I believe that many people have been educated since childhood that they should brush their teeth before eating in the morning, which can better maintain oral hygiene. However, there is another view that we have brushed our teeth before going to bed and didn't eat at night. After waking up the next day, our mouth is relatively clean. Brushing our teeth after eating in the morning is more conducive to removing food residues, which is more beneficial to oral health. So which method is more beneficial to oral health?

after brushing your teeth before going to bed, will bacteria still grow in your mouth after one night? It's a pity that bacteria do breed in your mouth when you sleep

The purpose of brushing your teeth is actually to remove food residues and redundant bacteria in your mouth. In fact, there is a certain ecological balance in your mouth, and we can't clean up all the bacteria in your mouth. Developing a good habit of brushing your teeth can keep your teeth healthy and avoid tooth decay and gum bleeding in your mouth.

why does the mouth still breed bacteria after brushing your teeth to sleep? The human oral saliva has a good bacteriostatic effect, and when the body goes to sleep at night, the saliva secreted by the oral cavity will be greatly reduced, so that bacteria in the oral cavity will take the opportunity to multiply, and many people have the habit of snoring at night, which is easy to accelerate the growth of oral bacteria.

Therefore, even if many people brush their teeth before going to bed at night, when they wake up the next morning, they will still feel that their mouth is not very refreshing, which is caused by the decrease of saliva secretion in the mouth at night and the growth of bacteria, so it is necessary to get up and brush their teeth in the morning.

So is it better to brush your teeth before meals or after meals?

Actually, brushing your teeth before meals and after hair are both possible. But the difference is that after eating, food will have a certain effect on the teeth, which will lead to the change of PH value in the human mouth. Brushing your teeth just after eating may damage the enamel, which is not conducive to the health of your teeth. Therefore, it is better to brush your teeth about half an hour after meals.

However, with the accelerated pace of life, many people are very precious in the morning. They are busy squeezing the subway and going to work. Few people can wait for half an hour before brushing their teeth. If you don't brush your teeth, bacteria in your mouth will multiply, which is not conducive to the health of your teeth. Therefore, for most people, it is recommended to brush your teeth before meals, which is more convenient and faster, and is also beneficial to maintain oral hygiene.

Although many people know the importance of brushing your teeth, in fact, if you brush your teeth incorrectly, it may destroy the structure of your gums and cause your teeth to loosen, especially for older people. So what should we pay attention to when brushing our teeth?

what should I pay attention to when brushing my teeth?

pay attention to keep the posture of brushing your teeth up and down. For convenience, many people like to brush their teeth with left and right saws, which makes their hands more convenient and hard, and at the same time, they feel that they can brush their teeth cleanly. But in fact, it is easy to loosen the gums and it is difficult to brush the gums clean, which is not conducive to removing oral bacteria. Therefore, it is suggested that when you brush your teeth, try to keep the posture of brushing up and down, which can better clean your mouth and protect the health of your teeth.

choose warm water to brush your teeth. Warm water can dissolve the substances in toothpaste to a greater extent, and give full play to the sterilization effect of toothpaste. Especially for people who are prone to gum bleeding in dentine hypersensitivity, it is not suitable to brush their teeth with cold water, which may stimulate the gum area and lead to tooth ache.

Therefore, everyone should try to brush their teeth with warm water at ordinary times and brush their teeth for about 3 minutes, which can better remove bacteria in the mouth. In addition, everyone's toothbrush should be replaced in time, generally speaking, it takes about 3 months, and changing a toothbrush is more beneficial to oral hygiene.
