The post-operative swelling of dental implants is not a cause for concern, but is mainly caused by surgical trauma. The treatment methods are as follows: 1. Take oral anti-inflammatory drugs to prevent infection; 2. Eat liquid food or semi-liquid food within 24 hours after surgery; 3. Pay attention to rest and avoid strenuous exercise, such as swimming and running; 4. Apply ice packs intermittently within 24 hours, and if the face is still slightly swollen after more than 24 hours, change to hot packs; 5. Avoid rinsing and sucking hard after surgery to avoid dislodging of sutures and affecting wound healing; 6, Do not brush your teeth to the surgical area and do not use toothpaste in the first few days after surgery to avoid stimulating the wound and affecting the healing; 7. Pay attention to cleaning the mouth with dental floss to maintain oral hygiene.
