Bad breath treatment

Causes of bad breath

Bad breath clinic

As perceptions of enjoyment foods such as tobacco and alcohol

have changed,

the number of smokers and drinkers has increased regardless of gender,

and because coffee has now become almost like an essential supplement,

concerns about bad breath are unavoidable for modern people.

If you have bad breath that does not go away

even if you rinse frequently

even if you brush your teeth thoroughly,

Gangnam Sero Dental Clinic will tell you what to do.

Bad breath treatment

The causes of bad breath

are more than 90% due to oral causes,

and the biggest cause among them is,

of course, not brushing your teeth properly.

Although brushing differs depending on the type of food, it is best to do it within a short time after eating.

This is because bacteria in the mouth break down food

and release hydrogen sulfide.

Since this hydrogen sulfide smells like feces,

it is essential to eliminate bacteria through brushing.

If the cause of bad breath is not resolved even with brushing,

you can suspect tongue coating.

Tongue coating also releases hydrogen sulfide as bacteria multiply and accumulate,

and as mentioned, this hydrogen sulfide gives off a foul odor,

so it is best to remove tongue coating with a tongue cleaner.

If the cause of bad breath is not resolved even after removing tongue coating,

you need to check whether you have tonsil stones.

Tonsil stones are also related to bacterial activity

and produce a foul odor,

so it is good to remove stones stuck in the tonsils by coughing or using a cotton swab.

In addition,

there are easy ways to address the cause of bad breath at home,

such as replacing oral hygiene products,

using mouthwash,

taking oral probiotics,

and quitting smoking and drinking.

Dental bad breath treatment: Cavity treatment

As seen earlier in the causes of bad breath and bad breath treatment,

bacterial activity releases hydrogen sulfide

and causes a foul odor.

Cavities are also related to bacterial activity.

Because cavities occur when bacteria produce acid

while breaking down food,

which damages the teeth,

if you have cavities, it means bacterial activity is active,

and this may be why bad breath does not go away.

So the first dental bad breath treatment method is

treating cavities.

Dental bad breath treatment: Scaling

If you have periodontal disease,

it means oral hygiene management is poor

and bacterial activity is active.

Periodontal disease can occur when plaque and tartar build up.

Plaque is formed when numerous bacteria stick together

with certain components of saliva,

and tartar is what that becomes as it calcifies over time.

So the second dental bad breath treatment method is

scaling.

Dental bad breath treatment: Orthodontic correction for malocclusion

If you have malocclusion,

you may unintentionally activate bacterial activity.

Malocclusion can cause dry mouth,

creating an environment where bacteria can multiply,

and it can increase the frequency of food getting stuck,

which may activate the activity of the multiplied bacteria.

So the third dental bad breath treatment method is

orthodontic correction for malocclusion.

Causes of bad breath outside dentistry

So far, we have looked at easy ways to solve bad breath at home

and ways to solve bad breath at the dentist.

If you visited the dentist but

bad breath still has not been resolved,

you may need to suspect other medical departments outside dentistry.

Although more than 90% of the causes of bad breath are oral causes,

the remaining 10% of non-oral causes cannot be ruled out,

such as gastrointestinal disease, esophageal disease, diabetes, liver disease, sinusitis, rhinitis, pharyngitis, and tonsillitis.
