"Of course, you should eat breakfast first and then brush your teeth, otherwise your mouth will become dirty again after eating. Wouldn't it be a waste of time?" A domestic website has conducted a relevant survey, and the results show that 79.9% of people brush their teeth first

"Of course, I brush my teeth first and then eat breakfast, otherwise my mouth will be so dirty after a night!"

"Of course, I eat breakfast first and then brush my teeth, otherwise my mouth will become dirty again after eating. Isn't it a waste of brushing?"

Early in the morning on the weekend, Xiaojiu's roommate argued that " should I eat breakfast first and then brush my teeth first and then eat breakfast ". It’s strange that Chinese people are used to brushing their teeth first and then having breakfast after getting up, but watching foreign films and TV dramas you will find that foreigners often eat breakfast directly after getting up and brush their teeth only after finishing their meal.

A domestic website has conducted a relevant survey, and the results show that 79.9% of people brush their teeth first and then eat breakfast, 11.3% of people eat breakfast first and then brush their teeth, and the rest of people do not have a fixed habit, it mainly depends on their mood.

So, which method is more beneficial to oral health?

1. How many bacteria are there in the mouth if you don’t brush your teeth a day?

Have you ever thought about how many bacteria will grow in your mouth if you don’t brush your teeth for a day?

According to Dr. Walter Loesche of the University of Michigan, under normal circumstances, there are more than 20 billion microorganisms in our mouths. From teeth to gums, to the tongue, the inner side of the left and right cheeks, oral microorganisms are distributed in every corner of the mouth.

But this number is not fixed, it will increase as the time for not brushing teeth is longer. Dr. Loesche said that oral microorganisms can increase by nearly five times in a day. If you only brush your teeth once in 24 hours, the initial 20 billion will become 100 billion , and there will be hundreds of billions of them being swallowed into your stomach.

The microorganism species in the mouth have about 700 kinds of , including bacteria, fungi, etc. Some microorganisms are beneficial, while others can cause tooth decay , tooth decay , bad breath and other diseases. Brushing teeth can remove some oral bacteria, but they will soon reproduce and even form plaque, which is why we need to brush our teeth regularly.

2. Drinking water when you wake up is equivalent to drinking bacteria?

Some people say that drinking a glass of water first when you wake up in the morning can replenish water and promote gastrointestinal motility. But some people are also worried that drinking water when you get up in the morning will cause bacteria to be drunk into your stomach, which is not good for your health.

In fact, the latter statement of is wrong.

First of all, Most of the bacteria in the mouth are harmless . We have swallowed countless microorganisms when we swallow saliva, and generally there will be no effect. What's more, there are a large number of bacteria in the intestines, which have the function of regulating microenvironment , so the bacteria you drink are not important.

Secondly, after the bacteria in the mouth are washed into the stomach, they cannot enter the blood directly, and they will be blocked by the barrier of the gastrointestinal tract. After reaching the stomach, most microorganisms will be "killed" by gastric acid , and only a few can survive.

What's more, the plaque bacteria on the teeth are very stubborn and difficult to wash away with water, so don't worry.

So, should I have breakfast first or brush my teeth first?

Dental Department of the Sanjun General Hospital Director of the Periodontal Disease Department of said that after getting up, you should first rinse your mouth with clean water, , then eat breakfast, and then brush your teeth after eating. If you brush your teeth first and then eat breakfast, the time for the teeth to stay clean is relatively short, because after breakfast, a large number of bacteria grow again. Eat breakfast first and then brush your teeth. The teeth will be kept clean for a relatively long time, which is more conducive to oral health.

The British Dental Association believes that whether you brush your teeth first or eat breakfast first when you wake up in the morning, the impact is actually not big. The important thing is the frequency of brushing your teeth. It is best to brush your teeth twice a day, once after getting up in the morning and once before going to bed at night.

However, for people suffering from oral diseases such as periodontitis and pulpitis, it is recommended to brush your teeth first and then eat breakfast, and clean your mouth after breakfast.

3. What does it mean to dream of losing teeth?

Peking University A study published in the European Journal of Clinical Research found that not brushing teeth properly will increase the risk of multiple diseases and the risk of death of .

Researchers followed up 512,715 subjects for 10 years. The results showed that 9.3% of subjects rarely or never brush their teeth, mostly older men. From the perspective of the risk of disease, the risk of cardiovascular disease in these people increased by 12% , and the risk of cancer, chronic obstructive pulmonary disease, and cirrhosis of also increased by 9%, 12%, and 25%, respectively.

More importantly, has an increase of 25% of all-cause death risk .

Interestingly, some people often dream of loose teeth or fall off. Is this also related to the risk of death? Or "Dreams of losing teeth and having funerals at home", indicates that something unfortunate will happen?

At present, there is not much scientific explanation for this phenomenon. But one thing that is certain is that if we dream of losing our teeth, we will feel anxious and worried .

A Israeli Ben-Gurion University has conducted research on "Dental Dreams". It was found that Dreams of tooth loss are a manifestation of tooth tension , which is related to tooth stimulation, but has nothing to do with sleep health and mental health.

In other words, it may be that your teeth have potential physiological diseases , or has physical stimulation such as molars .

Experts suggest that if you often dream of teeth falling off and are very anxious, you can talk to your doctor about your concerns. If you have teeth grinding or have a pain after getting up, you can go to the dentist.

A good tooth can not only give a person's image a bonus, but also reduce the risk of oral diseases. Therefore, we don’t have to worry about brushing our teeth first or having breakfast first. We should focus on oral cleaning, brushing our teeth in the morning and evening, and learn to brush our teeth scientifically.
