Many people choose a hard bristled toothbrush when brushing their teeth. They always think that the cleaning effect of such toothbrush will be better, but what they don't know is that the hard bristle toothbrush often scratches the gums, causing gum bleeding, gum damage or gingival atrophy. Therefore, we should choose those toothbrushes with softer hair and avoid forced horizontal brushing. Each toothbrush should not be used for more than one month, otherwise, a large number of pathogenic bacteria will be bred and various oral diseases will occur. After brushing the teeth, wash the toothbrush repeatedly with water, dry the bristles, and place the brush head upward in a ventilated place.
Many people think that brushing teeth is a matter of no importance. As long as you brush your teeth every day, it doesn't matter how long it takes. They don't want to waste more time on brushing their teeth. In daily life, some people brush their teeth for the shortest time of dozens of seconds, the longest more than 10 minutes, until the occurrence of retching brush so far. Too long or too short brushing time is not scientific enough. If the time is too short, you can't clean your teeth. If you brush your teeth too long, you will hurt your gums. Scientific brushing times and time should follow the "three three", that is, brushing three times a day, 3 minutes after meals, and 3 minutes each time, so as to completely eliminate dental plaque and clean the mouth.
In the process of brushing teeth, if the way of brushing teeth is not correct, the effect of brushing teeth will be different. Many people brush their teeth horizontally. However, brushing horizontally will seriously damage enamel, dentin, gums and periodontium. There is no fixed pattern for the correct way of brushing teeth. As long as the teeth are brushed in a certain order, such as from top to bottom, from outside to inside, the lips and buccal surfaces, palatal and lingual surfaces and occlusal surfaces can be completely washed without omission.
