Cheongdam-dong dental clinic: If left untreated, a gum abscess could put your teeth at risk.
Hello.
This is Ox Dental Clinic.

If your gums bleed when brushing,
or your gums are swollen and pus
comes out when you press them,
it may not be simple gum inflammation.
If these symptoms continue,
it is worth considering a
‘gum abscess (periodontal abscess).’
Today, Cheongdam-dong Dental Clinic
will explain what a gum abscess is,
why it occurs, and how it should
be treated.
What Is a Gum Abscess?
A gum abscess (periodontal abscess)
refers to a condition in which bacteria
infect the periodontal tissues around
a tooth, causing pus to collect.
In other words, a small
‘pocket of pus’ forms inside the gums.
This pus is an inflammatory byproduct
that forms as the body mounts
an immune response to fight bacteria.
As pus collects, the gums swell,
pain becomes more severe, and in serious cases,
the infection can spread enough
to cause swelling of the face.
If a periodontal abscess is left untreated,
the alveolar bone
(the bone that supports the teeth)
can be damaged, eventually causing
the tooth to become loose
or even fall out.

Causes of Gum Abscesses
A gum abscess can occur
for several reasons, but in most cases,
it develops when periodontal disease (gum disease)
has not been properly treated.
The main causes are as follows.
Tartar and bacterial infection
As tartar accumulates below the gums,
bacteria multiply and cause inflammation.
Worsening periodontitis
As the jawbone is destroyed and
periodontal pockets deepen,
pus collects.
Inflammation of the tooth root (apical periodontitis)
When severe tooth decay allows infection
to spread to the tip of the root,
pus may also collect in the gums.
Ill-fitting dental restorations
Food debris becomes trapped
between the gums and the restoration,
allowing bacteria to multiply.
Reduced immunity
It may also occur when fatigue, stress,
or systemic disease makes a person
more vulnerable to bacterial infection.

Common Symptoms of a Gum Abscess
A gum abscess may cause only mild
pain in its early stages,
but it gradually worsens.
If you experience any of the following symptoms,
you should receive dental care promptly.
Swollen gums and pain when pressed
Pus or blood coming from the gums
Severe bad breath
Tooth pain or a feeling of pressure when chewing
A sunken area in the gums, or pus bursting out when pressed
In severe cases, facial swelling or fever
These symptoms indicate that bacterial infection
has progressed beyond simple gum inflammation,
so prompt treatment is necessary.

Treatment for a Gum Abscess
Treatment should not stop at simply
‘draining the pus.’
The underlying cause of the inflammation
must be removed through appropriate treatment.
1️⃣ Drainage and disinfection
First, the swollen area is incised
or pressure is applied to drain the pus.
The infected area is then thoroughly disinfected
to prevent the inflammation from spreading.
2️⃣ Scaling and root surface cleaning
Tartar and bacterial plaque
that have accumulated inside the gums
are removed.
When necessary, periodontal cleaning
(Scaling & Root Planing) is performed
to clean areas deep beneath the gums.
3️⃣ Medication
Antibiotics or anti-inflammatory medication
may be prescribed together
to quickly reduce inflammation
and relieve pain.
4️⃣ Gum surgery (if necessary)
If the inflammation is deep or bone damage
is severe, periodontal surgery may be performed
to completely remove the affected area.
After surgery, bone grafting
or gum regeneration procedures
may also be performed.

How to Prevent Gum Abscesses
Once a gum abscess develops,
there is a high risk of recurrence,
so regular care is especially important.
✅ Brush properly at least twice a day
✅ Remove bacteria with dental floss and interdental brushes
✅ Have regular scaling every six months
✅ Replace ill-fitting dental restorations
✅ Reduce fatigue and stress,
and manage your immune health
In particular, if gum bleeding or swelling
occurs frequently, it is important
to have an early examination.
This is because by the time gum disease
causes severe pain, it has often
already progressed.
In Closing...
A gum abscess is not simply
a problem of swollen gums.
If left untreated, it can damage
the bone that supports the teeth
and lead to tooth loss.
