Gum Inflammation Treatment, Daechi-dong Yonsei Garden Dental Clinic

Hello. I am Dr. Yoon Jung-won, director of Yonsei Garden Dental Clinic, located in Daechi-dong, Gangnam-gu.

Have you ever experienced bleeding from your gums when brushing your teeth or noticed that your gums are more swollen than usual?

At first, many people do not worry too much and simply move on.

"Did I brush my teeth too hard?"

"Is it because I have been tired lately?"

"It will probably get better in a few days."

These are easy conclusions to reach.

However, if gum bleeding continues to recur or is accompanied by swelling and redness, it is important to check whether gum inflammation may be present rather than assuming that the symptoms are simply due to fatigue.

Today, we will discuss the causes and symptoms of gum inflammation, the difference between gingivitis and periodontitis, and gum treatment—topics that people looking for a dentist in Daechi-dong often ask about.

Why do gums become swollen and bleed?

One of the most common causes of gum inflammation is plaque and tartar that build up around the teeth and gums.

Plaque is a bacterial film that forms on the surface of the teeth. It can usually be removed by brushing, but plaque can easily remain in areas that are difficult for a toothbrush to reach, such as between the teeth and along the gumline.

If this plaque is not removed for a long time, it can harden and become tartar.

Because tartar is difficult to remove with regular brushing alone, it may remain around the teeth and gums and continue to irritate the gums.

When inflammation develops in the gums during this process, symptoms may include:

  • Redness of the gums

  • Swollen gums

  • Bleeding when brushing

  • Increased gum sensitivity

  • Worsening bad breath

Therefore, if your gums bleed, it is important to identify the cause of the bleeding rather than simply brushing more gently.

How are gingivitis and periodontitis different?

When discussing gum inflammation, two terms that are often heard are gingivitis and periodontitis.

Gingivitis refers to a relatively localized inflammatory condition affecting the gums.

Typical symptoms include swollen or reddened gums and bleeding when brushing.

On the other hand, if the inflammation progresses and affects not only the gums but also the tissues supporting the teeth and the alveolar bone, it may develop into periodontitis.

As periodontitis progresses, symptoms may include not only gum bleeding but also:

  • The gums appearing to recede

  • A sensation that spaces are developing between the teeth

  • Bad breath

  • A sensation that the teeth are loose

  • Discomfort when chewing

Therefore, if swollen and bleeding gums recur, it is important to check how far the inflammation has progressed.

If my gums bleed but do not hurt, is it okay?

This is a question we receive often.

Gum disease is not necessarily accompanied by severe pain.

For this reason, some people assume that treatment is not needed simply because their gums bleed without causing pain.

However, gum bleeding may be a sign that inflammation is present in the gums.

In particular, if bleeding occurs repeatedly whenever you brush or continues when you use dental floss or an interdental brush, it is a good idea to have your gum condition checked.

Rather than waiting until the symptoms become severe before beginning treatment, it may be more beneficial to identify the cause and manage it at an early stage.

What happens if gum inflammation is left untreated?

Early gum inflammation may improve with appropriate care and treatment.

However, if the inflammation persists for a long time and begins to affect the deeper tissues around the teeth, the situation may become more serious.

As periodontitis progresses, the alveolar bone supporting the teeth may become damaged.

As the gums recede, the teeth may appear longer or spaces between the teeth may become wider. In severe cases, this may lead to loose teeth.

Ultimately, gum health is closely related not only to the condition of the gums themselves but also to maintaining your natural teeth for a long time.

Therefore, when consulting a dentist in Daechi-dong about gum inflammation, it is important to examine the overall condition of the teeth and the surrounding gums, rather than looking only at the current swelling or bleeding.

Gum Inflammation Treatment at a Dental Clinic

How does a dental clinic in Daechi-dong check for gum inflammation?

Not every patient with swollen and bleeding gums requires the same gum treatment.

First, the dentist checks for gum swelling and bleeding, as well as the condition around the teeth. Depending on the situation, the condition of the periodontal pockets and alveolar bone may also be evaluated.

When necessary, X-ray examinations may be used to assess the condition around the teeth that is difficult to check by visual examination alone.

These examinations help determine how far the gum inflammation has progressed and allow an appropriate treatment method to be selected.

Can scaling alone sometimes be enough?

Having gum inflammation does not always mean that complex gum treatment is necessary.

If the inflammation is relatively early and plaque and tartar are the main causes, the condition of the gums may improve with scaling and proper oral hygiene alone.

However, if tartar has become deeply embedded below the gums or periodontitis has progressed, additional periodontal treatment may be needed depending on the condition.

Therefore, the important thing is not to receive scaling unconditionally, but to receive treatment suited to the current condition of your gums.

Scaling in Daechi-dong at Yonsei Garden Dental Clinic

Why can your gums appear to recede further after scaling?

Some people feel that their teeth look longer or that spaces have developed between their teeth after scaling.

When a significant amount of tartar has accumulated, it may have been filling the spaces between the gums and teeth. After it is removed, more of the teeth may appear exposed than before.

In addition, as gums that were swollen due to inflammation return to a healthier state, the swelling may subside, creating the sensation that the gums have receded.

Therefore, it is difficult to conclude that scaling has worsened the gums simply because these changes have occurred.

Rather, it is important to examine the condition of the gums and tartar before treatment as well.

How should you manage your gums to prevent gum inflammation?

To maintain healthy gums, regular care at home is just as important as treatment received at a dental clinic.

The most basic step is proper brushing.

It is particularly important to brush carefully along the boundary where the teeth and gums meet and between the teeth.

For spaces between the teeth that are difficult to manage with brushing alone, using dental floss or an interdental brush may also be helpful.

Even if you do not have any particular gum symptoms, it is also a good idea to have the condition of your teeth and gums checked regularly at a dental clinic.

Daechi-dong Dentist: If Your Gums Are Swollen and Bleeding

A single episode of gum bleeding does not necessarily mean that you have serious gum disease.

However, if gum bleeding or swelling keeps recurring, or if symptoms such as bad breath, gum pain, or loose teeth occur as well, it is best not to ignore them.

In particular, gum disease is important to detect and manage at a relatively early stage, rather than after the symptoms have become severe.

If you are looking for a dentist in Daechi-dong, rather than simply addressing uncomfortable gum symptoms, consider whether the clinic can also assess how far the gum inflammation has progressed and examine the condition of the teeth and surrounding gums.

If gum bleeding that you normally considered insignificant continues to recur, this may be a good opportunity to have your gum condition checked.
