Since our teeth play various roles in life,

it is important to take careful hygiene measures

to prevent cavities and oral diseases.

For oral hygiene, brushing thoroughly is

important, but using floss or mouthwash can also

be helpful.

Sometimes people gargle with salt water to keep

the mouth clean. Today, let’s look at what benefits

gargling with salt water may offer, how to do it,

and the proper gargling method.

When you gargle with salt water, its anti-inflammatory

action provides a sterilizing effect, which may help

eliminate bacteria left in the mouth and reduce gum

inflammation.

In addition, it disinfects bacteria and germs remaining

in the throat, which may also help remove fine dust and

alleviate cough and nasal congestion symptoms caused by

a cold.

When gargling with salt water, lightly keep the salt

water in your mouth so that it reaches the inflamed area

inside the throat, then spit it out.

Because you may swallow a small amount of salt water

while gargling, doing it about once or twice a day is

appropriate, and it is also good to control the

concentration.

When using salt water for gargling, it is best to use fine

salt that dissolves well in water, dissolve it thoroughly in

warm water, and then use it.

If the salt concentration is too high or if the salt contains

seasonings, it may irritate the oral mucosa and worsen

inflammation, so caution is needed.

However, if you have mouth ulcers, salt water may be

irritating, so you should avoid it. For managing mouth

ulcers, it is better to brush with a low-foaming toothpaste.

It is also important to be familiar with the proper way to

use mouthwash. After using mouthwash, people often rinse

their mouths with water.

Ordinary commercial mouthwash contains disinfecting and

antibacterial ingredients, so it needs about 30 minutes to

work properly.

Therefore, it is better not to rinse with water after using

mouthwash. However, if you are 65 or older or are taking

medication for high blood pressure, it is better to rinse

your mouth after using mouthwash.

This is because aging or medication ingredients can dry out

the inside of the mouth, making dry mouth worse or causing

pain.

Some people also use mouthwash immediately after brushing,

but if you use it right after brushing, tooth discoloration

may occur, so it is better to wait 30 minutes after brushing.

Also, it is best to use mouthwash no more than twice a day,

and the proper amount is only a small amount, about 10–15

ml.

In addition, you should not gargle for too long; less than

30 seconds is appropriate, and if there are wounds inside

the mouth, it is better to avoid using it.

Today, we looked at the benefits of saltwater gargling,

how to do it, and the proper gargling method. Please refer

to the information above and take care of your oral hygiene.
