Why Do Gums Bleed? image 1

Brushing your teeth several times a day,

but if blood comes out of your mouth every time...

what would you do?

Most people might think, ‘Did I brush too hard today?’ or

‘Maybe it’s because I’m tired,’

and let it pass lightly.

But if gum bleeding happens repeatedly,

it may not be a simple temporary issue,

but a warning sign from your oral health.

Today, let’s look at

why gums bleed and how to prevent it. 🦷

⚠️Why do gums bleed?

Is it just because of brushing?

Of course, if you brush too hard

and irritate your gums,

temporary bleeding can occur.

In that case, using a soft-bristled toothbrush

and brushing with less force

may help you recover quickly.

But the problem is that if the bleeding continues

or happens repeatedly,

periodontal disease (gum disease) is often the cause.

🦠 The main causes of gum bleeding,

‘plaque’ and ‘tartar’

There are countless bacteria in our mouths,

even though we can’t see them.

When food debris and bacteria combine,

plaque forms,

and if it is not properly removed,

over time it turns into hard tartar.

As this tartar builds up between the gums and teeth,

it causes inflammation,

and as a result, the gums swell and bleed.

At first, there may be no noticeable pain, so it’s easy to let your guard down,

but if periodontal disease progresses,

the bone supporting the gums can be damaged,

and the teeth may become loose or even fall out...!

🦷 Regular scaling is

the most reliable preventive measure

Because periodontal disease progresses quietly

without obvious early symptoms,

it can be difficult to notice on your own.

That is why regular scaling and

checkups are more important than anything else.

Scaling removes not only the surface of the teeth

but also tartar hidden beneath the gums,

helping protect gum health

and making it easier to keep your teeth for a long time.

Also, if you are an adult aged 19 or older,

you can receive once-a-year insured scaling.

The eligibility period is based on January 1 to

December 31 each year,

and it is a benefit supported once a year.

If you miss the timing, the benefit for that year

will not roll over or accumulate and will expire.

Therefore, when planning scaling,

it is important to check the yearly schedule in advance

and receive treatment at the proper time.

💬Don’t leave bleeding gums untreated;

manage them early!

So far, we’ve introduced the reasons why gums bleed

and how to prevent it.

The gums are not just ‘the tissue around the teeth’

but the most important foundation that supports the teeth.

If even a small amount of bleeding continues,

it may not simply be fatigue,

but a SOS signal from your gums.

Therefore, if bleeding or swelling in the gums

repeats, don’t delay and visit a nearby dental clinic

for an examination.

Also, take care of your oral health with regular scaling and checkups,

and careful brushing! 💙
