How long do you spend brushing your teeth?

Some people finish in less than a minute, others spend more than 10 minutes, and the time it takes to brush the teeth varies from person to person and depends on the timing of brushing.

So how long is the correct amount of time to brush one's teeth?

This time,I will discuss the appropriate amount of time to spend brushing your teeth.

At least 3 minutes required to brush teeth.

The minimum time required to brush teeth is 3 minutes.

There are a total of 28 teeth in the mouth, 32 if wisdom teeth are present, and to get every bit of dirt off each tooth, each tooth needs to be gently scrubbed with a toothbrush about 10 to 20 times per spot.

Based on this, if you brush all the front, back, and chewing surfaces of your teeth, you will inevitably need at least three minutes just to brush your teeth with a toothbrush.

In addition, it is difficult to remove stains between teeth using only a toothbrush; only 60% of tooth stains can be removed with a toothbrush alone. If you aim to brush your teeth closer to 100%,Flossing and interdental brush care required before brushing for 3 minutesIt is.

More important than "time," the point of tooth brushing is to remove stains.

Even though it is said that at least three minutes is necessary to brush teeth, this is only a rough estimate of the amount of time it takes to brush teeth properly.

In fact, the following three factors are more important than how much time you spend brushing your teeth.Don't get caught up in time alone, but be aware of these points as well.

• It is more important that the stains are removed than the time it takes to brush the teeth.
• Prolonged brushing is not good for the opposite.
• The time needed to brush teeth depends on the condition of the mouth.

It is more important that the stains are removed than the time it takes to brush the teeth.

Rather than being conscious of the time it takes to brush your teeth, focus on the technique used to remove stains with a toothbrush,It is important to consider whether the teeth are properly cleanedIt is.

It is common for people to inadvertently brush their teeth by not looking in the mirror when brushing or by not brushing in a certain order.

If you want to know if your toothbrush is removing the stains properly, you can ask your dentist to check when you get a cleaning.

Especially for those who find brushing their teeth long and tedious, brushing can be completed in a shorter time if they hone their toothbrushing technique and become more efficient at removing stains from their teeth.

We also recommend the use of a dye solution to know which areas are not being polished at home.

It dyes out areas that are not being polished, so when you have time, you can use it to self-check areas that are not being cleaned.

Prolonged brushing is not good for the opposite.

The tooth surface is hard, though, and not something that can be easily scraped off with a toothbrush,

Scrubbing hard with a toothbrush over time and repeatedly can scrape the teeth and damage the gums.

Prolonged tooth brushing can cause the following harmful effects.

• Wedge-shaped defect: The root of the tooth is shaved and gouged out in a wedge shape.
• Hypersensitivity: Pain is caused by grinding of the teeth, which facilitates the transmission of irritation, or by gum recession, which exposes the root of the tooth.
• Gingival recession: Gums fall back and the root of the tooth is exposed.
• Festoons: the edges of the gums become rounded and thickened.
• Abrasion: Gums are scraped and inflamed.

The time needed to brush teeth depends on the condition of the mouth.

The time required to brush your teeth isIt depends on the condition of the mouth.

For example, those with uneven teeth have difficulty removing stains with a toothbrush alone, so they need to use a one-tufted brush with small bristles or floss after the toothbrush, which requires more time.

In addition, if you have wire braces, you need to brush your teeth in three separate areas, above, below, and just above the wires, which increases the number of surfaces to be brushed, and therefore the time required to brush your teeth is much longer.

Best time to brush your teeth

The best time to brush your teeth isAt least twice a day, morning and evening, immediately after mealsis recommended.

At least twice a day, morning and evening

Brushing your teeth isDo this at least twice a day, once in the morning and once at night.

At night, saliva production is reduced because the body is in relaxation mode while sleeping,During the time it takes to wake up in the morning, a lot of bacteria such as caries and periodontal disease bacteria grow in the mouth.

An increase in the number of decayed and periodontally diseased bacteria is directly related to an increased risk of tooth decay and periodontal disease.

By minimizing the amount of bacteria that increase during sleep by brushing at night and removing the bacteria that increase during sleep by brushing in the morning, you can create a cycle that prevents the growth of cavities and periodontal disease.

Brush your teeth after lunch if possible.

In addition to brushing teeth in the morning and at night if possible,Brushing teeth after lunch is also recommended.It is.

There are always a variety of bacteria in the mouth, including caries and periodontal disease bacteria, which form a bacterial mass (biofilm) and are active. Biofilms are formed about 8 hours after eating, and over time they settle on the teeth and become difficult to remove.

Brushing after lunch also helps reset the mouth before new biofilm forms, reducing the risk of tooth decay and gum disease.

Brush immediately after eating

Brushing teeth is,It is recommended to do this as soon as possible after eatingIt is.

Some people believe that it is not good to brush teeth immediately after eating. This is due to the fact that the body's mechanism of "demineralization," in which the mouth becomes acidic after eating and the tooth surface slightly dissolves at the molecular level, and "remineralization," in which the tooth components that dissolved into the mouth due to demineralization return to their original state.

The perception is that tooth brushing interferes with remineralization because if the tooth is brushed before remineralization is complete, the tooth components dissolved by postprandial demineralization are lost.

However, demineralization is caused by food debris and plaque on the teeth in the first place,Leaving food debris and plaque until remineralization is complete encourages demineralization.

Therefore, it is more important to brush immediately after eating to eliminate the causes of demineralization and to minimize the time of demineralization itself.

Brushing immediately after filling your mouth with citric acid, orange juice, or other highly acidic substances can certainly damage your teeth, but once you gargle and brush, it is perfectly safe.

Some youtubers and websites are sending out that we should not brush our teeth for 30 minutes after eating due to TV shows, but this is not the view of our dentists.
