If the tooth is loose after maxillary cyst surgery, if it is only mildly loose, it can be observed temporarily without special treatment; moderate loosening can be fixed; and severe loosening, it is generally recommended to extract the tooth as soon as possible. 1. Mild loosening: no special treatment for the time being, regular observation can be done, but usually pay attention to oral hygiene, and insist on brushing to prevent secondary infection. 2. Moderate loosening: If the loosening is not serious, the tooth can be fixed to prevent the tooth from falling out, for example, fixed with ligature wire, or fixed with fiberglass splint. 3. Severe loosening: If the tooth has no value for retention, the tooth can be extracted directly. For loose teeth caused by surgical trauma, the appropriate treatment should be chosen according to the degree of looseness, and it is recommended to consult a doctor before treatment.
