In our daily life, there are often some ladies who love beauty in order to keep their teeth white, brushing hard for a long time; some people choose toothbrushes with hard bristles on purpose in order to clean their teeth completely; some people often brush their teeth perfunctorily and finish the process of brushing in less than a minute; some even brush their teeth multiple times a day or do not brush their teeth once in a few days. In fact, these practices are wrong. If you can’t brush your teeth scientifically, it will often lead to bad odor in the mouth, bleeding gums, loose teeth or loss. Therefore, brushing should be scientific, we must get out of the misunderstanding of daily brushing. First, choose a hard-bristled toothbrush Many people think that a toothbrush with hard bristles will be more beneficial to the cleaning of teeth and will clean more thoroughly, so they often choose some hard-bristled and hairy big-headed toothbrush. In fact, this idea is wrong. This is because if the bristles of the toothbrush are too hard and too dense, it will be difficult to clean off the tartar in the gaps and hidden surfaces of the teeth when brushing, and the cleaning effect will be seriously reduced instead of bad. Moreover, hard-bristled toothbrushes often scratch the gums, leading to gum bleeding, gum damage or gum recession. Therefore, we should choose those toothbrushes with soft bristles and small heads, and avoid brushing across with force. Each toothbrush should not be used for more than one month, otherwise, the toothbrush “overdue”, will breed a large number of pathogenic bacteria, resulting in the occurrence of various oral diseases. After brushing your teeth, rinse your toothbrush repeatedly with water, shake the bristles, and place the brush head up in a ventilated place. Second, the length of time you can brush your teeth Many people think that brushing is an insignificant thing, as long as you brush every day, it does not matter how long it takes, and do not want to waste more time for brushing teeth. In daily life, some people brush their teeth for a few tens of seconds at the shortest and more than ten minutes at the longest, until the dryness of the brush occurs. The time of brushing is too long or too short is not scientific enough, too short, haphazardly, can not achieve the purpose of cleaning teeth; brush too long, will hurt the gums. Scientific brushing times and time should follow the “three three”, that is, brush 3 times a day, 3 minutes after meals, each brush 3 minutes, so that you can fully achieve the purpose of eliminating plaque, clean mouth. Third, brush teeth to take the horizontal brush method in the process of brushing teeth, if the way to brush teeth is not correct, the effect of brushing teeth will be different. Many people brush their teeth in a horizontal way, not knowing that brushing horizontally can seriously damage tooth enamel, dentin, gums and periodontal. There is no fixed pattern for the correct way to brush teeth, as long as you follow a certain order, such as first up and then down, first outside and then inside, without missing the lip and cheek surface, palate and tongue surface, and occlusal surface can be completely scrubbed. Here, we remind everyone that brushing is extremely important for oral health care, and the only prerequisite is that the method must be correct, otherwise brushing is also a white brush, and even damage to the teeth, it is recommended that every six months to the regular hospital for a preventive examination and treatment.
