How to Use Mouthwash Correctly!

In our busy daily lives,

many people use mouthwash,

an oral cleansing product,

to keep their mouths feeling fresh.

It is convenient to use before going out, after meals, or whenever bad breath is a concern,

which is why many people reach for it.

However, some people use mouthwash instead of brushing their teeth

or use it incorrectly.

When used properly, mouthwash can support oral care,

but improper use may instead place a burden on oral health,

so caution is needed..!

Today, we will walk you through

how to use mouthwash correctly!

Mouthwash products

vary in their ingredients and functions,

but they generally contain antibacterial ingredients

that help reduce bacteria in the mouth

and fluoride,

which can help prevent cavities.

Because it leaves your mouth feeling refreshed after use,

it may also help manage bad breath.

However, please remember that mouthwash is only

an aid that supplements toothbrushing.

It can support oral care when used appropriately

along with brushing.

How to Use Mouthwash

Let's take a look!

For adults,

using mouthwash once or twice a day is generally appropriate.

Usually, you should hold about 10–15 mL in your mouth,

rinse thoroughly for approximately 30 seconds,

and then spit it out.

The recommended amount and duration

may vary slightly from product to product,

so it is best to check the instructions before use.

However, using mouthwash too frequently

or excessively over a long period

may reduce not only harmful bacteria in the mouth

but also beneficial bacteria.

This can disrupt the balance of microorganisms in the mouth,

so it is important to use mouthwash the recommended number of times.

In addition, products containing alcohol

can make the mouth dry.

When the mouth becomes dry,

bad breath may actually become worse.

If you feel dryness after use,

choose an alcohol-free product

or rinse lightly with water.

Some people also use mouthwash

immediately after brushing their teeth.

When surfactants in toothpaste

come into contact with certain ingredients in mouthwash,

they may cause tooth staining.

Therefore, it is best to avoid using mouthwash immediately afterward.

Rather than using it right after brushing,

we recommend waiting approximately 30 minutes

before using mouthwash.

Extra caution is also needed with children,

as adult mouthwash may be too irritating.

When a child uses mouthwash,

choose a product specifically made for children,

and have a guardian supervise them

to ensure that they do not swallow it.

That covers how to use mouthwash correctly.

Above all, the most important point is

that mouthwash cannot replace brushing your teeth!

Mouthwash cannot directly remove plaque

attached to the surface of the teeth.

To prevent cavities and gum disease,

thorough brushing with a toothbrush

must always be the foundation of oral care.

For the spaces between teeth that a toothbrush cannot reach well,

please also use dental floss or interdental brushes.

It is also a good idea to pay close attention to maintaining a clean mouth

through regular dental checkups and professional scaling.

Protect your healthy teeth for many years

with proper brushing habits,

appropriate mouthwash use,

and regular dental checkups and scaling. ❣🙏🏻
