The face may not necessarily be swollen after tooth extraction, depending on the difficulty of extraction, intraoperative operation, postoperative care, personal constitution and other decisions. 1. Swelling of the face after tooth extraction usually occurs when the difficulty of tooth extraction is great, such as the removal of mandibular wisdom teeth. Swelling of the face may also occur if the operation during tooth extraction is more traumatic, such as wide range of flap turning, too low incision of the flap or too tight suture. 2. Generally, on the day of tooth extraction, cold compresses and cold food should be applied as much as possible. If the postoperative care is not proper, face swelling may also occur. 3. The swelling of the face after tooth extraction is also related to the individual’s physical condition, some people have loose tissues, and the tissue exudate is easy to ooze outward, which is also easy to have swelling of the face. There is no need to worry about the swelling of the face after tooth extraction, as it will gradually subside.
