.

Therefore, even if the pain has gone away,

we recommend confirming through an examination

whether you are in a condition requiring

Yeomchang Station root canal treatment.

Why Is a Diagnosis Before Treatment Important?

Before root canal treatment,

an oral examination and radiographs are used

to assess the depth of the decay,

the shape of the tooth roots,

and whether inflammation is present

at the root tip.

In some cases, the tooth causing the pain

may be different from the tooth

that is actually responsible for it.

In particular, molar pain may be caused

by a neighboring tooth or a sinus problem,

so judging only by the location of the pain

may result in inappropriate treatment.

The need for root canal treatment

should be determined after examining

the teeth, gums, and bite.

What Is the Root Canal Treatment Process?

Root canal treatment involves accessing

the inside of the tooth after local anesthesia

and removing infected nerve tissue.

✅The narrow and complex canals

inside the tooth root are then cleaned,

and disinfected with an irrigation solution.

✅Depending on the condition of the inflammation,

temporary medication may be placed,

and treatment may be performed

over multiple appointments.

✅Once the inside of the canals is clean,

the empty space is filled with dental material

and sealed to prevent bacteria

from entering again.

A tooth that has undergone root canal treatment

may become structurally weaker,

which can increase the risk of fracture.

In particular, molars, which receive significant

chewing forces, are often protected

with restorative treatment such as a crown.

How Should You Care for Your Tooth After Treatment?

For several days after root canal treatment,

the tooth may feel sore,

or there may be discomfort when eating.

This usually improves over time,

but if the pain becomes severe

or the gums and face become swollen,

you should have the condition checked

at a dental clinic.

Even if the pain in daily life has decreased,

stopping treatment suddenly

may cause the inflammation to return,

so treatment should be completed.

After Yeomchang Station root canal treatment,

it is important to care for your teeth

using dental floss and an interdental brush,

and to regularly check the condition

of your teeth and restorations

through routine examinations.

Because tooth pain can have various causes,

please have your condition evaluated

through a dental examination

and then choose the appropriate treatment.
