Did you know? There is a surprising relationship between some dental diseases and tooth brushing. “Wedge defect” may sound strange, but it is actually a common disease among middle-aged and elderly people in China. Many people brush their teeth with toothpaste containing rough abrasives for a long time, and this part of the teeth will be worn into the sink. When people reach middle age, the wear and tear penetrates deep into the dentin, and the teeth become easily irritated and painful when they encounter hot, cold, sour or sweet; if the wear and tear continues, it will lead to pulp inflammation, root inflammation and even tooth fracture. Surprisingly, this dental disease and bad brushing habits are closely related. Which brushing habits are not right? One is the wrong way to brush your teeth. Many people like to brush their teeth horizontally and brush with too much force, both of which can cause damage to teeth and gums. Second, the wrong toothbrush is used. Using toothbrushes with hard bristles and unrounded tips can also aggravate wedge-shaped tooth defects. Third, use toothpaste containing rough abrasives. Some toothpastes contain abrasives that are too rough and hard. Brushing with this toothpaste every day is no different from polishing your teeth with coarse sandpaper. In order to reduce tooth wear and improve oral health, it is recommended that you adopt the correct brushing method (vertical brushing method), use a soft health care toothbrush, and choose toothpaste with high quality abrasives as soon as possible, so as not to let brushing become a bad thing!
