Revealing the three major misunderstandings about daily tooth brushing

　　Failure to brush your teeth scientifically will often lead to bad smell in the mouth, bleeding gums, loose teeth or loss of teeth. Therefore, brushing teeth must be scientific, and we must get rid of the misunderstandings of daily brushing.

　　Misunderstanding 1: Choose a hard-bristle toothbrush

　　Many people think that a toothbrush with hard bristles will be more beneficial to cleaning teeth and clean more thoroughly, so they often choose large-headed toothbrushes with hard bristles and many bristles. In fact, this idea is wrong. This is because if you choose a toothbrush with too hard and dense bristles, it will be difficult to remove tartar from the gaps and hidden surfaces of the teeth when brushing. The cleaning effect will not only be poor but will be seriously reduced. Moreover, hard-bristled toothbrushes often scratch the gums, causing gum bleeding, gum damage, or gum recession. Therefore, we should choose small-headed toothbrushes with soft bristles, and avoid brushing forcefully horizontally. Each toothbrush should not be used for more than one month. Otherwise, the toothbrush will be "extended" and breed a large number of pathogenic bacteria, leading to the occurrence of various oral diseases. After brushing your teeth, rinse the toothbrush with clean water several times, shake off the bristles, and place the brush head upward in a ventilated place.

　　Myth 2: You can brush your teeth for any length of time

　　Many people think that brushing teeth is an insignificant thing, as long as they brush every day, it doesn't matter how long it takes, and they don't want to waste more time on brushing their teeth. In daily life, some people brush their teeth for as short as tens of seconds and as long as more than ten minutes, until they retching while brushing. Brushing your teeth for too long or too short is not scientific enough. If the time is too short, you will be hasty and fail to achieve the purpose of cleaning your teeth. Brushing your teeth for too long will damage your gums. The scientific frequency and time of brushing your teeth should follow the "three threes", that is, brush your teeth three times a day, brush your teeth for 3 minutes after meals, and brush your teeth for 3 minutes each time, so that you can comprehensively achieve the purpose of eliminating dental plaque and cleaning your mouth.

　　Misunderstanding 3: Use the horizontal brushing method to brush your teeth

　　In the process of brushing your teeth, if you brush your teeth incorrectly, the effect of brushing your teeth will be different. Many people brush their teeth sideways. However, brushing sideways can seriously damage tooth enamel, dentin, gums and periodontal teeth. There is no fixed pattern for the correct way to brush your teeth. You just need to follow a certain order, such as brushing first up and then down, first outside and then inside, so as to completely clean the labial, buccal, palatal and lingual surfaces and the occlusal surfaces without missing a beat. Here, I would like to remind everyone that brushing your teeth is extremely important for oral health, and the only prerequisite is that the method must be correct. Otherwise, brushing your teeth will be in vain and may even damage your teeth. It is recommended to go to a regular dentist every six months. Hospital Get a preventive check-up and treatment.
