Reasons for gum swelling

Causes of gum swelling

Solutions for gum swelling

If you have sudden gum swelling,

it is likely to be a temporary symptom,

but if the gum swelling persists,

it would be best to look for the reasons and causes of gum swelling

in gum disease caused by tartar, that is,

periodontal disease.

Reasons for gum swelling

If symptoms of sudden gum swelling appear,

the periodontal diseases to look into for a solution to gum swelling

are commonly called pyorrhea,

and can be divided into two types:

gingivitis

periodontitis

If tartar is not removed for a long time,

the space between the gums and teeth widens,

and bacteria invade that space and cause inflammation.

This is gingivitis,

a very common condition that affects

more than 50% of adults over 20,

more than 75% of adults over 35,

and as many as 80–90% of adults over 40.

The main cause of gingivitis is

plaque that forms on the surface of the teeth

and is not removed,

and excessive secretion of female hormones

can also expand blood vessels in the gums,

making bacterial growth and reproduction more active.

Because it is impossible to keep oral bacteria close to zero at all times,

even if you use oral hygiene products with plaque-removal effects,

plaque formation and the resulting tartar are inevitably produced.

That is why you need to get scaling regularly,

and if gingivitis is in its early stage,

it can be treated with scaling.

If gingivitis is not treated quickly,

it can develop into a more severe condition,

which is periodontitis.

When plaque and tartar reach the bone beneath the teeth,

not only gum swelling but also symptoms such as

loose teeth, bleeding, or severe bad breath may appear.

The cause of periodontitis is also

that plaque and tartar are not removed.

If plaque and tartar are not removed,

gingivitis develops and is left untreated for a long time,

it becomes periodontitis.

Therefore, to prevent further symptoms such as loss of jawbone and gum recession,

you must make an effort to manage oral hygiene through scaling.

Depending on the severity of periodontitis,

periodontal curettage, which removes deposits using a curette,

and gum surgery, which involves gum bone grafting and gum regeneration,

may be necessary.

As annual scaling is covered by health insurance,

we hope you can prevent gingivitis and periodontitis.
