Hello, this is Dia Dental Clinic in Magok-dong.

These days, with the warm sunlight, it’s the kind of season that makes you look in the mirror an extra time.

The clear weather lifts your mood a little, too,

but at the same time, you may become more aware of the small signals your body is sending.

But have you ever thought something like this?

“Lately, my gums bleed a little every time I brush.”

“My gums seem swollen. Is it just stress?”

It could simply be because you’re tired,

but in fact, it may be a quiet warning called ‘periodontal disease.’

So starting today, Magok-dong Dia Dental Clinic will be sharing all the information you need to protect your gum health through a ‘periodontal disease series.’

The first story,

starts with ‘What is periodontal disease?’

and the difference between ‘gingivitis’ and ‘periodontitis.’

What is periodontal disease?

Magok-dong Dental Clinic_Progression of Periodontal Disease

Some people call it pyorrhea, and others call it gum disease,

but the correct name is perio-don-tal dis-ease.

Just hearing the name sounds unfamiliar and a little scary, doesn’t it?

People often ask, “Perio? What is that?”

To break it down literally, here’s what it means.

“Che(齒)” means tooth, and “ju(周)” means surrounding or around.

In other words, all the tissues around the teeth are collectively called the periodontium.

Let’s look at it in a little more detail.

  • Gingiva, or gums (the soft pink part we all know well)

  • Alveolar bone (the bone that supports the teeth; you can’t see it, but it’s very important)

  • Periodontal ligament (tiny fibers that connect the tooth and bone)

  • Periodontal pocket (the small space between the gum and tooth; the key trouble spot)

If inflammation occurs in any of these areas,

that is what we call ‘periodontal disease.’

Magok-dong Dental Clinic_Plaque

Periodontal disease starts with tiny bacterial debris,

that is, plaque.

The slimy buildup that forms when you eat and don’t brush,

that’s the culprit.

If these bacteria are not removed and keep accumulating, they turn into hardened tartar,

work their way into the gap between the teeth and gums, irritate the gums, and cause inflammation.

If the inflammation stays only in the gums, it is called ‘gingivitis.’

If it spreads to deeper tissues such as the periodontal ligament and alveolar bone, it is classified as ‘periodontitis.’

Differences between gingivitis and periodontitis

  1. Gingivitis

– Inflammation limited to the gums

This is the early stage of periodontal disease.

At this stage, the gum bone and ligaments have not yet been damaged.

Let’s briefly look at the main features.

The gums swell, turn red, and bleed when brushing.

There may be slight bad breath, but there is almost no pain.

Gingivitis at this stage can be reversed.

With scaling, proper brushing, and oral care, the gums can recover.

But if left untreated, it can move on to the next stage: periodontitis.

  1. Periodontitis

– Inflammation that extends beyond the gums and into the bone

Magok-dong Dental Clinic_Periodontitis

This is a condition where gingivitis has progressed and deeper structures have been damaged.

It is not just a gum problem; it is a serious disease that can even dissolve the bone that supports the teeth.

The gums may loosen, and pus can come out when pressed.

Bleeding happens often, pain may be felt, and bad breath becomes severe.

In severe cases, the teeth become loose, and in serious cases, they may even fall out on their own.

At this stage, brushing alone can no longer restore the gums.

Treatment may include scaling, subgingival curettage (removal of inflammation inside the gums), laser treatment,

and if necessary, gum surgery.

Periodontal disease usually has almost no symptoms, and only a slight feeling of swelling.

If these symptoms are left untreated, the bone slowly dissolves and is resorbed.

And the problem is that once gum bone is lost, it does not grow back.

Do not wait until your gums hurt or bleed; correcting the small warning signs right away is the most important prevention.

Gums are like the ‘soil’ for your teeth.

Just as even a strong tree cannot stand if the soil collapses,

healthy teeth last longer when the gums are healthy.

Let’s briefly review the beginning and types of periodontal disease that we covered today.
