Bad Breath Clinic: What If You Have Bad Breath Even Though You Brush Regularly? image 1

Even though you brush your teeth diligently every day,

if you still have bad breath,

find out about a

bad breath clinic

It can be embarrassing if you still have bad breath

even after brushing your teeth thoroughly.

Even though you have clearly brushed your teeth,

you may become self-conscious about the other person’s reaction during a conversation,

cover your mouth with your hand,

or lose confidence whenever you speak.

However, bad breath is not simply

a problem caused by failing to brush your teeth.

This is because there are various possible causes,

ranging from bacteria in the mouth, tongue coating, and periodontal disease

to an improper bite.

Today, we will look at the causes of bad breath that does not disappear even after brushing

and ways to address it!

Causes of Bad Breath

Bad breath, also known as halitosis, can broadly be divided into

causes within the mouth

and causes outside the mouth.

Most bad breath originates inside the mouth.

The main cause is volatile sulfur compounds produced

when bacteria in the mouth break down food debris or proteins.

Common oral causes of bad breath include:

Insufficient brushing and oral care

Tongue coating

Tonsil stones

Periodontal disease

Malocclusion

and others.

Cause of Bad Breath 1. Brushing and Oral Care

If you do not brush your teeth,

food debris and bacteria can interact

and cause bad breath.

When bacteria in the mouth break down food particles,

they produce volatile sulfur compounds such as hydrogen sulfide,

which causes an unpleasant odor similar to the smell of rotten eggs.

In addition, if oral care continues to be insufficient,

plaque can build up and harden into tartar,

increasing the possibility of cavities and gum disease.

Therefore, proper brushing

is the most basic way to manage bad breath!

Cause of Bad Breath 2. Tongue Coating

The white or yellowish material that builds up on the surface of the tongue

is called tongue coating.

The tongue has tiny projections,

and when food debris and bacteria accumulate between them,

tongue coating forms.

Tongue coating can also produce

volatile sulfur compounds during bacterial activity

and become a cause of bad breath.

Therefore, when brushing your teeth, it is important not only to brush your teeth

but also to gently clean the back of your tongue.

Using a tongue cleaner

can also help remove tongue coating.

Cause of Bad Breath 3. Tonsil Stones

If you have ever noticed something resembling yellow particles coming from your throat,

tonsil stones may be a possibility.

The tonsils contain small openings called tonsillar crypts.

When food debris and bacteria accumulate and harden in these openings,

tonsil stones can form.

Even when they are small,

tonsil stones can cause a distinctive, unpleasant odor.

They may be prevented through good oral hygiene and sufficient fluid intake,

but if they occur repeatedly or the odor is strong,

it is advisable to consider an examination by an otolaryngologist.

Cause of Bad Breath 4. Periodontal Disease

If bad breath continues even after brushing your teeth,

you should check your gum health.

If plaque is not properly removed,

it hardens into tartar.

When tartar accumulates over a long period,

it can progress into gum disease such as periodontitis.

When periodontal disease develops,

gum bleeding, inflammation, and pus may occur,

causing bad breath to persist.

If your gums bleed when you brush

or feel swollen or as though they are receding,

do not consider it merely a brushing issue.

It is advisable to receive an examination at a bad breath clinic.

How to Address Bad Breath: Scaling

Tartar, a major cause of periodontal disease,

is difficult to remove through brushing alone.

The treatment needed in this case is scaling.

Scaling is a treatment that removes

plaque and tartar attached to the tooth surfaces

and helps prevent gum disease and manage bad breath.

Some people think scaling scrapes away the teeth

or worry that their teeth will become sensitive.

However, a scaler is equipment designed to remove tartar;

scaling does not remove the teeth themselves.

Temporary sensitivity after scaling may also occur

because areas that had been covered by tartar become exposed and stimulated after the tartar is removed.

If you are 19 or older,

scaling may also be covered by national health insurance once a year,

so it may be worth looking into a bad breath clinic, right?!

Cause of Bad Breath 5. Malocclusion

Bad breath is related not only to gum or bacterial issues

but also to tooth alignment and the bite,

so you may need to look into a bad breath clinic.

With malocclusions such as protruding teeth, an underbite, or a weak chin,

or when teeth overlap severely,

food can become trapped easily

and areas that are difficult for a toothbrush to reach may develop.

During this process, plaque can accumulate

and increase the possibility of gum disease.

In addition, if the mouth cannot close properly because of its structure,

the mouth may become dry easily, which can worsen bad breath.

How to Address Bad Breath: Clear Aligners

Orthodontic treatment may be considered

to improve tooth alignment or malocclusion.

In particular, if you feel uncomfortable with orthodontic appliances

for aesthetic reasons,

clear aligners may be one option.

Clear aligners gradually move the teeth

using transparent, specially designed plastic appliances,

with the advantage of reducing the burden of appliance visibility in daily life.

However, not all malocclusions

may be treatable with clear aligners,

so you should confirm whether they are appropriate

through an accurate examination at a bad breath clinic.

What Is Causing My Bad Breath?

The way bad breath is addressed depends on its cause.

It may simply be an issue with brushing and oral care,

but it may also result from causes requiring dental treatment at a bad breath clinic,

such as tartar, periodontal disease, or malocclusion.

Therefore, if you have recurring bad breath,

rather than simply increasing how often you brush,

it is important to identify the exact cause.

Gangnam Saero Dental Clinic provides a range of treatments tailored to each person’s oral condition,

from basic care such as cavity treatment and scaling

to gum disease management and orthodontic treatment for tooth alignment and malocclusion.
