Everyone has their own chewing “preferences”, but if you prefer to chew on one side too much, beware that it can cause “big and small face” and lead to a variety of dental diseases such as dental disease, missing teeth, bite problems and so on. Once you find yourself chewing on one side of the habit, it is best to go to the hospital to check whether there are related oral problems. Usually, you should strengthen the exercise of bilateral chewing habit and correct unilateral chewing as soon as possible. Recently, 16-year-old Fang was troubled, he found that other people could swallow eggs when their mouths were opened wide, but he could only stuff things in small mouths. He came to the hospital for examination and found that Fang’s face had obvious deformity, the right half of his face was big with bulging bite muscle, but the left half of his face was flat and the teeth were not arranged neatly. When simulating chewing, the right temporomandibular joint made a “gurgling” sound, and the mouth could only fit a finger’s width when it was opened wide, and it was painful when it was opened wide again. The cause of the problem was the decay of Fang’s left molar when he was 6 years old. It was judged that Xiaofang had TMJ disorder syndrome, which was caused by the painful left side chewing because he was afraid to chew the left side teeth after the decay of left molar. Lateral chewing causes many kinds of dental diseases Lateral chewing will not only cause big and small face, but also cause various dental diseases. According to statistics, people with sideways chewing habits often have a variety of lesions in the mouth, such as dental disease, missing teeth, bite problems, and so on. This is mainly caused by several reasons. 1, side-chewing makes the unused side of the teeth due to the lack of food friction and a large amount of tartar and tartar accumulation between the teeth, easy to occur caries and cause gingivitis, periodontitis. 2.Lateral chewing makes the side not used or less used lack of chewing exercise, the facial tissue development is poor, resulting in facial left and right development asymmetry, especially for children and adolescents in the growth and development period has a greater impact. 3, long-term lateral chewing will make both sides of the temporomandibular joint activities uncoordinated, resulting in relationship dysfunction, such as the appearance of open and closed mouth joint popping, pain, mouth opening restrictions and other symptoms. Warm tip: When you find yourself with side-chewing habits, it is best to go to the hospital to check whether there are related oral problems. And people who already have dental diseases should be treated in time to restore the normal biting and chewing function of teeth. Usually, we should strengthen the exercise of bilateral chewing habit and correct unilateral chewing as soon as possible.
