Cold compress within 1.48 hours can promote local vasoconstriction, reduce bleeding, and achieve the effect of detumescence and pain relief. Wrap the ice cubes with a towel and apply it to the tooth extraction side to prevent the ice cubes from directly contacting the skin and preventing frostbite, or choose an ice pack placed in the cold storage layer of the refrigerator. The cold compress time should not be too long, each time 10- 15 minutes, and then apply after rest; Hot compress: Hot compress after 48 hours can improve the local blood circulation of the wound and promote the swelling to subside. You can apply a hot towel or hot water bottle to your face. Don't put hot water in your mouth to avoid bleeding. Hot compress every time 15-20 minutes, pay attention to the temperature of hot compress to avoid burns. After four days, it has changed from exudation period to repair period. This is why we need to increase the blood supply in this area and help people improve their metabolism. We can use hot towels and hot compresses to strengthen local blood circulation, help people improve their metabolism and promote wound healing.

2. The face is swollen after tooth extraction, considering the serious postoperative reaction. First, it can be treated by infusion. Transfusion is generally antibiotics and hormones, which can reduce swelling and avoid infection. In addition, local gargling can reduce inflammation, and local hot compress can reduce swelling. Usually, the diet should be light, and spicy food and seafood should not be eaten. After eating, you need to rinse your mouth in time to avoid the accumulation of food residues in the tooth extraction socket, thus aggravating the symptoms.

Do not rinse your mouth within 3.24 hours: after tooth extraction, the patient's mouth is in an extremely sensitive state. In order to avoid wound cracking and infection, patients should pay attention to avoid gargling within 24 hours; Don't brush your teeth within 24 hours: On the day of tooth extraction, patients should avoid brushing their teeth, mainly because brushing teeth may cause bleeding and pain. However, oral hygiene should not be neglected. It is suggested that the patient rinse his mouth gently with light salt water after his condition is stable. Postoperative occlusion: In order to promote the coagulation of the wound, patients often need to bite sterile cotton balls after tooth extraction, and pay attention to the occlusion time. If the bite time is not enough, the wound may not be completely solidified, resulting in continuous bleeding. Occlusal time is too long, which will increase the possibility of adhesion between cotton ball and wound. Therefore, it is clinically considered that the occlusal time after tooth extraction is 30 minutes.
