Hello~

This is Yoon Tae-ho from Seoul Bardi Dental Clinic.

My teeth feel sensitive

Just as many people experience bleeding gums,

a lot of people also feel tooth sensitivity.

The causes of sensitivity vary, such as cavities or gum problems.

Among them, if your teeth hurt when you drink hot water,

it may be a bad sign.

This is a helpful post for patients who experience tooth sensitivity.

My teeth are so sensitive that I can't eat ice cream.

That's a normal reaction~ haha

As you get older,

your tooth roots may wear down and become sensitive,

and after drinking a cold beverage, it can be considered within the normal range.

240221 If the tooth wears down, it becomes close to the nerve, so it feels sensitive!~

However, some patients say their teeth hurt when they drink hot soup or coffee.

This is... not a good sign.

Tooth pain triggered by hot water is a more serious problem~

It may be an early symptom of pulpitis.

There may be a problem with the nerve inside the tooth!!

A representative symptom of pulpitis, where there is a problem with the tooth nerve,

is a throbbing pain when eating hot food~

Pulpitis refers to inflammation of the nerve and blood vessel tissue inside the tooth.

Deep cavities

Tooth cracks or trauma

Leakage of infection around old restorations

Repeated tooth sensitivity that gradually worsens

There are many possible causes!!

When pulpitis develops, there is nowhere for gas to escape from inside the tooth,

so it becomes extremely painful.

Even after taking painkillers all night, you may still feel uncomfortable

Becoming sensitive to stimuli may be a sign that the nerve has already been significantly damaged.

Are the symptoms getting worse?

You need to monitor them and get treatment~

At first, it may only feel sensitive when drinking hot water,

but if it throbs even while resting, it means the symptoms are progressing!

If your teeth are sensitive to hot water, in most cases, root canal treatment

can improve the condition by treating the inflammation inside the pulp.

However, if left untreated, pus may form at the root tip,

and symptoms such as feverishness, pain, and facial swelling may also occur.

If the nerve has already necrosed,

it becomes even more difficult to treat

231214 If the tooth nerve dies, it can be confirmed on X-rays

Should I just put up with it...?

If it only hurts when drinking hot water and not all day,

at first it may seem like it gets better if you adjust your diet.

But while you endure it, the inflammation continues to progress.

Because inflammation has developed inside the tooth, it will not naturally get better~

To summarize...

Pain with hot water is a more dangerous sign!

Sensitivity to cold water is a natural phenomenon!

Inside the tooth, it may be showing the reaction of "Please treat me~~"

Since this is different from simple sensitivity,

please keep that in mind.

I hope this was helpful,

see you in the next post~!
