Sillim-dong Dental Clinic – Everyday Habits That Harm Your Teeth!

Hello, I am Shin Seung-hwan,

Director of Yonsei U-Line Dental Clinic.

As we go through life, we often come to realize that

many things we have diligently done for our health

were, in fact, not actually beneficial to it.

This applies not only to overall health,

but also to oral health.

Today, I would like to take some time

to review the everyday habits that can harm your teeth.

Are there people who binge-eat when they are under a lot of stress?

Binge eating can negatively affect the stomach and intestines,

but when it comes to your teeth, eating snacks frequently

and repeatedly throughout the day is even more harmful than binge eating.

Snacks are often sweet foods.

When you consume sugar,

harmful bacteria use it to produce acids,

and these acids are said to cause tooth decay.

Therefore, whether you have a meal or a snack,

if you have eaten something, you need to brush your teeth

so that the acids are removed

in order to maintain healthy teeth without cavities.

If you keep drinking coffee after meals

and continue eating snacks whenever you feel hungry,

continually supplying sugar to your mouth,

cavities are more likely to develop.

Eating too frequently over multiple occasions

or constantly snacking can be harmful

to your dental health,

so you should be careful.

Did you know that mouth breathing—breathing through your mouth—

can also become a bad habit that harms your dental health

without you realizing it?

You mainly breathe through your mouth

when your nose is blocked due to rhinitis or a cold.

​In this case, you may sleep with your mouth open

so that you can breathe more comfortably while sleeping.

In fact, the inside of your mouth needs to remain moist

in order to stay healthy.

When the inside of your mouth becomes dry,

plaque and tartar can form more easily,

creating an environment where harmful bacteria

can become more active.

Therefore, mouth breathing or the habit of keeping your mouth open

can be considered harmful to your teeth.

If possible, consciously breathe through your nose

rather than your mouth,

helping your mouth stay moist

with sufficient saliva.

This can help support your oral health.

If your mouth is dry,

it is a good idea to drink water frequently.

Remember that you should choose plain water

rather than sugary juice or soft drinks.

​Finally, eating fruit frequently

can also be considered a bad habit for your teeth.

Fruit is rich in vitamins, sweet, and delicious,

so many people enjoy it.

However, sweetness means that it contains sugar.

Citrus fruits and other sour fruits

also contain acids.

​Sugar creates an environment where cavities can develop more easily,

while acidic foods can contribute to tooth erosion.

Therefore, after eating fruit,

make an effort to rinse your mouth with water.

Because of the acids, it is better to brush your teeth

30 minutes later rather than immediately afterward.

It is surprising that the bad habits we have without realizing it

can become major causes of damage to our dental health.

Please keep the points discussed today in mind

and take care to maintain your oral health.
