Under normal circumstances, the teeth can be slightly loose within one millimeter, which is a kind of physiological mobility, with the role of teeth. Deciduous teeth replacement is also a normal performance, generally do not need to deal with. Abnormal tooth looseness is mainly caused by periodontitis. Inflammation around the roots leads to swollen gums, alveolar bone absorption and gingival recession, with the consequent consequences of a series of symptoms such as loose teeth, increased seams, and food impaction. In addition, the teeth by traumatic impact or biting hard objects gnawing, so that the elastic fibers around the roots damaged will make the teeth loose or even shift. Individual teeth bite strength too large or have molars, bitten teeth of bad habits, long-term error occlusion can also cause teeth loose. If the teeth
