牙根暴露有办法补救（There is a remedy for root exposure） Root exposure is due to retraction of the gingival margin toward the tip of the tooth. This phenomenon is very common in clinical practice. Some root exposure occurs in individual teeth, and some root exposure occurs in most teeth. Clinically, the common causes of gingival recession and root exposure are the following: 1) brushing inappropriate use: brushing toothbrush toothpaste is excellent, the particles are too coarse. The seesaw type of cross brushing method. Because of mechanical stimulation and friction caused by withdrawal of gingival tissue, and root exposure, especially in canines and premolars part. (2): abnormal tooth position due to the effect of anatomical factors, labial bone plate makes labioversion teeth too thin, even with fenestration or bone cracking when the teeth were subjected to occlusal trauma, bone plate quickly absorbed, then the occurrence of gingival recession and root exposure. (3) effects of bite force and orthodontic force by excessive occlusal force in the teeth, or teeth orthodontic labioversion, the labial alveolar bone and gingival tissue thin, often occur in the gingival recession and root exposure. (4) bad prosthesis design: if the clasp is too low, the edge of the base is compressed, the crown margin is located in the gum, and the bad stimulation is also one of the causes of gingival recession and tooth root exposure. (5) periodontitis: one of the pathological changes of periodontitis is alveolar bone absorption. With the absorption of alveolar bone and the decrease of periodontal attachment, the gingival tissue height will decrease accordingly. In addition, after the treatment of periodontitis, the elimination of inflammation, or through periodontal surgery to remove part of the periodontal pocket, but also will make the gums recession, root exposure. The extent and extent of gingival recession are different, and the treatment methods and effects are different. For a small amount
