Whether or not loose gums can be restored depends on the specific oral condition and the cause of the loosening. If it is external forces, apical periodontitis, gingivitis caused by loose gums can be restored; and periodontitis with alveolar bone atrophy and resorption caused by it is difficult to restore. 1. External forces: If the gums are loose under external forces, and the surrounding teeth and gums, periodontal tissues are very healthy, then within half an hour of timely reset, do a good job of fixing the loose teeth, the teeth are likely to be fixed, avoid chewing hard objects with the affected teeth, 1-2 months after the roots can gradually restore stability. 2. Periapical periodontitis: If the tooth loosening caused by acute periapical periodontitis, a large amount of inflammatory secretion will be formed around the root of the tooth, so that the tooth appears to be loosening or floating, need to be opened as soon as possible to drain the pulp, so that inflammatory substances are discharged into the oral cavity, remove the pulp root canal disinfection, complete endodontic treatment to completely remove the inflammation of the tip of the tooth, the tooth will no longer loosening. 3. Gingivitis: If the tooth loosening is caused by gingivitis, it is necessary to carry out peri-coronary rinsing of the inflamed area, medication, and removal of inflammation of the gums, and the tooth loosening will be significantly improved, or even not loose. 4. Periodontitis with alveolar bone atrophy and resorption: with severe periodontitis with alveolar bone atrophy and resorption, the root of the tooth is exposed in the oral cavity, the alveolar bone irreversible loss, the lack of hard tissue support, looseness can be more than 2-3 degrees, it is difficult to restore the need for timely extraction and restoration to avoid affecting the teeth on both sides.
