It is normal to feel swollen and numb after operation. Generally, symptoms will gradually improve after 3-4 days. It is suggested that you should not do high-intensity work for one week after operation and have a good rest, which is good for wound healing. You can't brush your teeth in the maxillary area after operation. It is recommended to buy compound chlorhexidine mouthwash in a pharmacy, but you should brush your teeth normally, otherwise the uncleanness in your mouth will also affect wound healing. You can start work one week after operation, but you can't be too tired. It's best to go back to the hospital for stitches one week after operation, and then go back one month or three months.
