If severe loosening, periodontal sequence treatment can be carried out first, and if the effect is not good, the method of extracting the affected tooth is mostly used to avoid adding unnecessary burden to the adjacent teeth; 3, trauma: loose teeth caused by trauma, if mild loosening, anti-inflammatory drugs can be taken to reduce the load and stimulation, once the inflammation subsides, the teeth may be able to restore the solid state by themselves. If the loosening is serious or dislocation, displacement, should first reset the teeth fixed, and then targeted treatment, short-term disable this tooth, etc., after 1-2 months of treatment may return to normal; 4, geriatric gum recession: gums will gradually aging with age, atrophy, is a normal physiological phenomenon, usually this situation does not require special intervention, daily attention to the mouth light hygiene, good dental care, such as regular knocking action.
